INFORMATION SECURITY IN CLOUD COMPUTING TECHNOLOGY
Introduction
Along with the times, computing technology can provide convenience and comfort in
doing daily work that is considered impossible to do in a short time, this happens because of
advances in technology, especially the internet (Suryati et al., 2019) (Mutia, 2016) (Aziz et
al., 2018) [1].
Cloud computing technology or cloud computing which is currently developing
rapidly is a computing processing process that can be accessed via the internet network, with
this the computer will be connected to the cloud server so that it can run a program. The
cloud provides various services such as servers, data storage (databases), software and others
[2].
Cloud computing is a concept of understanding for the creation of local (LAN) and
global (internet) online computing frameworks so that storage media can be accessed
anywhere and used simultaneously (simultaneous access). This cloud is a metaphor of the
internet, as is often the case in computer network diagram images, where the cloud is an
abstraction of a complex infrastructure that is hidden [3].
Cloud computing relies on various resources to achieve economies of scale. Cloud
providers usually use a "pay as you go" model, which causes unexpected operating costs.
This cloud technology has been widely utilized in the business world or in the business world
general public. The cloud was created to make it easier for humans to access programs or
data by various means and anywhere [4].
Storing data in the cloud does not need to be in the form of hard files or hard disks,
because by having an internet network, data can be stored and accessed anywhere. How cloud
computing works by dividing the two parts of the frontend and backend which are connected
to the internet network and work together. Frontend for the display of cloud systems that can
be accessed by users, while the backend is the server and data storage that makes up the cloud
[5].
In the business world, one of the concerns in using this cloud is the security of
confidential data. The risk of data theft and other cybercrime can be very detrimental to a
company or user using this cloud system. So that currently information security with the use
of cloud computing continues to be developed to minimize the risk of data theft [6].
Cloud Computing Discussion
There are many opinions about cloud computing. Many opinions think of the cloud as
a collection of technologies. It is true that there is a set of technologies that usually make up a
cloud environment, but these technologies are not the core of the cloud (Rountree, Derrick;
Castrillo, 2014). Cloud computing is a model for delivering information technology services
provided to users in a flexible manner, virtual servers, large scalability, and service
management. These information technology services can be used by organizations to operate
their business which can facilitate their users (Sullivan, 2009).
Cloud computing means storing and accessing data and programs over the internet
from a remote location using a computer. In order to be considered cloud computing, it is
necessary to access data or programs via the internet. The end result is the same however,
with an internet connection cloud computing can be done anywhere, anytime, and by any
device (K. Chandrasekaran, 2018. Chandrasekaran, 2018. Cloud computing is a new trend in
the field of distributed computing where various parties can develop SOA (Service Oriented
Architecture) based applications and services on the internet network (Herwin, 2011) [7].
Buyya et al. (2009) described cloud computing as the fifth utility along with water,
gas, electricity and telephone. Cloud computing includes on-demand available access to other
utility computing services [8].
According to Laudon and Loudon (2015), cloud computing is a computing mode
where processing activities, storage, software and other services are provided like an
integrated virtual source on a network which is generally the internet. The computing
resources of cloud computing are dispersed and can be accessed based on needs [9].
Cloud Computing Services
The type of user cloud computing service refers to the requirements and objectives of
the cloud computing used. Three types of cloud service models are commonly provided,
namely Infrastructure as a Service (IaaS) which is commonly used by system admins or
network architects, Platform as a Service (PaaS) which is commonly used by developers, and
Software as a Service (SaaS) which is commonly used by users.
Software as a Service (SaaS) provides software resource services that are hosted on
cloud servers. Platform as a Service (PaaS) provides platform access infrastructure, which
allows its own software to be deployed with other applications in the cloud. Infrastructure as
a Service (IaaS) provides services for customers to rent servers for computing, storage, and
network connectivity [10].
Cloud Computing Characteristics
Cloud computing has several characteristics, including (Marks, 2010):
Scalable (Aggregate)
Cloud computing has the ability to provide needs according to user demand.
Elastic
Cloud computing has the ability to increase or lower the operational power of the
application being used.
Self-service on demand
Application requirements are tailored to user requests.
Ubiquitous access
Capabilities that can be accessed from anywhere and using any device or application.
Complete virtualization
The ability to work across multiple infrastructures is known as virtualization to support
ubiquitous capabilities.
Relative consistency
Supports virtualization technology so that it can save costs in the use of information
technology.
Commodity
Being a major requirement in the provision of information technology devices or
allowing more tenants for an application [11].
Cloud Computing Deployment Model
The cloud computing deployment model is divided into four by NIST (2011), namely:
Hybrid Cloud
A composition of two or more clouds (private, community or public) whose entities are
unique but bound together by standards or technology ownership that use data and
application portability.
Public Cloud
Cloud infrastructure is available to the public or a large group that belongs to an
organization.
Community Cloud
Cloud infrastructure is shared by multiple organizations and supports communities that
have shared concerns.
Private Cloud
Cloud infrastructure that is operated only for an enterprise [12].
Cloud Computing Security Threats
According to the Cloud Security Alliance journal, there are 9 top threats that can occur in
cloud computing, including:
Data Breaches
Unauthorized viewing, accessing or retrieving of data by individuals, apps or services.
Configuration Error
Increased vulnerability to data breaches, caused by complex environments.
Insecure Interfaces and Application Programming Interfaces (APIs)
Cloud services depend on these APIs, so they must have secure certification standards,
and controls to avoid threats.
DDOS (Distributed Denial Of Services)
DDoS attacks are called bots or zombies that can be controlled remotely. The
controlled bots are called botnets, which send large requests to the server. As a result,
the server is flooded with requests and unprepared.
Account Hijacking
Attackers can access the system so that they can steal data or manipulate data that can
harm the company.
Malicious Insider
Employees who work inside and commit several crimes such as misuse of user
information.
Insufficient Due Diligence
Organizations that directly accept service offerings from service providers, without
sufficient knowledge.
Abusive Use of Cloud Services
Unethical and illegal actions from consumers by misusing services.
Shared Technology Issues
Occurs in multi-tenant, where services are provided using shared infrastructure so that
different users have access to the same VM (virtual machine) [13].
Pros of Cloud Computing in Business
Some of the advantages of Cloud Computing (Ashari, & Setiawan, 2011) (Fardani, &
Surendro, 2011) (Anik, 2013) (Singh, & Hemalatha, 2012) (Achmad, & Paulus, 2015)
(Warjiyono, 2014), including:
Save on investment costs
Save time
Easier operations and management
Improve data availability and availability
Save operational costs [14].
Disadvantages of Cloud Computing
Internet connection, if the internet has problems, the computer will not be able to be
used to access the cloud so adequate and stable bandwidth is needed,
Companies that rent cloud computing services do not have direct access to resources.
If the service provider's server is damaged or the backup is poor, the company will
suffer losses [15].
Conclusion
Cloud computing is a combination of utilizing computing technology with flexible
internet-based development that can be used anytime, anywhere and on any device.
The development of cloud computing today really needs to be guided by an increase
in its security system, to control and minimize data theft or other cybercrime which is
currently still rampant.
Therefore, research on information security in cloud computing must certainly
continue to be developed, because cloud computing will be very useful and facilitate work for
general users and large companies.

Cloud Computing Discussion
There are many opinions about cloud computing. Many opinions think of the cloud as
a collection of technologies. It is true that there is a set of technologies that usually make up a
cloud environment, but these technologies are not the core of the cloud (Rountree, Derrick;
Castrillo, 2014). Cloud computing is a model for delivering information technology services
provided to users in a flexible manner, virtual servers, large scalability, and service
management. These information technology services can be used by organizations to operate
their business which can facilitate their users (Sullivan, 2009).
Cloud computing means storing and accessing data and programs over the internet
from a remote location using a computer. In order to be considered cloud computing, it is
necessary to access data or programs via the internet. The end result is the same however,
with an internet connection cloud computing can be done anywhere, anytime, and by any
device (K. Chandrasekaran, 2018. Chandrasekaran, 2018. Cloud computing is a new trend in
the field of distributed computing where various parties can develop SOA (Service Oriented
Architecture) based applications and services on the internet network (Herwin, 2011) [7].
Buyya et al. (2009) described cloud computing as the fifth utility along with water,
gas, electricity and telephone. Cloud computing includes on-demand available access to other
utility computing services [8].
According to Laudon and Loudon (2015), cloud computing is a computing mode
where processing activities, storage, software and other services are provided like an
integrated virtual source on a network which is generally the internet. The computing
resources of cloud computing are dispersed and can be accessed based on needs [9].
Cloud Computing Services
The type of user cloud computing service refers to the requirements and objectives of
the cloud computing used. Three types of cloud service models are commonly provided,
namely Infrastructure as a Service (IaaS) which is commonly used by system admins or
network architects, Platform as a Service (PaaS) which is commonly used by developers, and
Software as a Service (SaaS) which is commonly used by users.
Software as a Service (SaaS) provides software resource services that are hosted on
cloud servers. Platform as a Service (PaaS) provides platform access infrastructure, which
allows its own software to be deployed with other applications in the cloud. Infrastructure as
a Service (IaaS) provides services for customers to rent servers for computing, storage, and
network connectivity [10].
Cloud Computing Characteristics
Cloud computing has several characteristics, including (Marks, 2010):
Scalable (Aggregate)
Cloud computing has the ability to provide needs according to user demand.
Elastic
Cloud computing has the ability to increase or lower the operational power of the
application being used.
Self-service on demand
Application requirements are tailored to user requests.
Ubiquitous access
Capabilities that can be accessed from anywhere and using any device or application.
Complete virtualization
The ability to work across multiple infrastructures is known as virtualization to support
ubiquitous capabilities.
Relative consistency
Supports virtualization technology so that it can save costs in the use of information
technology.
Commodity
Being a major requirement in the provision of information technology devices or
allowing more tenants for an application [11].
Cloud Computing Deployment Model
The cloud computing deployment model is divided into four by NIST (2011), namely:
Hybrid Cloud
A composition of two or more clouds (private, community or public) whose entities are
unique but bound together by standards or technology ownership that use data and
application portability.
Public Cloud
Cloud infrastructure is available to the public or a large group that belongs to an
organization.
Community Cloud
Cloud infrastructure is shared by multiple organizations and supports communities that
have shared concerns.
