Security Flaw in TCP/IP and Proposed Measures

The whole Internet is based on TCP/IP protocol suite. The inherent flaw in the TCP/IP makes a cascading effect for other attacks like flooding, fingerprinting, and many more. All the switching and routing mechanisms are based on the TCP/IP, so it is safe to say that TCP/IP is the backbone protocol suite for communication for all major Internet applications. The architectural flaw of TCP/IP protocol and possible ways to mitigate those flaws are discussed in this paper. Especially, the problem with connection phase in TCP and how SYN/ACK/RST packets can be used to breach an ongoing handshake are brought in light. In order to help create a safe information network environment in the future, this study aims to provide some references.
