14.1 Overview

A virtual private network (VPN) provides secure communications between sites
without the expense of leased site-to-site lines. A secure VPN is a combination of
tunneling, encryption, authentication, access control and auditing. It is used to
transport traffic over the Internet or any insecure network that uses TCP/IP for
communication.
Internet Protocol Security (IPSec) is a standards-based VPN that offers flexible
solutions for secure data communications across a public network like the
Internet. IPSec is built around a number of standardized cryptographic techniques
to provide confidentiality, data integrity and authentication at the IP layer. The
following figure is an example of an IPSec VPN tunnel.
