Authentication Headers (AH) and Encapsulating Security Payload (ESP) protocols are the driving force of
IPSec. Authentication Headers (AH) provides the following service except:
A.
Authentication
B.
Integrity
C.
Replay resistance and non-repudiations
D.
Confidentiality
Explanation:
Integrity and authentication for IP datagrams are provided by AH, but AH does not provide Confidentiality.
Incorrect Answers:
A: Authentication is provided by AH.
B: Integrity is provided by AH.
C: Authentication Headers (AH) might also provide non-repudiation, depending on which cryptographic
algorithm is used and how keying is performed. With non-repudiations comes replay resistance.Harris, Shon, All In One CISSP Exam Guide, 6th Edition, McGraw-Hill, New York, 2013, p. 862
