| Abstract: | A content security oriented monitor system used in LAN（local area network） is designed and implemented. It contains two modules, one is the recovery of network data, while another is the data analysis and filter. The system captures data packets with aside-way monitor mode, then it realizes the application data recovery by protocol analysis and session recovery technology, finally it does the security inspection on recovered application data by text analysis and filter technology. This system could do real-time monitor on the network information, so it efficiently implemented the inspection on information in LAN. |
