It is major security management means to combine protocol data analysis with audit and monitoring. So we develop the monitor system for information security. It adopts advanced technology of state check, analyses the emails and files passing in and out real-time, audits the communicated content according to requirement, controls the network connects.The scheme and leading technology or method of this software are detailed in the dissertation, so does module partitions and interfaces, functions and running way.The production can availably protect Intranet against letting out secrets, intruded and attacked from Internet. It offers tool to manage information system in security and constitute security strategies. It is a safeguard for information system of government, companies and enterprises.
