Three characteristics determine the reliability of information. Which characteristics are these?

Question

Options

• AAvailability, Integrity and Correctness
• BAvailability, Integrity and Confidentiality
• CAvailability, Nonrepudiation and Confidentiality

• A
  18% (5)
• B
  71% (20)
• C
  11% (3)

Explanation

B is correct because the three pillars of information reliability are Availability, Integrity, and Confidentiality - collectively known as the CIA triad, the foundational framework in information security.

Why the distractors fail:

• A (Correctness) is wrong because "Correctness" is not a standard security characteristic - it's a loose synonym for Integrity but not the recognized term; Confidentiality is the missing pillar here.
• C (Nonrepudiation) is wrong because nonrepudiation (ensuring actions can't be denied) is a related but separate security property - it doesn't replace Integrity in the core triad.

Memory tip: Use the acronym CIA - just like the spy agency that keeps secrets (Confidentiality), ensures information isn't tampered with (Integrity), and needs systems up and running (Availability).
