ITPEC IP April 2022 Question 37
ITPEC IP April 2022 — Question 37 of 100
CDs and DVDs containing confidential information should be physically destroyed before disposal. Breaking or shredding the recording layer makes the stored data impractical to read or recover. Disposal controls must target the medium that actually holds the information.
Answer (a)
Why not others:
- (b) destroying a CPU does not erase information stored on the PC's drive
- (c) ordinary file deletion from USB memory usually removes references but may leave recoverable data
- (d) an envelope placed with general trash can be opened, so confidential paper should be securely shredded, pulped, or incinerated
Key rule: Before disposal, make confidential data unrecoverable by secure erasure or destruction of the actual storage medium.
