Question

Which component is included in IP security?

(a) Authentication Header (AH)

(b) Encapsulating Security Payload (ESP)

(c) Internet key Exchange (IKE)

(d) All of the mentioned

I got this question in semester exam.

The query is from IPSecurity in division Application Layer of Computer Network

Answer 1

The correct choice is (d) All of the mentioned

For explanation I would say: AH ensures that there is no retransmission of data from an unauthorized source, and protects against data tampering. ESP provides with content protection and ensures that there is integrity and confidentiality for the message. IKE is used to make sure that only the intended sender and receiver can access the message.
