Practical Cyber Hacking Skills for Beginners - The CIA and DAD Triads

The video tutorial introduces the CIA and DAD triads, fundamental concepts in cybersecurity. The CIA triad consists of confidentiality, integrity, and availability, which are essential for protecting data and resources. Confidentiality ensures only authorized access, integrity maintains data accuracy, and availability guarantees resource accessibility. The DAD triad represents the opposite threats: disclosure, alteration, and deniability. Disclosure involves unauthorized data access, alteration refers to data tampering, and deniability blocks access to resources. The tutorial emphasizes the importance of understanding these concepts for cybersecurity professionals.

What are the three fundamental pillars of cybersecurity known as the CIA triad?

• Confidentiality, Integrity, Authorization

• Confidentiality, Integrity, Authentication

• Confidentiality, Integrity, Availability

• Confidentiality, Integrity, Access

Which technology is primarily used to ensure confidentiality in cybersecurity?

• Checksums

• Network Access

• Hashing

• Encryption

What is the purpose of hashing in cybersecurity?

• To encrypt data

• To ensure data integrity

• To provide network access

• To authenticate users

In the DAD triad, what does 'disclosure' refer to?

• Data being unavailable

• Data being accessed by unauthorized users

• Data being altered

• Data being encrypted

Which of the following is an example of a threat to availability in the DAD triad?
