ITPEC FE Subject A April 2026 Question 29
ITPEC FE Subject A April 2026 — Question 29 of 60
Integrity — ISO/IEC 27000 defines it as the property of accuracy and completeness.
The standard's three core properties are:
- •Confidentiality — information is not made available to unauthorized parties
- •Integrity — information is accurate and complete
- •Availability — information is accessible when an authorized entity needs it
Answer (d)
Why not others:
- (b) Availability — about being reachable on demand, not about the data being correct
- (c) Confidentiality — about who may see the data, not about its correctness
- (a) Authentication — a mechanism for verifying an identity, not one of the three properties of an information asset
Key rule: The wording in the question maps directly onto the definitions: "accuracy and completeness" is integrity, "accessible when required" is availability, "not disclosed" is confidentiality.
