Analysis of problems associated with IPSec VPN Technology

The original goal of Internet protocol security (IPSec) is to enable the protection of all types of Internet protocol (IP) communications by protecting multiple peers at the network layer, in both the IPv4 and IPv6 environments. IPSec is a standard for securing internet communication and a widely deployed mechanism for implementing virtual private networks (VPNs). Most organisations deploy IPSec VPNs that provide enterprise-level secure remote access by protecting the IP packet exchanged between remote networks or host and an IPSec gateway located at the edge of a private network.. This paper investigates the security issues of IPSec VPN technology with respect to remote access communication.
