9. What are the 5 concepts of cybersecurity?

The five core concepts, often expanding on the foundational CIA triad, are:

1. Confidentiality: Ensures that sensitive information is only accessible to authorized users.

2. Integrity: Ensures that data is accurate and has not been tampered with or modified by unauthorized parties.

3. Availability: Ensures that authorized users can access systems and data when needed, protecting against denial-of-service attacks and outages.

4. Authenticity: Verifies the identity of a user, system, or data source to ensure they are genuine.

5. Non-repudiation: Ensures that a party to a transaction or communication cannot deny that they sent or received it, providing legal accountability.
