ITPEC IP October 2024 Question 41
ITPEC IP October 2024 — Question 41 of 100
The incident damages integrity and availability, but it does not state that confidentiality was lost. Files were deleted and some could not be recovered, so the completeness and correctness of the stored information were impaired: integrity was lost. Work could not be performed for several hours, so authorized users could not access the required service: availability was also lost. The files had been encrypted, and no disclosure to an unauthorized party is described.
Answer (c)
Why not others:
- (a) confidentiality concerns unauthorized disclosure, which the incident does not report
- (b) includes confidentiality but omits the clearly affected availability
- (d) includes availability but omits the loss of integrity caused by deletion
Key rule: CIA means confidentiality against disclosure, integrity against unauthorized loss or alteration, and availability for timely authorized use.
