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
  13% (7)
• B
  79% (41)
• C
  8% (4)

Explanation

Option B is correct because the three pillars of information reliability (also known as the CIA Triad in information security) are Confidentiality (information is accessible only to authorized parties), Integrity (information is accurate and unaltered), and Availability (information is accessible when needed). Option A replaces Confidentiality with "Correctness," which is not a standard security characteristic - accuracy/correctness is actually part of Integrity, not a separate pillar. Option C replaces Integrity with "Nonrepudiation," which is a valid security concept (ensuring actions can't be denied) but is not one of the three core reliability characteristics. Memory tip: Use the acronym CIA - Confidentiality, Integrity, Availability - just like a secret agency that keeps things secret, accurate, and accessible.