Private Cloud
Cloud infrastructure that is operated only for an enterprise [12].
Cloud Computing Security Threats
According to the Cloud Security Alliance journal, there are 9 top threats that can occur in
cloud computing, including:
Data Breaches
Unauthorized viewing, accessing or retrieving of data by individuals, apps or services.
Configuration Error
Increased vulnerability to data breaches, caused by complex environments.
Insecure Interfaces and Application Programming Interfaces (APIs)
Cloud services depend on these APIs, so they must have secure certification standards,
and controls to avoid threats.
DDOS (Distributed Denial Of Services)
DDoS attacks are called bots or zombies that can be controlled remotely. The
controlled bots are called botnets, which send large requests to the server. As a result,
the server is flooded with requests and unprepared.
Account Hijacking
Attackers can access the system so that they can steal data or manipulate data that can
harm the company.
Malicious Insider
Employees who work inside and commit several crimes such as misuse of user
information.
Insufficient Due Diligence
Organizations that directly accept service offerings from service providers, without
sufficient knowledge.
Abusive Use of Cloud Services
Unethical and illegal actions from consumers by misusing services.
Shared Technology Issues
Occurs in multi-tenant, where services are provided using shared infrastructure so that
different users have access to the same VM (virtual machine) [13].
Pros of Cloud Computing in Business
Some of the advantages of Cloud Computing (Ashari, & Setiawan, 2011) (Fardani, &
Surendro, 2011) (Anik, 2013) (Singh, & Hemalatha, 2012) (Achmad, & Paulus, 2015)
(Warjiyono, 2014), including:
Save on investment costs
Save time
Easier operations and management
Improve data availability and availability
Save operational costs [14].
Disadvantages of Cloud Computing
Internet connection, if the internet has problems, the computer will not be able to be
used to access the cloud so adequate and stable bandwidth is needed,
Companies that rent cloud computing services do not have direct access to resources.
If the service provider's server is damaged or the backup is poor, the company will
suffer losses [15].
Conclusion
Cloud computing is a combination of utilizing computing technology with flexible
internet-based development that can be used anytime, anywhere and on any device.
The development of cloud computing today really needs to be guided by an increase
in its security system, to control and minimize data theft or other cybercrime which is

where processing activities, storage, software and other services are provided like an
integrated virtual source on a network which is generally the internet. The computing
resources of cloud computing are dispersed and can be accessed based on needs [9].
Cloud Computing Services
The type of user cloud computing service refers to the requirements and objectives of
the cloud computing used. Three types of cloud service models are commonly provided,
namely Infrastructure as a Service (IaaS) which is commonly used by system admins or
network architects, Platform as a Service (PaaS) which is commonly used by developers, and
Software as a Service (SaaS) which is commonly used by users.
Software as a Service (SaaS) provides software resource services that are hosted on
cloud servers. Platform as a Service (PaaS) provides platform access infrastructure, which
allows its own software to be deployed with other applications in the cloud. Infrastructure as
a Service (IaaS) provides services for customers to rent servers for computing, storage, and
network connectivity [10].
Cloud Computing Characteristics
Cloud computing has several characteristics, including (Marks, 2010):
Scalable (Aggregate)
Cloud computing has the ability to provide needs according to user demand.
Elastic
Cloud computing has the ability to increase or lower the operational power of the
application being used.
Self-service on demand
Application requirements are tailored to user requests.
Ubiquitous access
Capabilities that can be accessed from anywhere and using any device or application.
Complete virtualization
The ability to work across multiple infrastructures is known as virtualization to support
ubiquitous capabilities.
Relative consistency
Supports virtualization technology so that it can save costs in the use of information
technology.
Commodity
Being a major requirement in the provision of information technology devices or
allowing more tenants for an application [11].
Cloud Computing Deployment Model
The cloud computing deployment model is divided into four by NIST (2011), namely:
Hybrid Cloud
A composition of two or more clouds (private, community or public) whose entities are
unique but bound together by standards or technology ownership that use data and
application portability.
Public Cloud
Cloud infrastructure is available to the public or a large group that belongs to an
organization.
Community Cloud
Cloud infrastructure is shared by multiple organizations and supports communities that
have shared concerns.
Private Cloud
Cloud infrastructure that is operated only for an enterprise [12].
Cloud Computing Security Threats
According to the Cloud Security Alliance journal, there are 9 top threats that can occur in
cloud computing, including:
Data Breaches
Unauthorized viewing, accessing or retrieving of data by individuals, apps or services.
Configuration Error
Increased vulnerability to data breaches, caused by complex environments.
Insecure Interfaces and Application Programming Interfaces (APIs)
Cloud services depend on these APIs, so they must have secure certification standards,
and controls to avoid threats.
DDOS (Distributed Denial Of Services)
DDoS attacks are called bots or zombies that can be controlled remotely. The
controlled bots are called botnets, which send large requests to the server. As a result,
the server is flooded with requests and unprepared.
Account Hijacking
Attackers can access the system so that they can steal data or manipulate data that can
harm the company.
Malicious Insider
Employees who work inside and commit several crimes such as misuse of user
information.
Insufficient Due Diligence
Organizations that directly accept service offerings from service providers, without
sufficient knowledge.
Abusive Use of Cloud Services
Unethical and illegal actions from consumers by misusing services.
Shared Technology Issues
Occurs in multi-tenant, where services are provided using shared infrastructure so that
different users have access to the same VM (virtual machine) [13].
Pros of Cloud Computing in Business
Some of the advantages of Cloud Computing (Ashari, & Setiawan, 2011) (Fardani, &
Surendro, 2011) (Anik, 2013) (Singh, & Hemalatha, 2012) (Achmad, & Paulus, 2015)
(Warjiyono, 2014), including:
Save on investment costs
Save time
Easier operations and management
Improve data availability and availability
Save operational costs [14].
Disadvantages of Cloud Computing
Internet connection, if the internet has problems, the computer will not be able to be
used to access the cloud so adequate and stable bandwidth is needed,
Companies that rent cloud computing services do not have direct access to resources.
If the service provider's server is damaged or the backup is poor, the company will
suffer losses [15].
Conclusion
Cloud computing is a combination of utilizing computing technology with flexible
internet-based development that can be used anytime, anywhere and on any device.
The development of cloud computing today really needs to be guided by an increase
in its security system, to control and minimize data theft or other cybercrime which is
currently still rampant.
Therefore, research on information security in cloud computing must certainly
continue to be developed, because cloud computing will be very useful and facilitate work for
general users and large companies.
Cloud Computing Discussion
There are many opinions about cloud computing. Many opinions think of the cloud as
a collection of technologies. It is true that there is a set of technologies that usually make up a
cloud environment, but these technologies are not the core of the cloud (Rountree, Derrick;
Castrillo, 2014). Cloud computing is a model for delivering information technology services
provided to users in a flexible manner, virtual servers, large scalability, and service
management. These information technology services can be used by organizations to operate
their business which can facilitate their users (Sullivan, 2009).
Cloud computing means storing and accessing data and programs over the internet
from a remote location using a computer. In order to be considered cloud computing, it is
necessary to access data or programs via the internet. The end result is the same however,
with an internet connection cloud computing can be done anywhere, anytime, and by any
device (K. Chandrasekaran, 2018. Chandrasekaran, 2018. Cloud computing is a new trend in
the field of distributed computing where various parties can develop SOA (Service Oriented
Architecture) based applications and services on the internet network (Herwin, 2011) [7].
Buyya et al. (2009) described cloud computing as the fifth utility along with water,
gas, electricity and telephone. Cloud computing includes on-demand available access to other
utility computing services [8].
According to Laudon and Loudon (2015), cloud computing is a computing mode

The cloud computing deployment model is divided into four by NIST (2011), namely:
Hybrid Cloud
A composition of two or more clouds (private, community or public) whose entities are
unique but bound together by standards or technology ownership that use data and
application portability.
Public Cloud
Cloud infrastructure is available to the public or a large group that belongs to an
organization.
Community Cloud
Cloud infrastructure is shared by multiple organizations and supports communities that
have shared concerns.
Private Cloud
Cloud infrastructure that is operated only for an enterprise [12].
Cloud Computing Security Threats
According to the Cloud Security Alliance journal, there are 9 top threats that can occur in
cloud computing, including:
Data Breaches
Unauthorized viewing, accessing or retrieving of data by individuals, apps or services.
Configuration Error
Increased vulnerability to data breaches, caused by complex environments.
Insecure Interfaces and Application Programming Interfaces (APIs)
Cloud services depend on these APIs, so they must have secure certification standards,
and controls to avoid threats.
DDOS (Distributed Denial Of Services)
DDoS attacks are called bots or zombies that can be controlled remotely. The
controlled bots are called botnets, which send large requests to the server. As a result,
the server is flooded with requests and unprepared.
Account Hijacking
Attackers can access the system so that they can steal data or manipulate data that can
harm the company.
Malicious Insider
Employees who work inside and commit several crimes such as misuse of user
information.
Insufficient Due Diligence
Organizations that directly accept service offerings from service providers, without
sufficient knowledge.
Abusive Use of Cloud Services
Unethical and illegal actions from consumers by misusing services.
Shared Technology Issues
Occurs in multi-tenant, where services are provided using shared infrastructure so that
different users have access to the same VM (virtual machine) [13].
Pros of Cloud Computing in Business
Some of the advantages of Cloud Computing (Ashari, & Setiawan, 2011) (Fardani, &
Surendro, 2011) (Anik, 2013) (Singh, & Hemalatha, 2012) (Achmad, & Paulus, 2015)
(Warjiyono, 2014), including:
Save on investment costs
Save time
Easier operations and management
Improve data availability and availability
Save operational costs [14].
Disadvantages of Cloud Computing
Internet connection, if the internet has problems, the computer will not be able to be
used to access the cloud so adequate and stable bandwidth is needed,
Companies that rent cloud computing services do not have direct access to resources.
If the service provider's server is damaged or the backup is poor, the company will
suffer losses [15].
Conclusion
Cloud computing is a combination of utilizing computing technology with flexible
internet-based development that can be used anytime, anywhere and on any device.
The development of cloud computing today really needs to be guided by an increase
in its security system, to control and minimize data theft or other cybercrime which is
currently still rampant.
Therefore, research on information security in cloud computing must certainly
continue to be developed, because cloud computing will be very useful and facilitate work for
general users and large companies.
