Question

In this assignment, you are requested to do thorough assessment to three important cybersecurity requirements, which discussed by the CIA model. Choose any of the organization real/ virtual and then answer the following question:

1) List and define all the cybersecurity requirements, proposed by CIA Model?
2) Explain the impact and the potential consequences when each specific identified elements of CIA is lost? Give examples to each elements
3) Explain methods of control that organization can use and it is applicable to the corresponding CIA elements lost requirements. Give examples
4) Search the special publication (NIST SP 800-53" provide overview on the standard catalog of security controls requirements that address all aspects of cybersecurity?

Answer 1

The CIA model in cybersecurity includes confidentiality, integrity, and availability, which are integral to data protection. The loss of any of these elements can have severe consequences, such as data breaches, data tampering, and service disruptions. To mitigate these risks, organizations can utilize encryption, AIDs, redundant systems, and follow NIST SP 800-53 guidelines.

Step-by-step explanation:

Cybersecurity Requirements of the CIA Model. The CIA model in cybersecurity stands for confidentiality, integrity, and availability, which are the cornerstone principles for protecting data. Confidentiality ensures that sensitive information is accessed only by authorized individuals. Integrity refers to maintaining the accuracy and completeness of data and ensuring that it is not tampered with. Availability ensures that data and services are available to authorized users when needed. Impact and Consequences of CIA Element Loss. Loss of confidentiality, such as through a data breach, can lead to the exposure of sensitive personal information, identity theft, and loss of public trust. Compromised integrity may result in incorrect decisions based on falsified data, financial losses, and legal implications. Lack of availability due to issues like DOS attacks can disrupt business operations, culminate in financial loss, and impact customer trust. Methods of Control for Protecting CIA Elements.

Organizations can implement encryption to protect confidentiality, checksums and access controls to maintain integrity, redundant systems, and regular updates to ensure availability. Encryption protects data in transit and at rest, making it unreadable to unauthorized users. Using AIDs (Authentication, Authorization, and Accounting) can further enhance data integrity, and maintaining infrastructure with failovers can enhance system availability. Overview of NIST SP 800-53. NIST SP 800-53 is a special publication that offers a comprehensive catalog of security controls for federal information systems and organizations, aiming to address all aspects of cybersecurity. It outlines controls and guidelines for implementing robust security postures to mitigate risks and protect against an array of cyber threats.
