Abstract: A secure network communication system and method for secure data exchange using TCP are disclosed. The system provides data exchange between a client and server, through an agent and broker interconnected to exchange data over an unsecured network. Upon receipt of a control packet from the client, the broker forwards a modified control packet to the agent using a secure protocol. The agent inspects the modified control packet and forwards it to the server. Upon receipt of a response packet from the server, the agent forwards the response packet to the broker using a secure protocol. Upon receipt of the response packet, the agent modifies the response packet and forwards it to the client. If the exchange of control packets indicates establishment of a TCP session, the agent and the broker establish a data channel between themselves to create a transparent TCP channel between the client and the server.
