TCP - IP White Papers

Securing Virtual Private Networks

Tags:
tcp - ip

Overview A publicly shared network such as the Inter net suffers two key disadvantages. The first is that the universally accessible nature of the Internet makes eavesdropping, packet manipulation, and the forging of identities (spoofing) a major concern. Virtual Private Networks (VPNs) currently provide protection from each of these threats through encryption, data-integrity checking, and authentication. This paper discusses the current state of some common VPN standards. VPN standards address data encapsulation at the source, tunneling of data through various media and protocols, and un-encapsulation at the destination. Encryption, error checking, and authentication at the end points are also addressed by these standards.
