Because IPSec is integrated at the Internet layer (layer 3), it provides security for almost all protocols in the TCP/IP suite, and because IPSec is applied transparently to applications, there is no need to configure separate security for each application that uses TCP/IP.
IPSec does not work on an OSI layer. It is part of the TCP/IP model. When used as a tunneling layer, it is effectively layer 2.5. When just used as an annotation, itâs an IP option and thus part of the network layer. Views Â· View Upvotes.
