Understanding CIA Triad and Non-Repudiation

What does the 'C' in CIA Triad stand for?

• Confidentiality

• Integrity

• Accessibility

• Control

Explain the concept of 'Integrity' in the CIA Triad.

• Integrity focuses on the encryption of data.

• Integrity refers to the speed of data processing.

• Integrity is about ensuring data is easily accessible.

• Integrity ensures that data is accurate and unaltered, maintaining its trustworthiness.

What is meant by 'Availability' in the context of the CIA Triad?

• Availability means ensuring that information and resources are accessible to authorized users when needed.

• Availability refers to the confidentiality of sensitive information.

• Availability means ensuring data is encrypted at all times.

• Availability is about preventing unauthorized access to resources.

Define non-repudiation in information security.

• Non-repudiation is a security principle that prevents an entity from denying the authenticity of their actions or communications.

• Non-repudiation allows users to change their previous actions.

• Non-repudiation is a method to increase data storage capacity.

• Non-repudiation ensures data is always encrypted.

How does non-repudiation enhance trust in digital communications?

• Non-repudiation eliminates the risk of data breaches in digital communications.

• Non-repudiation enhances trust by providing proof of the authenticity and integrity of communications, ensuring accountability.

• Non-repudiation allows users to deny sending messages at any time.

• Non-repudiation reduces the need for encryption in communications.

What role does encryption play in ensuring non-repudiation?

• Encryption only protects data from unauthorized access.

• Encryption helps verify the sender's identity and message integrity, preventing denial of involvement.

• Encryption prevents all forms of data loss.

• Encryption is solely used for data storage security.

Can you provide an example of a non-repudiation mechanism?

• Digital signatures

• Encryption keys

• Antivirus software

• Firewalls

How does the CIA Triad relate to cybersecurity policies?

• The CIA Triad is a marketing strategy for cybersecurity companies.

• The CIA Triad is irrelevant to cybersecurity policies.

• The CIA Triad only focuses on physical security measures.

• The CIA Triad serves as a foundational framework for developing effective cybersecurity policies.

What are the potential consequences of failing to maintain the CIA Triad?

• Increased data storage capacity

• Enhanced user experience

• Improved system performance

• Data breaches, loss of sensitive information, unauthorized access, data corruption, service outages.

Discuss how non-repudiation can be achieved in online transactions.

• Non-repudiation can be achieved through digital signatures, secure logging, timestamps, and third-party verification.

• Implementing basic encryption without verification

• Relying solely on user agreements

• Using only passwords for authentication