Cloud Computing Discussion
There are many opinions about cloud computing. Many opinions think of the cloud as
a collection of technologies. It is true that there is a set of technologies that usually make up a
cloud environment, but these technologies are not the core of the cloud (Rountree, Derrick;
Castrillo, 2014). Cloud computing is a model for delivering information technology services
provided to users in a flexible manner, virtual servers, large scalability, and service
management. These information technology services can be used by organizations to operate
their business which can facilitate their users (Sullivan, 2009).
Cloud computing means storing and accessing data and programs over the internet
from a remote location using a computer. In order to be considered cloud computing, it is
necessary to access data or programs via the internet. The end result is the same however,
with an internet connection cloud computing can be done anywhere, anytime, and by any
device (K. Chandrasekaran, 2018. Chandrasekaran, 2018. Cloud computing is a new trend in
the field of distributed computing where various parties can develop SOA (Service Oriented
Architecture) based applications and services on the internet network (Herwin, 2011) [7].
Buyya et al. (2009) described cloud computing as the fifth utility along with water,
gas, electricity and telephone. Cloud computing includes on-demand available access to other
utility computing services [8].
According to Laudon and Loudon (2015), cloud computing is a computing mode
where processing activities, storage, software and other services are provided like an
integrated virtual source on a network which is generally the internet. The computing
resources of cloud computing are dispersed and can be accessed based on needs [9].
Cloud Computing Services
The type of user cloud computing service refers to the requirements and objectives of
the cloud computing used. Three types of cloud service models are commonly provided,
namely Infrastructure as a Service (IaaS) which is commonly used by system admins or
network architects, Platform as a Service (PaaS) which is commonly used by developers, and
Software as a Service (SaaS) which is commonly used by users.
Software as a Service (SaaS) provides software resource services that are hosted on
cloud servers. Platform as a Service (PaaS) provides platform access infrastructure, which
allows its own software to be deployed with other applications in the cloud. Infrastructure as
a Service (IaaS) provides services for customers to rent servers for computing, storage, and
network connectivity [10].
Cloud Computing Characteristics
Cloud computing has several characteristics, including (Marks, 2010):
Scalable (Aggregate)
Cloud computing has the ability to provide needs according to user demand.
Elastic
Cloud computing has the ability to increase or lower the operational power of the
application being used.
Self-service on demand
Application requirements are tailored to user requests.
Ubiquitous access
Capabilities that can be accessed from anywhere and using any device or application.
Complete virtualization
The ability to work across multiple infrastructures is known as virtualization to support
ubiquitous capabilities.
Relative consistency
Supports virtualization technology so that it can save costs in the use of information
technology.
Commodity
Being a major requirement in the provision of information technology devices or
allowing more tenants for an application [11].

different users have access to the same VM (virtual machine) [13].
Pros of Cloud Computing in Business
Some of the advantages of Cloud Computing (Ashari, & Setiawan, 2011) (Fardani, &
Surendro, 2011) (Anik, 2013) (Singh, & Hemalatha, 2012) (Achmad, & Paulus, 2015)
(Warjiyono, 2014), including:
Save on investment costs
Save time
Easier operations and management
Improve data availability and availability
Save operational costs [14].
Disadvantages of Cloud Computing
Internet connection, if the internet has problems, the computer will not be able to be
used to access the cloud so adequate and stable bandwidth is needed,
Companies that rent cloud computing services do not have direct access to resources.
If the service provider's server is damaged or the backup is poor, the company will
suffer losses [15].
Conclusion
Cloud computing is a combination of utilizing computing technology with flexible
internet-based development that can be used anytime, anywhere and on any device.
The development of cloud computing today really needs to be guided by an increase
in its security system, to control and minimize data theft or other cybercrime which is
currently still rampant.
Therefore, research on information security in cloud computing must certainly
continue to be developed, because cloud computing will be very useful and facilitate work for
general users and large companies.
Cloud Computing Discussion
There are many opinions about cloud computing. Many opinions think of the cloud as
a collection of technologies. It is true that there is a set of technologies that usually make up a
cloud environment, but these technologies are not the core of the cloud (Rountree, Derrick;
Castrillo, 2014). Cloud computing is a model for delivering information technology services
provided to users in a flexible manner, virtual servers, large scalability, and service
management. These information technology services can be used by organizations to operate
their business which can facilitate their users (Sullivan, 2009).
Cloud computing means storing and accessing data and programs over the internet
from a remote location using a computer. In order to be considered cloud computing, it is
necessary to access data or programs via the internet. The end result is the same however,
with an internet connection cloud computing can be done anywhere, anytime, and by any
device (K. Chandrasekaran, 2018. Chandrasekaran, 2018. Cloud computing is a new trend in
the field of distributed computing where various parties can develop SOA (Service Oriented
Architecture) based applications and services on the internet network (Herwin, 2011) [7].
Buyya et al. (2009) described cloud computing as the fifth utility along with water,
gas, electricity and telephone. Cloud computing includes on-demand available access to other
utility computing services [8].
According to Laudon and Loudon (2015), cloud computing is a computing mode
where processing activities, storage, software and other services are provided like an
integrated virtual source on a network which is generally the internet. The computing
resources of cloud computing are dispersed and can be accessed based on needs [9].
Cloud Computing Services
The type of user cloud computing service refers to the requirements and objectives of
the cloud computing used. Three types of cloud service models are commonly provided,
namely Infrastructure as a Service (IaaS) which is commonly used by system admins or
network architects, Platform as a Service (PaaS) which is commonly used by developers, and
Software as a Service (SaaS) which is commonly used by users.
Software as a Service (SaaS) provides software resource services that are hosted on
cloud servers. Platform as a Service (PaaS) provides platform access infrastructure, which
allows its own software to be deployed with other applications in the cloud. Infrastructure as
a Service (IaaS) provides services for customers to rent servers for computing, storage, and
network connectivity [10].
Cloud Computing Characteristics
Cloud computing has several characteristics, including (Marks, 2010):
Scalable (Aggregate)
Cloud computing has the ability to provide needs according to user demand.
Elastic
Cloud computing has the ability to increase or lower the operational power of the
application being used.
Self-service on demand
Application requirements are tailored to user requests.
Ubiquitous access
Capabilities that can be accessed from anywhere and using any device or application.
Complete virtualization
The ability to work across multiple infrastructures is known as virtualization to support
ubiquitous capabilities.
Relative consistency
Supports virtualization technology so that it can save costs in the use of information
technology.
Commodity
Being a major requirement in the provision of information technology devices or
allowing more tenants for an application [11].
Cloud Computing Deployment Model
The cloud computing deployment model is divided into four by NIST (2011), namely:
Hybrid Cloud
A composition of two or more clouds (private, community or public) whose entities are
unique but bound together by standards or technology ownership that use data and
application portability.
Public Cloud
Cloud infrastructure is available to the public or a large group that belongs to an
organization.
Community Cloud
Cloud infrastructure is shared by multiple organizations and supports communities that
have shared concerns.
Private Cloud
Cloud infrastructure that is operated only for an enterprise [12].
Cloud Computing Security Threats
According to the Cloud Security Alliance journal, there are 9 top threats that can occur in
cloud computing, including:
Data Breaches
Unauthorized viewing, accessing or retrieving of data by individuals, apps or services.
Configuration Error
Increased vulnerability to data breaches, caused by complex environments.
Insecure Interfaces and Application Programming Interfaces (APIs)
Cloud services depend on these APIs, so they must have secure certification standards,
and controls to avoid threats.
DDOS (Distributed Denial Of Services)
DDoS attacks are called bots or zombies that can be controlled remotely. The
controlled bots are called botnets, which send large requests to the server. As a result,
the server is flooded with requests and unprepared.
Account Hijacking
Attackers can access the system so that they can steal data or manipulate data that can
harm the company.
Malicious Insider
Employees who work inside and commit several crimes such as misuse of user
information.
Insufficient Due Diligence
Organizations that directly accept service offerings from service providers, without
sufficient knowledge.
Abusive Use of Cloud Services
Unethical and illegal actions from consumers by misusing services.
Shared Technology Issues
Occurs in multi-tenant, where services are provided using shared infrastructure so that
different users have access to the same VM (virtual machine) [13].

Castrillo, 2014). Cloud computing is a model for delivering information technology services
provided to users in a flexible manner, virtual servers, large scalability, and service
management. These information technology services can be used by organizations to operate
their business which can facilitate their users (Sullivan, 2009).
Cloud computing means storing and accessing data and programs over the internet
from a remote location using a computer. In order to be considered cloud computing, it is
necessary to access data or programs via the internet. The end result is the same however,
with an internet connection cloud computing can be done anywhere, anytime, and by any
device (K. Chandrasekaran, 2018. Chandrasekaran, 2018. Cloud computing is a new trend in
the field of distributed computing where various parties can develop SOA (Service Oriented
Architecture) based applications and services on the internet network (Herwin, 2011) [7].
Buyya et al. (2009) described cloud computing as the fifth utility along with water,
gas, electricity and telephone. Cloud computing includes on-demand available access to other
utility computing services [8].
According to Laudon and Loudon (2015), cloud computing is a computing mode
where processing activities, storage, software and other services are provided like an
integrated virtual source on a network which is generally the internet. The computing
resources of cloud computing are dispersed and can be accessed based on needs [9].
Cloud Computing Services
The type of user cloud computing service refers to the requirements and objectives of
the cloud computing used. Three types of cloud service models are commonly provided,
namely Infrastructure as a Service (IaaS) which is commonly used by system admins or
network architects, Platform as a Service (PaaS) which is commonly used by developers, and
Software as a Service (SaaS) which is commonly used by users.
Software as a Service (SaaS) provides software resource services that are hosted on
cloud servers. Platform as a Service (PaaS) provides platform access infrastructure, which
allows its own software to be deployed with other applications in the cloud. Infrastructure as
a Service (IaaS) provides services for customers to rent servers for computing, storage, and
network connectivity [10].
Cloud Computing Characteristics
Cloud computing has several characteristics, including (Marks, 2010):
Scalable (Aggregate)
Cloud computing has the ability to provide needs according to user demand.
Elastic
Cloud computing has the ability to increase or lower the operational power of the
application being used.
Self-service on demand
Application requirements are tailored to user requests.
