Executive Summary

The Internet has instantly evolved into a vast global network in the growing technology. TCP/IP Protocol Suite is the basic requirement for today's Internet. Internet usage continues to increase exponentially. So network security becomes a growing problem. Even though IPv6 comes with build mechanism IPsec for security, it lacks security in Application layer of TCP/IP protocol suite. IPv6 solves most of the security breaches for IPv4 with the use of IPsec. But IPsec doesn't have any security provision in the application layer. So there is a need for security mechanism. In this paper some of the security flaws of IPv6 are identified and the authors present a new architecture for TCP/IP protocol suite.
