Which security protocols are standard IPsec components?

• A. IPsec commonly uses TCP and UDP for transport.
• B. TLS and DTLS are IPsec protocols.
• C. ESP and AH are standard IPsec security protocols.
• D. SSH and SSL are IPsec protocols.

Answer: (C)

IPsec standard components are ESP (Encapsulating Security Payload) and AH (Authentication Header). ESP provides confidentiality by encrypting the payload and also offers integrity and authentication for that data, with optional protection for the IP header in some configurations. AH, on the other hand, provides data integrity and authenticates the entire IP packet, but it does not provide encryption. This combination is what defines IPsec’s security capabilities at the network layer. TLS/DTLS, SSH, and SSL are separate security protocols used at different layers or for different purposes, not part of IPsec. TCP/UDP are transport-layer protocols, not IPsec security protocols.
