Detailed explanation-1: -IPSec. A Layer 3 protocol that defines encryption, authentication, and key management for TCP/IP transmissions. SSL (Secure Sockets Layer) TLS (Transport Layer Security) PPP (Point-to-Point Protocol) SSH (Secure Shell) RDP (Remote Desktop Protocol) VNC (Virtual Network Computing) L2TP (Layer 2 Tunneling Protocol) More items

Detailed explanation-2: -IPSec uses two distinct protocols, Authentication Header (AH) and Encapsulating Security Payload (ESP), which are defined by the IETF. The AH protocol provides a mechanism for authentication only. AH provides data integrity, data origin authentication, and an optional replay protection service.

Detailed explanation-3: -Which two types of encryption protocols can be used to secure the authentication of computers using IPSec? Answers C and D are correct. SHA or MD5 can be used.

Detailed explanation-4: -IPsec protocols IPsec authenticates and encrypts data packets sent over both IPv4-and IPv6-based networks. IPsec protocol headers are found in the IP header of a packet and define how the data in a packet is handled, including its routing and delivery across a network.

Detailed explanation-5: -IPSec is defined by the IPSec working group of the IETF. It provides authentication, integrity, and data privacy between any two IP entities. Management of cryptographic keys and Security Associations can be either manual or dynamic using an IETF-defined key management protocol called Internet Key Exchange (IKE).
