Explanation

IPSec provides two main security protocols: AH (Authentication Header) and ESP (Encapsulating Security Payload). AH provides only authentication and integrity - it does NOT encrypt the payload, so it offers no confidentiality. ESP provides encryption (confidentiality), authentication, and integrity. MD5 is a hashing algorithm used for integrity checking, not an IPSec protocol. PSK (Pre-Shared Key) is an authentication method, not a security protocol. When confidentiality (encryption) is required, ESP must be used.