Ubiquitous access
Capabilities that can be accessed from anywhere and using any device or application.
Complete virtualization
The ability to work across multiple infrastructures is known as virtualization to support
ubiquitous capabilities.
Relative consistency
Supports virtualization technology so that it can save costs in the use of information
technology.
Commodity
Being a major requirement in the provision of information technology devices or
allowing more tenants for an application [11].
Cloud Computing Deployment Model
The cloud computing deployment model is divided into four by NIST (2011), namely:
Hybrid Cloud
A composition of two or more clouds (private, community or public) whose entities are
unique but bound together by standards or technology ownership that use data and
application portability.
Public Cloud
Cloud infrastructure is available to the public or a large group that belongs to an
organization.
Community Cloud
Cloud infrastructure is shared by multiple organizations and supports communities that
have shared concerns.
Private Cloud
Cloud infrastructure that is operated only for an enterprise [12].
Cloud Computing Security Threats
According to the Cloud Security Alliance journal, there are 9 top threats that can occur in
cloud computing, including:
Data Breaches
Unauthorized viewing, accessing or retrieving of data by individuals, apps or services.
Configuration Error
Increased vulnerability to data breaches, caused by complex environments.
Insecure Interfaces and Application Programming Interfaces (APIs)
Cloud services depend on these APIs, so they must have secure certification standards,
and controls to avoid threats.
DDOS (Distributed Denial Of Services)
DDoS attacks are called bots or zombies that can be controlled remotely. The
controlled bots are called botnets, which send large requests to the server. As a result,
the server is flooded with requests and unprepared.
Account Hijacking
Attackers can access the system so that they can steal data or manipulate data that can
harm the company.
Malicious Insider
Employees who work inside and commit several crimes such as misuse of user
information.
Insufficient Due Diligence
Organizations that directly accept service offerings from service providers, without
sufficient knowledge.
Abusive Use of Cloud Services
Unethical and illegal actions from consumers by misusing services.
Shared Technology Issues
Occurs in multi-tenant, where services are provided using shared infrastructure so that
different users have access to the same VM (virtual machine) [13].
Pros of Cloud Computing in Business
Some of the advantages of Cloud Computing (Ashari, & Setiawan, 2011) (Fardani, &
Surendro, 2011) (Anik, 2013) (Singh, & Hemalatha, 2012) (Achmad, & Paulus, 2015)
(Warjiyono, 2014), including:
Save on investment costs
Save time
Easier operations and management
Improve data availability and availability
Save operational costs [14].
Disadvantages of Cloud Computing
Internet connection, if the internet has problems, the computer will not be able to be
used to access the cloud so adequate and stable bandwidth is needed,
Companies that rent cloud computing services do not have direct access to resources.
If the service provider's server is damaged or the backup is poor, the company will
suffer losses [15].
Conclusion
Cloud computing is a combination of utilizing computing technology with flexible
internet-based development that can be used anytime, anywhere and on any device.
The development of cloud computing today really needs to be guided by an increase
in its security system, to control and minimize data theft or other cybercrime which is
currently still rampant.
Therefore, research on information security in cloud computing must certainly
continue to be developed, because cloud computing will be very useful and facilitate work for
general users and large companies.

network architects, Platform as a Service (PaaS) which is commonly used by developers, and
Software as a Service (SaaS) which is commonly used by users.
Software as a Service (SaaS) provides software resource services that are hosted on
cloud servers. Platform as a Service (PaaS) provides platform access infrastructure, which
allows its own software to be deployed with other applications in the cloud. Infrastructure as
a Service (IaaS) provides services for customers to rent servers for computing, storage, and
network connectivity [10].
Cloud Computing Characteristics
Cloud computing has several characteristics, including (Marks, 2010):
Scalable (Aggregate)
Cloud computing has the ability to provide needs according to user demand.
Elastic
Cloud computing has the ability to increase or lower the operational power of the
application being used.
Self-service on demand
Application requirements are tailored to user requests.
Ubiquitous access
Capabilities that can be accessed from anywhere and using any device or application.
Complete virtualization
The ability to work across multiple infrastructures is known as virtualization to support
ubiquitous capabilities.
Relative consistency
Supports virtualization technology so that it can save costs in the use of information
technology.
Commodity
Being a major requirement in the provision of information technology devices or
allowing more tenants for an application [11].
Cloud Computing Deployment Model
The cloud computing deployment model is divided into four by NIST (2011), namely:
Hybrid Cloud
A composition of two or more clouds (private, community or public) whose entities are
unique but bound together by standards or technology ownership that use data and
application portability.
Public Cloud
Cloud infrastructure is available to the public or a large group that belongs to an
organization.
Community Cloud
Cloud infrastructure is shared by multiple organizations and supports communities that
have shared concerns.
Private Cloud
Cloud infrastructure that is operated only for an enterprise [12].
Cloud Computing Security Threats
According to the Cloud Security Alliance journal, there are 9 top threats that can occur in
cloud computing, including:
Data Breaches
Unauthorized viewing, accessing or retrieving of data by individuals, apps or services.
Configuration Error
Increased vulnerability to data breaches, caused by complex environments.
Insecure Interfaces and Application Programming Interfaces (APIs)
Cloud services depend on these APIs, so they must have secure certification standards,
and controls to avoid threats.
DDOS (Distributed Denial Of Services)
DDoS attacks are called bots or zombies that can be controlled remotely. The
controlled bots are called botnets, which send large requests to the server. As a result,
the server is flooded with requests and unprepared.
Account Hijacking
Attackers can access the system so that they can steal data or manipulate data that can
harm the company.
Malicious Insider
Employees who work inside and commit several crimes such as misuse of user
information.
Insufficient Due Diligence
Organizations that directly accept service offerings from service providers, without
sufficient knowledge.
Abusive Use of Cloud Services
Unethical and illegal actions from consumers by misusing services.
Shared Technology Issues
Occurs in multi-tenant, where services are provided using shared infrastructure so that
different users have access to the same VM (virtual machine) [13].
Pros of Cloud Computing in Business
Some of the advantages of Cloud Computing (Ashari, & Setiawan, 2011) (Fardani, &
Surendro, 2011) (Anik, 2013) (Singh, & Hemalatha, 2012) (Achmad, & Paulus, 2015)
(Warjiyono, 2014), including:
Save on investment costs
Save time
Easier operations and management
Improve data availability and availability
Save operational costs [14].
Disadvantages of Cloud Computing
Internet connection, if the internet has problems, the computer will not be able to be
used to access the cloud so adequate and stable bandwidth is needed,
Companies that rent cloud computing services do not have direct access to resources.
If the service provider's server is damaged or the backup is poor, the company will
suffer losses [15].
Conclusion
Cloud computing is a combination of utilizing computing technology with flexible
internet-based development that can be used anytime, anywhere and on any device.
The development of cloud computing today really needs to be guided by an increase
in its security system, to control and minimize data theft or other cybercrime which is
currently still rampant.
Therefore, research on information security in cloud computing must certainly
continue to be developed, because cloud computing will be very useful and facilitate work for
general users and large companies.
Cloud Computing Discussion
There are many opinions about cloud computing. Many opinions think of the cloud as
a collection of technologies. It is true that there is a set of technologies that usually make up a
cloud environment, but these technologies are not the core of the cloud (Rountree, Derrick;
Castrillo, 2014). Cloud computing is a model for delivering information technology services
provided to users in a flexible manner, virtual servers, large scalability, and service
management. These information technology services can be used by organizations to operate
their business which can facilitate their users (Sullivan, 2009).
Cloud computing means storing and accessing data and programs over the internet
from a remote location using a computer. In order to be considered cloud computing, it is
necessary to access data or programs via the internet. The end result is the same however,
with an internet connection cloud computing can be done anywhere, anytime, and by any
device (K. Chandrasekaran, 2018. Chandrasekaran, 2018. Cloud computing is a new trend in
the field of distributed computing where various parties can develop SOA (Service Oriented
Architecture) based applications and services on the internet network (Herwin, 2011) [7].
Buyya et al. (2009) described cloud computing as the fifth utility along with water,
gas, electricity and telephone. Cloud computing includes on-demand available access to other
utility computing services [8].
According to Laudon and Loudon (2015), cloud computing is a computing mode
where processing activities, storage, software and other services are provided like an
integrated virtual source on a network which is generally the internet. The computing
resources of cloud computing are dispersed and can be accessed based on needs [9].

have shared concerns.
Private Cloud
Cloud infrastructure that is operated only for an enterprise [12].
Cloud Computing Security Threats
According to the Cloud Security Alliance journal, there are 9 top threats that can occur in
cloud computing, including:
Data Breaches
Unauthorized viewing, accessing or retrieving of data by individuals, apps or services.
Configuration Error
Increased vulnerability to data breaches, caused by complex environments.
Insecure Interfaces and Application Programming Interfaces (APIs)
Cloud services depend on these APIs, so they must have secure certification standards,
and controls to avoid threats.
DDOS (Distributed Denial Of Services)
DDoS attacks are called bots or zombies that can be controlled remotely. The
controlled bots are called botnets, which send large requests to the server. As a result,
the server is flooded with requests and unprepared.
Account Hijacking
Attackers can access the system so that they can steal data or manipulate data that can
harm the company.
Malicious Insider
Employees who work inside and commit several crimes such as misuse of user
information.
Insufficient Due Diligence
Organizations that directly accept service offerings from service providers, without
sufficient knowledge.
Abusive Use of Cloud Services
Unethical and illegal actions from consumers by misusing services.
Shared Technology Issues
Occurs in multi-tenant, where services are provided using shared infrastructure so that
different users have access to the same VM (virtual machine) [13].
Pros of Cloud Computing in Business
Some of the advantages of Cloud Computing (Ashari, & Setiawan, 2011) (Fardani, &
Surendro, 2011) (Anik, 2013) (Singh, & Hemalatha, 2012) (Achmad, & Paulus, 2015)
(Warjiyono, 2014), including:
Save on investment costs
Save time
Easier operations and management
Improve data availability and availability
Save operational costs [14].
Disadvantages of Cloud Computing
Internet connection, if the internet has problems, the computer will not be able to be
used to access the cloud so adequate and stable bandwidth is needed,
Companies that rent cloud computing services do not have direct access to resources.
If the service provider's server is damaged or the backup is poor, the company will
suffer losses [15].
