ITPEC IP April 2018 Question 37
ITPEC IP April 2018 — Question 37 of 100
Encryption achieves B by preventing an unauthorized third party from understanding intercepted communication content. Someone may capture encrypted data, but without the decryption key the plaintext should remain confidential.
Answer (d)
Why not others:
- encryption does not recover data that has been altered during transmission
- encryption alone does not identify the person who performed wiretapping
- integrity mechanisms can detect tampering, while investigation and logging may help attribution; these are separate goals
Key rule: Encryption primarily protects confidentiality; integrity checks detect alteration, and authentication or audit evidence supports identity and attribution.
