The IPSec model is an architecture composed of standard rules for protecting IP traffic. IPSec is also a set of protocols utilized to secure IP packet exchanges that operate at the Internet Layer of the TCP/IP reference model. IPSec utilizes certificates and Public Keys to authenticate and validate the sender and receiver.
Tunnel and Transport are the two telecommunication modes supported by IPSec. IPSec standard rules can be incorporated into transport and tunnel mode encapsulation. As a distinctive feature, Tunnel mode provides two additional header records for sending messages, thus requiring more processing. In addition, Tunnel mode is usually implemented between two gateways or a gateway and server.
