The main uses for an IT system
Communication purposes-in collecting and distributing information, and the IT system can make the process to be more efficient
Operations Management-IT system offers more complete and more recent information.
Communication purposes
Part of management is gathering and distributing information, and the IT system can make this process more efficient by allowing Ben to communicate efficiently
Operations Management
IT system offers more complete and more recent information, allowing Ben to operate the company more efficiently. Ben can use information systems to gain a cost advantage over competitors or to differentiate himself by offering better customer service. Sales data give Ben insights about what customers are buying and let him provide better services that are selling well. With guidance from the information system, Ben can streamline his operations.
*
The main uses for an IT system
Decision-Making- the IT system can help Ben make better decisions by providing all the needed information
Record-Keeping- the shop requires records of its operations for financial and regulatory functions
Decision-Making
The company information system can help Ben make better decisions by delivering all the information he needs and by modeling the results of his decisions. When Ben has accurate, up-to-date information, he can make the choices with confidence
Record-Keeping
Your company needs records of its activities for financial and regulatory purposes as well as for finding the causes of problems and taking corrective action. The information system stores documents and revision histories, communication records and operational data

Data Types and Risks
All data should be classified into either one of the following
Restricted Data-Data whose unauthorized disclosure, modification or destruction could lead to high level of risk to the business e.g. data protected by state
Data classification based on its level of sensitivity and the impact to the business should that data be disclosed, altered or destroyed without authorization. The classification of data helps determine what baseline security controls are appropriate for safeguarding that data. All data should be classified into one of three classifications:
Restricted Data
Data should be classified as Restricted when the unauthorized disclosure, alteration or destruction of that data could cause a significant level of risk to the business or its affiliates. Examples of Restricted data include data protected by state or federal privacy regulations and data protected by confidentiality agreements.
*
Data Types and Risks
Private Data-Data whose unauthorized disclosure, modification or destruction could lead to moderate level of risk to the business .
Public Data-Data whose unauthorized disclosure, modification or destruction could lead to little or no risk to the business
Private Data
Data should be classified as Private when the unauthorized disclosure, alteration or destruction of that data could result in a moderate level of risk to the business or its affiliates.
Public Data
Data should be classified as Public when the unauthorized disclosure, alteration or destruction of that data would results in little or no risk to the business and its affiliates. While little or no controls are required to protect the confidentiality of Public data, some level of control is required to prevent unauthorized modification or destruction of Public data.
*

Risks Mitigation
The installation of reliable antivirus software
Utilization of complex passwords in each of the computers and Web-based applications
Provision of guidelines through employee training on dos and don’ts of utilizing systems and Internet.
Creation of security policy to addresses the responsibilities, rights and duties of employees
Risks Mitigation
The installation of reliable antivirus software which acts as the final line of defense from unwanted attacks. The antivirus program detects and removes virus and malware as well as filter possibly malicious downloads or emails.
All employees must utilize complex passwords in each of the computers and Web-based applications that require key for access. Complex passwords make it hard for hackers to crack them.
Installation of encryption software that protects data related to credit cards and bank accounts. Strong encryption algorithms transform readable data into unreadable codes that make altering of information difficult to accomplish. Even when data is lost it becomes obsolete without the keys used to encrypt the data.
Provision of guidelines through employee training on dos and don’ts of utilizing systems and Internet. For example, on how to handle suspicious emails. A security policy provides guidelines on putting limited access to critical data, taking of regular back-ups and the securing of Wi-Fi Networks that are highly vulnerable to attacks.
The security policy to addresses the responsibilities, rights and duties of employees

Information Security Policy
Benefits of Implementing Access control
- It increases safety
- Increases security of sensitive data
- Helps to reduce theft and accidents
- Account for incoming and outgoing individuals
- Curtails unwanted strangers
(Rittinghouse & Ransome, 2016)
Increases safety
it increases the safety of employees getting into the business. It becomes faster to swipe access cards and it is not easily duplicated by malicious persons.
Increases security of sensitive data
The employees with the required clearance are the only ones that are given access to the company’s sensitive data. through this, the company is able to regulate the number of people that have access to some data that is deemed sensitive to be disclosed to the competitors or the general public.
Reduce theft and accidents
The business will be able to give only approved employees the access to some designated areas. This makes usre that theft or accidents are greatly reduced.
Account for incoming and outgoing individuals
Each individual accessing the system should be accounted for as this will be useful in ensuring that their actions are always accounted. Some of them might access the systems with malicious intent which needs to be identified fast for the good of the company.
Curtail unwanted strangers
Access control denies unwanted strangers the ability to log into the company’s systems to cause havoc in them or steal confidential data.
*
Ways to use Authentication and Authorization to protect Company Data
- Single-factor and Multi-factor authentication
- Biometrics
- Federations
(Ting et al., 2015).
Single and multi-factor authentication
Single-factor and multi-factor authentication will require any employee to produce some credentials e.g. passwords or PINS as well as usernames before they can be granted access to the company’s data or information
Biometrics
it is one of the secure ways to implement access control. They include fingerprint scanners, full hand scanners, eye scanners, facial recognition and voice recognition. This will help protect company data and sensitive information from malicious persons
Federations
Set by a means of federated identity that links system users identity with their privileges and hence restricting from accessing data and information that is beyond their clearance.

How Temporary Employees Make Data Vulnerable To Social Engineering Works.
Temporary employees make data vulnerable due to various reasons;
- Lack of adequate knowledge about the working of the organization. This way the employees make the data vulnerable because they do not understand the threats facing the system (Berson, 2011).
- Some have malicious intentions and therefore expose data to social engineering works.
Vulnerabilities to Social Engineering works
Some employees have ill-intentions and therefore expose data to vulnerabilities. Such employees can distribute confidential information over the internet.
Ignorance among some of employees maybe harmful to an organization. Such employees may fail to follow important data security protocols which in turn exposes data to vulnerabilities.
*
Methods To Mitigate Social Engineering Threats
Ways of mitigating social engineering threats include;
Educating employees about securing their personal information that can be used for social engineering attacks.
Ensuring that the software in use is up-to date.
Establishing policies that protect confidential information from exposure (DeLuccia,2008).
Mitigating Social Engineering Threats
Most social engineering criminals tend to success due to ignorance among people. It is the responsibility of the organization to teach its employees about these attacks to prevent future attacks.
Criminals ten to exploit updated software when executing their attacks. It is therefore important for organizations to ensure that they software are always up to date.
Having a security policy is a step towards mitigating social engineering threats.
