ABSTRACT:
A one-way proxy system is provided that supports one-way analysis of a transport control protocol (TCP) data stream. The one-way proxy system is used to intercept a TCP data link between two respective TCP endpoints. A one-way analyzer such as a one-way content filter, virus scanner, or firewall may be used to analyze a TCP data stream that is intercepted by the one-way proxy system. The one way proxy system preserves TCP options and TCP properties associated with the TCP packets in the TCP data stream, so that an existing TCP session between the TCP endpoints can survive in the event of a hardware bypass operation. The one-way proxy has a low overhead because significant TCP processing of the TCP data stream is only required in one direction.
