In the CIA triad used to describe the objectives of cyber security, what does the 'Integrity' element primarily protect against?
Integrity protects against unauthorised or accidental alteration of data. It ensures information remains accurate, complete and trustworthy. Disclosure to outsiders concerns confidentiality, while loss of access to systems concerns availability, so those options describe the other two parts of the CIA triad.
- AUnauthorised disclosure of information to outsiders
- BUnauthorised or accidental alteration of dataCorrect
- CLoss of access to systems during an outage
- DDenial of ownership of a transaction by its sender
Explanation
Integrity means data stays accurate and complete and is changed only by authorised parties. Disclosure is a confidentiality concern, and system outages are an availability concern. Denial of a transaction by its sender is non-repudiation, not integrity.
Did you get it right without looking?
One question tells you little. A timed set on Cyber Security shows your real accuracy, how long you take and where you lose marks.
