We can acquire and supply information in various ways. The value of the information depends on whether it is reliable. What are the reliability aspects of information?

Question

Options

• AAvailability, Information Value and Confidentiality
• BAvailability, Integrity and Confidentiality
• CAvailability, Integrity and Completeness
• DTimeliness, Accuracy and Completeness

• A
  7% (3)
• B
  76% (32)
• C
  12% (5)
• D
  5% (2)

Explanation

Option B is correct because the three core reliability aspects of information are Availability, Integrity, and Confidentiality - commonly known as the CIA Triad, the foundational model for information security and trustworthiness.

• Option A is wrong because "Information Value" is not a reliability aspect - it describes the worth of information, not whether it can be trusted or accessed securely.
• Option C is wrong because "Completeness" is a quality characteristic of data, but it is not one of the three standard reliability pillars; Confidentiality is the missing piece.
• Option D is wrong because Timeliness and Accuracy are data quality attributes, not the established reliability framework - they describe how good the information is, not how secure or reliable it is in a systemic sense.

Memory tip: Use the acronym CIA (like the agency that keeps things secret and secure) - Confidentiality, Integrity, Availability - to instantly recall the three reliability aspects whenever this topic appears on an exam.