Conclusion
Cloud computing is a combination of utilizing computing technology with flexible
internet-based development that can be used anytime, anywhere and on any device.
The development of cloud computing today really needs to be guided by an increase
in its security system, to control and minimize data theft or other cybercrime which is
currently still rampant.
Therefore, research on information security in cloud computing must certainly
continue to be developed, because cloud computing will be very useful and facilitate work for
general users and large companies.
Cloud Computing Discussion
There are many opinions about cloud computing. Many opinions think of the cloud as
a collection of technologies. It is true that there is a set of technologies that usually make up a
cloud environment, but these technologies are not the core of the cloud (Rountree, Derrick;
Castrillo, 2014). Cloud computing is a model for delivering information technology services
provided to users in a flexible manner, virtual servers, large scalability, and service
management. These information technology services can be used by organizations to operate
their business which can facilitate their users (Sullivan, 2009).
Cloud computing means storing and accessing data and programs over the internet
from a remote location using a computer. In order to be considered cloud computing, it is
necessary to access data or programs via the internet. The end result is the same however,
with an internet connection cloud computing can be done anywhere, anytime, and by any
device (K. Chandrasekaran, 2018. Chandrasekaran, 2018. Cloud computing is a new trend in
the field of distributed computing where various parties can develop SOA (Service Oriented
Architecture) based applications and services on the internet network (Herwin, 2011) [7].
Buyya et al. (2009) described cloud computing as the fifth utility along with water,
gas, electricity and telephone. Cloud computing includes on-demand available access to other
utility computing services [8].
According to Laudon and Loudon (2015), cloud computing is a computing mode
where processing activities, storage, software and other services are provided like an
integrated virtual source on a network which is generally the internet. The computing
resources of cloud computing are dispersed and can be accessed based on needs [9].
Cloud Computing Services
The type of user cloud computing service refers to the requirements and objectives of
the cloud computing used. Three types of cloud service models are commonly provided,
namely Infrastructure as a Service (IaaS) which is commonly used by system admins or
network architects, Platform as a Service (PaaS) which is commonly used by developers, and
Software as a Service (SaaS) which is commonly used by users.
Software as a Service (SaaS) provides software resource services that are hosted on
cloud servers. Platform as a Service (PaaS) provides platform access infrastructure, which
allows its own software to be deployed with other applications in the cloud. Infrastructure as
a Service (IaaS) provides services for customers to rent servers for computing, storage, and
network connectivity [10].
Cloud Computing Characteristics
Cloud computing has several characteristics, including (Marks, 2010):
Scalable (Aggregate)
Cloud computing has the ability to provide needs according to user demand.
Elastic
Cloud computing has the ability to increase or lower the operational power of the
application being used.
Self-service on demand
Application requirements are tailored to user requests.
Ubiquitous access
Capabilities that can be accessed from anywhere and using any device or application.
Complete virtualization
The ability to work across multiple infrastructures is known as virtualization to support
ubiquitous capabilities.
Relative consistency
Supports virtualization technology so that it can save costs in the use of information
technology.
Commodity
Being a major requirement in the provision of information technology devices or
allowing more tenants for an application [11].
Cloud Computing Deployment Model
The cloud computing deployment model is divided into four by NIST (2011), namely:
Hybrid Cloud
A composition of two or more clouds (private, community or public) whose entities are
unique but bound together by standards or technology ownership that use data and
application portability.
Public Cloud
Cloud infrastructure is available to the public or a large group that belongs to an
organization.
Community Cloud
Cloud infrastructure is shared by multiple organizations and supports communities that
have shared concerns.
Private Cloud
Cloud infrastructure that is operated only for an enterprise [12].

Save on investment costs
Save time
Easier operations and management
Improve data availability and availability
Save operational costs [14].
Disadvantages of Cloud Computing
Internet connection, if the internet has problems, the computer will not be able to be
used to access the cloud so adequate and stable bandwidth is needed,
Companies that rent cloud computing services do not have direct access to resources.
If the service provider's server is damaged or the backup is poor, the company will
suffer losses [15].
Conclusion
Cloud computing is a combination of utilizing computing technology with flexible
internet-based development that can be used anytime, anywhere and on any device.
The development of cloud computing today really needs to be guided by an increase
in its security system, to control and minimize data theft or other cybercrime which is
currently still rampant.
Therefore, research on information security in cloud computing must certainly
continue to be developed, because cloud computing will be very useful and facilitate work for
general users and large companies.
Cloud Computing Discussion
There are many opinions about cloud computing. Many opinions think of the cloud as
a collection of technologies. It is true that there is a set of technologies that usually make up a
cloud environment, but these technologies are not the core of the cloud (Rountree, Derrick;
Castrillo, 2014). Cloud computing is a model for delivering information technology services
provided to users in a flexible manner, virtual servers, large scalability, and service
management. These information technology services can be used by organizations to operate
their business which can facilitate their users (Sullivan, 2009).
Cloud computing means storing and accessing data and programs over the internet
from a remote location using a computer. In order to be considered cloud computing, it is
necessary to access data or programs via the internet. The end result is the same however,
with an internet connection cloud computing can be done anywhere, anytime, and by any
device (K. Chandrasekaran, 2018. Chandrasekaran, 2018. Cloud computing is a new trend in
the field of distributed computing where various parties can develop SOA (Service Oriented
Architecture) based applications and services on the internet network (Herwin, 2011) [7].
Buyya et al. (2009) described cloud computing as the fifth utility along with water,
gas, electricity and telephone. Cloud computing includes on-demand available access to other
utility computing services [8].
According to Laudon and Loudon (2015), cloud computing is a computing mode
where processing activities, storage, software and other services are provided like an
integrated virtual source on a network which is generally the internet. The computing
resources of cloud computing are dispersed and can be accessed based on needs [9].
Cloud Computing Services
The type of user cloud computing service refers to the requirements and objectives of
the cloud computing used. Three types of cloud service models are commonly provided,
namely Infrastructure as a Service (IaaS) which is commonly used by system admins or
network architects, Platform as a Service (PaaS) which is commonly used by developers, and
Software as a Service (SaaS) which is commonly used by users.
Software as a Service (SaaS) provides software resource services that are hosted on
cloud servers. Platform as a Service (PaaS) provides platform access infrastructure, which
allows its own software to be deployed with other applications in the cloud. Infrastructure as
a Service (IaaS) provides services for customers to rent servers for computing, storage, and
network connectivity [10].
Cloud Computing Characteristics
Cloud computing has several characteristics, including (Marks, 2010):
Scalable (Aggregate)
Cloud computing has the ability to provide needs according to user demand.
Elastic
Cloud computing has the ability to increase or lower the operational power of the
application being used.
Self-service on demand
Application requirements are tailored to user requests.
Ubiquitous access
Capabilities that can be accessed from anywhere and using any device or application.
Complete virtualization
The ability to work across multiple infrastructures is known as virtualization to support
ubiquitous capabilities.
Relative consistency
Supports virtualization technology so that it can save costs in the use of information
technology.
Commodity
Being a major requirement in the provision of information technology devices or
allowing more tenants for an application [11].
Cloud Computing Deployment Model
The cloud computing deployment model is divided into four by NIST (2011), namely:
Hybrid Cloud
A composition of two or more clouds (private, community or public) whose entities are
unique but bound together by standards or technology ownership that use data and
application portability.
Public Cloud
Cloud infrastructure is available to the public or a large group that belongs to an
organization.
Community Cloud
Cloud infrastructure is shared by multiple organizations and supports communities that
have shared concerns.
Private Cloud
Cloud infrastructure that is operated only for an enterprise [12].
Cloud Computing Security Threats
According to the Cloud Security Alliance journal, there are 9 top threats that can occur in
cloud computing, including:
Data Breaches
Unauthorized viewing, accessing or retrieving of data by individuals, apps or services.
Configuration Error
Increased vulnerability to data breaches, caused by complex environments.
Insecure Interfaces and Application Programming Interfaces (APIs)
Cloud services depend on these APIs, so they must have secure certification standards,
and controls to avoid threats.
DDOS (Distributed Denial Of Services)
DDoS attacks are called bots or zombies that can be controlled remotely. The
controlled bots are called botnets, which send large requests to the server. As a result,
the server is flooded with requests and unprepared.
Account Hijacking
Attackers can access the system so that they can steal data or manipulate data that can
harm the company.
Malicious Insider
Employees who work inside and commit several crimes such as misuse of user
information.
Insufficient Due Diligence
Organizations that directly accept service offerings from service providers, without
sufficient knowledge.
Abusive Use of Cloud Services
Unethical and illegal actions from consumers by misusing services.
Shared Technology Issues
Occurs in multi-tenant, where services are provided using shared infrastructure so that
different users have access to the same VM (virtual machine) [13].
Pros of Cloud Computing in Business
Some of the advantages of Cloud Computing (Ashari, & Setiawan, 2011) (Fardani, &
Surendro, 2011) (Anik, 2013) (Singh, & Hemalatha, 2012) (Achmad, & Paulus, 2015)

from a remote location using a computer. In order to be considered cloud computing, it is
necessary to access data or programs via the internet. The end result is the same however,
with an internet connection cloud computing can be done anywhere, anytime, and by any
device (K. Chandrasekaran, 2018. Chandrasekaran, 2018. Cloud computing is a new trend in
the field of distributed computing where various parties can develop SOA (Service Oriented
Architecture) based applications and services on the internet network (Herwin, 2011) [7].
Buyya et al. (2009) described cloud computing as the fifth utility along with water,
gas, electricity and telephone. Cloud computing includes on-demand available access to other
utility computing services [8].
According to Laudon and Loudon (2015), cloud computing is a computing mode
where processing activities, storage, software and other services are provided like an
integrated virtual source on a network which is generally the internet. The computing
resources of cloud computing are dispersed and can be accessed based on needs [9].
Cloud Computing Services
The type of user cloud computing service refers to the requirements and objectives of
the cloud computing used. Three types of cloud service models are commonly provided,
namely Infrastructure as a Service (IaaS) which is commonly used by system admins or
network architects, Platform as a Service (PaaS) which is commonly used by developers, and
Software as a Service (SaaS) which is commonly used by users.
