ITPEC IP October 2018 Question 35
ITPEC IP October 2018 — Question 35 of 100
Confidential CDs and DVDs should be physically destroyed before disposal. Shredding or otherwise rendering the recording layer unreadable prevents later recovery of the stored information from discarded optical media.
Answer (a)
Why not others:
- destroying a PC's CPU leaves its storage device and data intact
- ordinary file deletion on USB memory may leave recoverable data
- placing documents in an envelope with general trash does not prevent retrieval
Key rule: Sanitize or physically destroy the component that actually stores the confidential data, and use a controlled disposal process.
