TCP Split Handshake: The (Never)ending Story… – …
Transmission Control Protocol - Wikipedia TCP protocol operations may be divided into three phases. Connections must be properly established in a multi-step handshake process (connection establishment) before entering the data transfer phase.After data transmission is completed, the connection termination closes established virtual circuits and releases all allocated resources.. A TCP … Debugging Everything – Code and other everyday things The TCP Split Handshake attack is initiated by server, which sends to the client non-transitionally configured handshaking packets. There is lot of rumor about a TCP split-handshake vulnerability that can affect firewalls and other networking and security devices.

Transmission Control Protocol - Wikipedia
It is described in the RFC 793 (TCP) section 3.4. But I doubt you will ever see such a handshake, because it does not fit into the typical client-server-scenario where one end is waiting for connects and the other end does the connect. Edit: the handshake you envision exists and it is called "split handshake". Transmission Control Protocol - Wikipedia TCP protocol operations may be divided into three phases.