Software as a Service (SaaS) provides software resource services that are hosted on
cloud servers. Platform as a Service (PaaS) provides platform access infrastructure, which
allows its own software to be deployed with other applications in the cloud. Infrastructure as
a Service (IaaS) provides services for customers to rent servers for computing, storage, and
network connectivity [10].
Cloud Computing Characteristics
Cloud computing has several characteristics, including (Marks, 2010):
Scalable (Aggregate)
Cloud computing has the ability to provide needs according to user demand.
Elastic
Cloud computing has the ability to increase or lower the operational power of the
application being used.
Self-service on demand
Application requirements are tailored to user requests.
Ubiquitous access
Capabilities that can be accessed from anywhere and using any device or application.
Complete virtualization
The ability to work across multiple infrastructures is known as virtualization to support
ubiquitous capabilities.
Relative consistency
Supports virtualization technology so that it can save costs in the use of information
technology.
Commodity
Being a major requirement in the provision of information technology devices or
allowing more tenants for an application [11].
Cloud Computing Deployment Model
The cloud computing deployment model is divided into four by NIST (2011), namely:
Hybrid Cloud
A composition of two or more clouds (private, community or public) whose entities are
unique but bound together by standards or technology ownership that use data and
application portability.
Public Cloud
Cloud infrastructure is available to the public or a large group that belongs to an
organization.
Community Cloud
Cloud infrastructure is shared by multiple organizations and supports communities that
have shared concerns.
Private Cloud
Cloud infrastructure that is operated only for an enterprise [12].
Cloud Computing Security Threats
According to the Cloud Security Alliance journal, there are 9 top threats that can occur in
cloud computing, including:
Data Breaches
Unauthorized viewing, accessing or retrieving of data by individuals, apps or services.
Configuration Error
Increased vulnerability to data breaches, caused by complex environments.
Insecure Interfaces and Application Programming Interfaces (APIs)
Cloud services depend on these APIs, so they must have secure certification standards,
and controls to avoid threats.
DDOS (Distributed Denial Of Services)
DDoS attacks are called bots or zombies that can be controlled remotely. The
controlled bots are called botnets, which send large requests to the server. As a result,
the server is flooded with requests and unprepared.
Account Hijacking
Attackers can access the system so that they can steal data or manipulate data that can
harm the company.
Malicious Insider
Employees who work inside and commit several crimes such as misuse of user
information.
Insufficient Due Diligence
Organizations that directly accept service offerings from service providers, without
sufficient knowledge.
Abusive Use of Cloud Services
Unethical and illegal actions from consumers by misusing services.
Shared Technology Issues
Occurs in multi-tenant, where services are provided using shared infrastructure so that
different users have access to the same VM (virtual machine) [13].
Pros of Cloud Computing in Business
Some of the advantages of Cloud Computing (Ashari, & Setiawan, 2011) (Fardani, &
Surendro, 2011) (Anik, 2013) (Singh, & Hemalatha, 2012) (Achmad, & Paulus, 2015)
(Warjiyono, 2014), including:
Save on investment costs
Save time
Easier operations and management
Improve data availability and availability
Save operational costs [14].
Disadvantages of Cloud Computing
Internet connection, if the internet has problems, the computer will not be able to be
used to access the cloud so adequate and stable bandwidth is needed,
Companies that rent cloud computing services do not have direct access to resources.
If the service provider's server is damaged or the backup is poor, the company will
suffer losses [15].
Conclusion
Cloud computing is a combination of utilizing computing technology with flexible
internet-based development that can be used anytime, anywhere and on any device.
The development of cloud computing today really needs to be guided by an increase
in its security system, to control and minimize data theft or other cybercrime which is
currently still rampant.
Therefore, research on information security in cloud computing must certainly
continue to be developed, because cloud computing will be very useful and facilitate work for
general users and large companies.

a Service (IaaS) provides services for customers to rent servers for computing, storage, and
network connectivity [10].
Cloud Computing Characteristics
Cloud computing has several characteristics, including (Marks, 2010):
Scalable (Aggregate)
Cloud computing has the ability to provide needs according to user demand.
Elastic
Cloud computing has the ability to increase or lower the operational power of the
application being used.
Self-service on demand
Application requirements are tailored to user requests.
Ubiquitous access
Capabilities that can be accessed from anywhere and using any device or application.
Complete virtualization
The ability to work across multiple infrastructures is known as virtualization to support
ubiquitous capabilities.
Relative consistency
Supports virtualization technology so that it can save costs in the use of information
technology.
Commodity
Being a major requirement in the provision of information technology devices or
allowing more tenants for an application [11].
Cloud Computing Deployment Model
The cloud computing deployment model is divided into four by NIST (2011), namely:
Hybrid Cloud
A composition of two or more clouds (private, community or public) whose entities are
unique but bound together by standards or technology ownership that use data and
application portability.
Public Cloud
Cloud infrastructure is available to the public or a large group that belongs to an
organization.
Community Cloud
Cloud infrastructure is shared by multiple organizations and supports communities that
have shared concerns.
Private Cloud
Cloud infrastructure that is operated only for an enterprise [12].
Cloud Computing Security Threats
According to the Cloud Security Alliance journal, there are 9 top threats that can occur in
cloud computing, including:
Data Breaches
Unauthorized viewing, accessing or retrieving of data by individuals, apps or services.
Configuration Error
Increased vulnerability to data breaches, caused by complex environments.
Insecure Interfaces and Application Programming Interfaces (APIs)
Cloud services depend on these APIs, so they must have secure certification standards,
and controls to avoid threats.
DDOS (Distributed Denial Of Services)
DDoS attacks are called bots or zombies that can be controlled remotely. The
controlled bots are called botnets, which send large requests to the server. As a result,
the server is flooded with requests and unprepared.
Account Hijacking
Attackers can access the system so that they can steal data or manipulate data that can
harm the company.
Malicious Insider
Employees who work inside and commit several crimes such as misuse of user
information.
Insufficient Due Diligence
Organizations that directly accept service offerings from service providers, without
sufficient knowledge.
Abusive Use of Cloud Services
Unethical and illegal actions from consumers by misusing services.
Shared Technology Issues
Occurs in multi-tenant, where services are provided using shared infrastructure so that
different users have access to the same VM (virtual machine) [13].
Pros of Cloud Computing in Business
Some of the advantages of Cloud Computing (Ashari, & Setiawan, 2011) (Fardani, &
Surendro, 2011) (Anik, 2013) (Singh, & Hemalatha, 2012) (Achmad, & Paulus, 2015)
(Warjiyono, 2014), including:
Save on investment costs
Save time
Easier operations and management
Improve data availability and availability
Save operational costs [14].
Disadvantages of Cloud Computing
Internet connection, if the internet has problems, the computer will not be able to be
used to access the cloud so adequate and stable bandwidth is needed,
Companies that rent cloud computing services do not have direct access to resources.
If the service provider's server is damaged or the backup is poor, the company will
suffer losses [15].
Conclusion
Cloud computing is a combination of utilizing computing technology with flexible
internet-based development that can be used anytime, anywhere and on any device.
The development of cloud computing today really needs to be guided by an increase
in its security system, to control and minimize data theft or other cybercrime which is
currently still rampant.
Therefore, research on information security in cloud computing must certainly
continue to be developed, because cloud computing will be very useful and facilitate work for
general users and large companies.
Cloud Computing Discussion
There are many opinions about cloud computing. Many opinions think of the cloud as
a collection of technologies. It is true that there is a set of technologies that usually make up a
cloud environment, but these technologies are not the core of the cloud (Rountree, Derrick;
Castrillo, 2014). Cloud computing is a model for delivering information technology services
provided to users in a flexible manner, virtual servers, large scalability, and service
management. These information technology services can be used by organizations to operate
their business which can facilitate their users (Sullivan, 2009).
Cloud computing means storing and accessing data and programs over the internet
from a remote location using a computer. In order to be considered cloud computing, it is
necessary to access data or programs via the internet. The end result is the same however,
with an internet connection cloud computing can be done anywhere, anytime, and by any
device (K. Chandrasekaran, 2018. Chandrasekaran, 2018. Cloud computing is a new trend in
the field of distributed computing where various parties can develop SOA (Service Oriented
Architecture) based applications and services on the internet network (Herwin, 2011) [7].
Buyya et al. (2009) described cloud computing as the fifth utility along with water,
gas, electricity and telephone. Cloud computing includes on-demand available access to other
utility computing services [8].
According to Laudon and Loudon (2015), cloud computing is a computing mode
where processing activities, storage, software and other services are provided like an
integrated virtual source on a network which is generally the internet. The computing
resources of cloud computing are dispersed and can be accessed based on needs [9].
Cloud Computing Services
The type of user cloud computing service refers to the requirements and objectives of
the cloud computing used. Three types of cloud service models are commonly provided,
namely Infrastructure as a Service (IaaS) which is commonly used by system admins or
network architects, Platform as a Service (PaaS) which is commonly used by developers, and
Software as a Service (SaaS) which is commonly used by users.
Software as a Service (SaaS) provides software resource services that are hosted on
cloud servers. Platform as a Service (PaaS) provides platform access infrastructure, which
allows its own software to be deployed with other applications in the cloud. Infrastructure as
a Service (IaaS) provides services for customers to rent servers for computing, storage, and
network connectivity [10].

Increased vulnerability to data breaches, caused by complex environments.
Insecure Interfaces and Application Programming Interfaces (APIs)
Cloud services depend on these APIs, so they must have secure certification standards,
and controls to avoid threats.
DDOS (Distributed Denial Of Services)
DDoS attacks are called bots or zombies that can be controlled remotely. The
controlled bots are called botnets, which send large requests to the server. As a result,
the server is flooded with requests and unprepared.
Account Hijacking
Attackers can access the system so that they can steal data or manipulate data that can
harm the company.
Malicious Insider
Employees who work inside and commit several crimes such as misuse of user
information.
Insufficient Due Diligence
Organizations that directly accept service offerings from service providers, without
sufficient knowledge.
Abusive Use of Cloud Services
Unethical and illegal actions from consumers by misusing services.
Shared Technology Issues
Occurs in multi-tenant, where services are provided using shared infrastructure so that
different users have access to the same VM (virtual machine) [13].
Pros of Cloud Computing in Business
Some of the advantages of Cloud Computing (Ashari, & Setiawan, 2011) (Fardani, &
Surendro, 2011) (Anik, 2013) (Singh, & Hemalatha, 2012) (Achmad, & Paulus, 2015)
(Warjiyono, 2014), including:
Save on investment costs
Save time
Easier operations and management
Improve data availability and availability
Save operational costs [14].
