IPSec architecture

Question description

In this assignment, you will research and learn about the Internet protocol security (IPSec). You will then use what you have learned to answer some specific questions about the application of this architecture. Research the following using the library and/or the Internet.

• IPSec architecture
• Authentication header (AH) protocol
• Encapsulating security payload (ESP) protocol

Provide a 1-2-page paper that responds to the following questions.

• The IPSec architecture document states that when 2 transport mode security associations (SAs) are bundled to allow both AH and ESP protocols on the same end-to-end flow, only 1 ordering of security protocols seems appropriate: performing the ESP protocols before performing the AH protocol. Why is this approach recommended rather than authentication before encryption?
• In the secure sockets layer (SSL) and transport layer security (TLS), why is there a separate change cipher spec protocol rather than including a change_cipher_spec message in the handshake protocol?

Be sure to document your references using APA format.
