Subject: Information on the cyber domain to determine organization's cybersecurity
needs
Cyber Domain
The cyber domain refers to the cyberspace that is the result of technological
advancement and evolution. It is the fifth domain after land, Air Sea and space that
has become a necessity in the 21st century. It is a human creation that is the result of
the continuous technological development. It has significant impact at the individual
level as well as at the organizational level (Efrony, 2019). It is the cyberspace that
exists within the information environment, encompassing of interdependent networks of
IT infrastructures along with the resident data, including the Internet, computer systems,
telecommunications network, as well as the embedded processors and controllers
(Crowther, 2017).
Key components and aspects of cybersecurity and its relation to the cyber domain
Cybersecurity is the safeguarding of the internet-connected systems like the
software, hardware and data from different kinds of cyber threats. This practice is
adopted by most of the organizations in the digitalized era so that the IT landscape of
the undertaking can be protected from any unauthorized access or malicious practice.
The key components that make up cybersecurity include application security,
information security, network security, and disaster recovery planning, operational
security and end-user education. Each of these components work together and help a
business entity to strengthen its IT posture and have an edge against cybercriminals
and online hackers (What are the Key Elements of CyberSecurity, 2020). The key
components of cybersecurity play a cardinal role for an organization in the vast cyber
domain and help to manage the uncertainty and threats that could affect the entity in
the domain. c
Approach for implementing information security for the organization
The bottom-up approach can be adopted for implementing information security
in the organization. It would be implemented by the system administrators and the
professionals who function in the network security arena (Lubell, 2016). The primary
purpose for choosing such an approach is to make the optimum use of the knowledge
of individuals who work in the field of information system. In the highly unpredictable
cyber domain the approach would be useful to design a secure cybersecurity model
that is in sync with the security needs of the organization. The bottom-up approach
could be further adopted in the broader cyber domain by integrating the new insight,
knowledge and expertise of the employees that work in the IT department of the
organization (Lubell, 2016).
Possible threats for the organization in the cyber domain
A diverse range of threats could arise before the organization in the cyber domain
that could negatively affect its Information Technology posture such as:
• Phishing – This threat is a fraudulent practice involving sending mails to induce
the revelation of sensitive and confidential data like passwords (Shi & Saleem,
2012).
• Botnets – These internet-connected devices could be used for performing the
Distributed Denial-of-Service (DDOS) attacks, steal data and give unauthorized
access to the attacker (Eslahi et al., 2012).
• Ransomware – This threat could gain unauthorized access to the IT system of
the entity and block the user access.
Such threats could compromise the cybersecurity of the firm in the cyber domain.
Sincerely,
Mr X,
IT Supervisor
