ITPEC IP October 2018 Question 38
ITPEC IP October 2018 — Question 38 of 100
Encryption protects communication content from being understood when it is intercepted. An eavesdropper may capture ciphertext, but without the appropriate key should not be able to recover the plaintext, thereby preserving confidentiality.
Answer (c)
Why not others:
- encryption does not prevent a user from accidentally deleting data
- it does not stop manipulation of people through social engineering
- it does not prevent a DoS attack from exhausting server or network capacity
Key rule: Encryption primarily supports confidentiality; backups, awareness controls, and availability defenses address the other threats.