Disadvantages of Cloud Computing
Internet connection, if the internet has problems, the computer will not be able to be
used to access the cloud so adequate and stable bandwidth is needed,
Companies that rent cloud computing services do not have direct access to resources.
If the service provider's server is damaged or the backup is poor, the company will
suffer losses [15].
Conclusion
Cloud computing is a combination of utilizing computing technology with flexible
internet-based development that can be used anytime, anywhere and on any device.
The development of cloud computing today really needs to be guided by an increase
in its security system, to control and minimize data theft or other cybercrime which is
currently still rampant.
Therefore, research on information security in cloud computing must certainly
continue to be developed, because cloud computing will be very useful and facilitate work for
general users and large companies.
Cloud Computing Discussion
There are many opinions about cloud computing. Many opinions think of the cloud as
a collection of technologies. It is true that there is a set of technologies that usually make up a
cloud environment, but these technologies are not the core of the cloud (Rountree, Derrick;
Castrillo, 2014). Cloud computing is a model for delivering information technology services
provided to users in a flexible manner, virtual servers, large scalability, and service
management. These information technology services can be used by organizations to operate
their business which can facilitate their users (Sullivan, 2009).
Cloud computing means storing and accessing data and programs over the internet
from a remote location using a computer. In order to be considered cloud computing, it is
necessary to access data or programs via the internet. The end result is the same however,
with an internet connection cloud computing can be done anywhere, anytime, and by any
device (K. Chandrasekaran, 2018. Chandrasekaran, 2018. Cloud computing is a new trend in
the field of distributed computing where various parties can develop SOA (Service Oriented
Architecture) based applications and services on the internet network (Herwin, 2011) [7].
Buyya et al. (2009) described cloud computing as the fifth utility along with water,
gas, electricity and telephone. Cloud computing includes on-demand available access to other
utility computing services [8].
According to Laudon and Loudon (2015), cloud computing is a computing mode
where processing activities, storage, software and other services are provided like an
integrated virtual source on a network which is generally the internet. The computing
resources of cloud computing are dispersed and can be accessed based on needs [9].
Cloud Computing Services
The type of user cloud computing service refers to the requirements and objectives of
the cloud computing used. Three types of cloud service models are commonly provided,
namely Infrastructure as a Service (IaaS) which is commonly used by system admins or
network architects, Platform as a Service (PaaS) which is commonly used by developers, and
Software as a Service (SaaS) which is commonly used by users.
Software as a Service (SaaS) provides software resource services that are hosted on
cloud servers. Platform as a Service (PaaS) provides platform access infrastructure, which
allows its own software to be deployed with other applications in the cloud. Infrastructure as
a Service (IaaS) provides services for customers to rent servers for computing, storage, and
network connectivity [10].
Cloud Computing Characteristics
Cloud computing has several characteristics, including (Marks, 2010):
Scalable (Aggregate)
Cloud computing has the ability to provide needs according to user demand.
Elastic
Cloud computing has the ability to increase or lower the operational power of the
application being used.
Self-service on demand
Application requirements are tailored to user requests.
Ubiquitous access
Capabilities that can be accessed from anywhere and using any device or application.
Complete virtualization
The ability to work across multiple infrastructures is known as virtualization to support
ubiquitous capabilities.
Relative consistency
Supports virtualization technology so that it can save costs in the use of information
technology.
Commodity
Being a major requirement in the provision of information technology devices or
allowing more tenants for an application [11].
Cloud Computing Deployment Model
The cloud computing deployment model is divided into four by NIST (2011), namely:
Hybrid Cloud
A composition of two or more clouds (private, community or public) whose entities are
unique but bound together by standards or technology ownership that use data and
application portability.
Public Cloud
Cloud infrastructure is available to the public or a large group that belongs to an
organization.
Community Cloud
Cloud infrastructure is shared by multiple organizations and supports communities that
have shared concerns.
Private Cloud
Cloud infrastructure that is operated only for an enterprise [12].
Cloud Computing Security Threats
According to the Cloud Security Alliance journal, there are 9 top threats that can occur in
cloud computing, including:
Data Breaches
Unauthorized viewing, accessing or retrieving of data by individuals, apps or services.

Companies that rent cloud computing services do not have direct access to resources.
If the service provider's server is damaged or the backup is poor, the company will
suffer losses [15].
Conclusion
Cloud computing is a combination of utilizing computing technology with flexible
internet-based development that can be used anytime, anywhere and on any device.
The development of cloud computing today really needs to be guided by an increase
in its security system, to control and minimize data theft or other cybercrime which is
currently still rampant.
Therefore, research on information security in cloud computing must certainly
continue to be developed, because cloud computing will be very useful and facilitate work for
general users and large companies.
Cloud Computing Discussion
There are many opinions about cloud computing. Many opinions think of the cloud as
a collection of technologies. It is true that there is a set of technologies that usually make up a
cloud environment, but these technologies are not the core of the cloud (Rountree, Derrick;
Castrillo, 2014). Cloud computing is a model for delivering information technology services
provided to users in a flexible manner, virtual servers, large scalability, and service
management. These information technology services can be used by organizations to operate
their business which can facilitate their users (Sullivan, 2009).
Cloud computing means storing and accessing data and programs over the internet
from a remote location using a computer. In order to be considered cloud computing, it is
necessary to access data or programs via the internet. The end result is the same however,
with an internet connection cloud computing can be done anywhere, anytime, and by any
device (K. Chandrasekaran, 2018. Chandrasekaran, 2018. Cloud computing is a new trend in
the field of distributed computing where various parties can develop SOA (Service Oriented
Architecture) based applications and services on the internet network (Herwin, 2011) [7].
Buyya et al. (2009) described cloud computing as the fifth utility along with water,
gas, electricity and telephone. Cloud computing includes on-demand available access to other
utility computing services [8].
According to Laudon and Loudon (2015), cloud computing is a computing mode
where processing activities, storage, software and other services are provided like an
integrated virtual source on a network which is generally the internet. The computing
resources of cloud computing are dispersed and can be accessed based on needs [9].
Cloud Computing Services
The type of user cloud computing service refers to the requirements and objectives of
the cloud computing used. Three types of cloud service models are commonly provided,
namely Infrastructure as a Service (IaaS) which is commonly used by system admins or
network architects, Platform as a Service (PaaS) which is commonly used by developers, and
Software as a Service (SaaS) which is commonly used by users.
Software as a Service (SaaS) provides software resource services that are hosted on
cloud servers. Platform as a Service (PaaS) provides platform access infrastructure, which
allows its own software to be deployed with other applications in the cloud. Infrastructure as
a Service (IaaS) provides services for customers to rent servers for computing, storage, and
network connectivity [10].
Cloud Computing Characteristics
Cloud computing has several characteristics, including (Marks, 2010):
Scalable (Aggregate)
Cloud computing has the ability to provide needs according to user demand.
Elastic
Cloud computing has the ability to increase or lower the operational power of the
application being used.
Self-service on demand
Application requirements are tailored to user requests.
Ubiquitous access
Capabilities that can be accessed from anywhere and using any device or application.
Complete virtualization
The ability to work across multiple infrastructures is known as virtualization to support
ubiquitous capabilities.
Relative consistency
Supports virtualization technology so that it can save costs in the use of information
technology.
Commodity
Being a major requirement in the provision of information technology devices or
allowing more tenants for an application [11].
Cloud Computing Deployment Model
The cloud computing deployment model is divided into four by NIST (2011), namely:
Hybrid Cloud
A composition of two or more clouds (private, community or public) whose entities are
unique but bound together by standards or technology ownership that use data and
application portability.
Public Cloud
Cloud infrastructure is available to the public or a large group that belongs to an
organization.
Community Cloud
Cloud infrastructure is shared by multiple organizations and supports communities that
have shared concerns.
Private Cloud
Cloud infrastructure that is operated only for an enterprise [12].
Cloud Computing Security Threats
According to the Cloud Security Alliance journal, there are 9 top threats that can occur in
cloud computing, including:
Data Breaches
Unauthorized viewing, accessing or retrieving of data by individuals, apps or services.
Configuration Error
Increased vulnerability to data breaches, caused by complex environments.
Insecure Interfaces and Application Programming Interfaces (APIs)
Cloud services depend on these APIs, so they must have secure certification standards,
and controls to avoid threats.
DDOS (Distributed Denial Of Services)
DDoS attacks are called bots or zombies that can be controlled remotely. The
controlled bots are called botnets, which send large requests to the server. As a result,
the server is flooded with requests and unprepared.
Account Hijacking
Attackers can access the system so that they can steal data or manipulate data that can
harm the company.
Malicious Insider
Employees who work inside and commit several crimes such as misuse of user
information.
Insufficient Due Diligence
Organizations that directly accept service offerings from service providers, without
sufficient knowledge.
Abusive Use of Cloud Services
Unethical and illegal actions from consumers by misusing services.
Shared Technology Issues
Occurs in multi-tenant, where services are provided using shared infrastructure so that
different users have access to the same VM (virtual machine) [13].
Pros of Cloud Computing in Business
Some of the advantages of Cloud Computing (Ashari, & Setiawan, 2011) (Fardani, &
Surendro, 2011) (Anik, 2013) (Singh, & Hemalatha, 2012) (Achmad, & Paulus, 2015)
(Warjiyono, 2014), including:
Save on investment costs
Save time
Easier operations and management
Improve data availability and availability
Save operational costs [14].
Disadvantages of Cloud Computing

Architecture) based applications and services on the internet network (Herwin, 2011) [7].
Buyya et al. (2009) described cloud computing as the fifth utility along with water,
gas, electricity and telephone. Cloud computing includes on-demand available access to other
utility computing services [8].
According to Laudon and Loudon (2015), cloud computing is a computing mode
where processing activities, storage, software and other services are provided like an
integrated virtual source on a network which is generally the internet. The computing
resources of cloud computing are dispersed and can be accessed based on needs [9].
Cloud Computing Services
The type of user cloud computing service refers to the requirements and objectives of
the cloud computing used. Three types of cloud service models are commonly provided,
namely Infrastructure as a Service (IaaS) which is commonly used by system admins or
network architects, Platform as a Service (PaaS) which is commonly used by developers, and
Software as a Service (SaaS) which is commonly used by users.
