IPSEC is a near-ubiquitous VPN security standard, designed for use with TCP/IP networks. It works at the
packet level, and authenticates and encrypts all packets traveling over the VPN Tunnel.
IPSEC VPNs exchange information through logical connections called SAs(Security Associations). An SA is
simply a definition of the protocols, algorithms and keys used between the two VPN devices (endpoints).