Software as a Service (SaaS) provides software resource services that are hosted on
cloud servers. Platform as a Service (PaaS) provides platform access infrastructure, which
allows its own software to be deployed with other applications in the cloud. Infrastructure as
a Service (IaaS) provides services for customers to rent servers for computing, storage, and
network connectivity [10].
Cloud Computing Characteristics
Cloud computing has several characteristics, including (Marks, 2010):
Scalable (Aggregate)
Cloud computing has the ability to provide needs according to user demand.
Elastic
Cloud computing has the ability to increase or lower the operational power of the
application being used.
Self-service on demand
Application requirements are tailored to user requests.
Ubiquitous access
Capabilities that can be accessed from anywhere and using any device or application.
Complete virtualization
The ability to work across multiple infrastructures is known as virtualization to support
ubiquitous capabilities.
Relative consistency
Supports virtualization technology so that it can save costs in the use of information
technology.
Commodity
Being a major requirement in the provision of information technology devices or
allowing more tenants for an application [11].
Cloud Computing Deployment Model
The cloud computing deployment model is divided into four by NIST (2011), namely:
Hybrid Cloud
A composition of two or more clouds (private, community or public) whose entities are
unique but bound together by standards or technology ownership that use data and
application portability.
Public Cloud
Cloud infrastructure is available to the public or a large group that belongs to an
organization.
Community Cloud
Cloud infrastructure is shared by multiple organizations and supports communities that
have shared concerns.
Private Cloud
Cloud infrastructure that is operated only for an enterprise [12].
Cloud Computing Security Threats
According to the Cloud Security Alliance journal, there are 9 top threats that can occur in
cloud computing, including:
Data Breaches
Unauthorized viewing, accessing or retrieving of data by individuals, apps or services.
Configuration Error
Increased vulnerability to data breaches, caused by complex environments.
Insecure Interfaces and Application Programming Interfaces (APIs)
Cloud services depend on these APIs, so they must have secure certification standards,
and controls to avoid threats.
DDOS (Distributed Denial Of Services)
DDoS attacks are called bots or zombies that can be controlled remotely. The
controlled bots are called botnets, which send large requests to the server. As a result,
the server is flooded with requests and unprepared.
Account Hijacking
Attackers can access the system so that they can steal data or manipulate data that can
harm the company.
Malicious Insider
Employees who work inside and commit several crimes such as misuse of user
information.
Insufficient Due Diligence
Organizations that directly accept service offerings from service providers, without
sufficient knowledge.
Abusive Use of Cloud Services
Unethical and illegal actions from consumers by misusing services.
Shared Technology Issues
Occurs in multi-tenant, where services are provided using shared infrastructure so that
different users have access to the same VM (virtual machine) [13].
Pros of Cloud Computing in Business
Some of the advantages of Cloud Computing (Ashari, & Setiawan, 2011) (Fardani, &
Surendro, 2011) (Anik, 2013) (Singh, & Hemalatha, 2012) (Achmad, & Paulus, 2015)
(Warjiyono, 2014), including:
Save on investment costs
Save time
Easier operations and management
Improve data availability and availability
Save operational costs [14].
Disadvantages of Cloud Computing
Internet connection, if the internet has problems, the computer will not be able to be
used to access the cloud so adequate and stable bandwidth is needed,
Companies that rent cloud computing services do not have direct access to resources.
If the service provider's server is damaged or the backup is poor, the company will
suffer losses [15].
Conclusion
Cloud computing is a combination of utilizing computing technology with flexible
internet-based development that can be used anytime, anywhere and on any device.
The development of cloud computing today really needs to be guided by an increase
in its security system, to control and minimize data theft or other cybercrime which is
currently still rampant.
Therefore, research on information security in cloud computing must certainly
continue to be developed, because cloud computing will be very useful and facilitate work for
general users and large companies.
Cloud Computing Discussion
There are many opinions about cloud computing. Many opinions think of the cloud as
a collection of technologies. It is true that there is a set of technologies that usually make up a
cloud environment, but these technologies are not the core of the cloud (Rountree, Derrick;
Castrillo, 2014). Cloud computing is a model for delivering information technology services
provided to users in a flexible manner, virtual servers, large scalability, and service
management. These information technology services can be used by organizations to operate
their business which can facilitate their users (Sullivan, 2009).
Cloud computing means storing and accessing data and programs over the internet
from a remote location using a computer. In order to be considered cloud computing, it is
necessary to access data or programs via the internet. The end result is the same however,
with an internet connection cloud computing can be done anywhere, anytime, and by any
device (K. Chandrasekaran, 2018. Chandrasekaran, 2018. Cloud computing is a new trend in
the field of distributed computing where various parties can develop SOA (Service Oriented

Application requirements are tailored to user requests.
Ubiquitous access
Capabilities that can be accessed from anywhere and using any device or application.
Complete virtualization
The ability to work across multiple infrastructures is known as virtualization to support
ubiquitous capabilities.
Relative consistency
Supports virtualization technology so that it can save costs in the use of information
technology.
Commodity
Being a major requirement in the provision of information technology devices or
allowing more tenants for an application [11].
Cloud Computing Deployment Model
The cloud computing deployment model is divided into four by NIST (2011), namely:
Hybrid Cloud
A composition of two or more clouds (private, community or public) whose entities are
unique but bound together by standards or technology ownership that use data and
application portability.
Public Cloud
Cloud infrastructure is available to the public or a large group that belongs to an
organization.
Community Cloud
Cloud infrastructure is shared by multiple organizations and supports communities that
have shared concerns.
Private Cloud
Cloud infrastructure that is operated only for an enterprise [12].
Cloud Computing Security Threats
According to the Cloud Security Alliance journal, there are 9 top threats that can occur in
cloud computing, including:
Data Breaches
Unauthorized viewing, accessing or retrieving of data by individuals, apps or services.
Configuration Error
Increased vulnerability to data breaches, caused by complex environments.
Insecure Interfaces and Application Programming Interfaces (APIs)
Cloud services depend on these APIs, so they must have secure certification standards,
and controls to avoid threats.
DDOS (Distributed Denial Of Services)
DDoS attacks are called bots or zombies that can be controlled remotely. The
controlled bots are called botnets, which send large requests to the server. As a result,
the server is flooded with requests and unprepared.
Account Hijacking
Attackers can access the system so that they can steal data or manipulate data that can
harm the company.
Malicious Insider
Employees who work inside and commit several crimes such as misuse of user
information.
Insufficient Due Diligence
Organizations that directly accept service offerings from service providers, without
sufficient knowledge.
Abusive Use of Cloud Services
Unethical and illegal actions from consumers by misusing services.
Shared Technology Issues
Occurs in multi-tenant, where services are provided using shared infrastructure so that
different users have access to the same VM (virtual machine) [13].
Pros of Cloud Computing in Business
Some of the advantages of Cloud Computing (Ashari, & Setiawan, 2011) (Fardani, &
Surendro, 2011) (Anik, 2013) (Singh, & Hemalatha, 2012) (Achmad, & Paulus, 2015)
(Warjiyono, 2014), including:
Save on investment costs
Save time
Easier operations and management
Improve data availability and availability
Save operational costs [14].
Disadvantages of Cloud Computing
Internet connection, if the internet has problems, the computer will not be able to be
used to access the cloud so adequate and stable bandwidth is needed,
Companies that rent cloud computing services do not have direct access to resources.
If the service provider's server is damaged or the backup is poor, the company will
suffer losses [15].
Conclusion
Cloud computing is a combination of utilizing computing technology with flexible
internet-based development that can be used anytime, anywhere and on any device.
The development of cloud computing today really needs to be guided by an increase
in its security system, to control and minimize data theft or other cybercrime which is
currently still rampant.
Therefore, research on information security in cloud computing must certainly
continue to be developed, because cloud computing will be very useful and facilitate work for
general users and large companies.
Cloud Computing Discussion
There are many opinions about cloud computing. Many opinions think of the cloud as
a collection of technologies. It is true that there is a set of technologies that usually make up a
cloud environment, but these technologies are not the core of the cloud (Rountree, Derrick;
Castrillo, 2014). Cloud computing is a model for delivering information technology services
provided to users in a flexible manner, virtual servers, large scalability, and service
management. These information technology services can be used by organizations to operate
their business which can facilitate their users (Sullivan, 2009).
Cloud computing means storing and accessing data and programs over the internet
from a remote location using a computer. In order to be considered cloud computing, it is
necessary to access data or programs via the internet. The end result is the same however,
with an internet connection cloud computing can be done anywhere, anytime, and by any
device (K. Chandrasekaran, 2018. Chandrasekaran, 2018. Cloud computing is a new trend in
the field of distributed computing where various parties can develop SOA (Service Oriented
Architecture) based applications and services on the internet network (Herwin, 2011) [7].
Buyya et al. (2009) described cloud computing as the fifth utility along with water,
gas, electricity and telephone. Cloud computing includes on-demand available access to other
utility computing services [8].
According to Laudon and Loudon (2015), cloud computing is a computing mode
where processing activities, storage, software and other services are provided like an
integrated virtual source on a network which is generally the internet. The computing
resources of cloud computing are dispersed and can be accessed based on needs [9].
Cloud Computing Services
The type of user cloud computing service refers to the requirements and objectives of
the cloud computing used. Three types of cloud service models are commonly provided,
namely Infrastructure as a Service (IaaS) which is commonly used by system admins or
network architects, Platform as a Service (PaaS) which is commonly used by developers, and
Software as a Service (SaaS) which is commonly used by users.
Software as a Service (SaaS) provides software resource services that are hosted on
cloud servers. Platform as a Service (PaaS) provides platform access infrastructure, which
allows its own software to be deployed with other applications in the cloud. Infrastructure as
a Service (IaaS) provides services for customers to rent servers for computing, storage, and
network connectivity [10].
Cloud Computing Characteristics
Cloud computing has several characteristics, including (Marks, 2010):
Scalable (Aggregate)
Cloud computing has the ability to provide needs according to user demand.
Elastic
Cloud computing has the ability to increase or lower the operational power of the
application being used.
Self-service on demand
Application requirements are tailored to user requests.
Ubiquitous access
Capabilities that can be accessed from anywhere and using any device or application.
