Multi-protocol information resolving system based on network packet

Abstract

The invention discloses a multi-protocol information resolving system based on a network packet, comprising gateway equipment 1, a client computer 2, a server 3, a database 4 and an information security server 5, wherein the server 3 is respectively connected with the gateway equipment 1, the client computer 2, the database 4 and the information security server 5; the difference is that the server 3 is provided with a network packet capturing module 31, a protocol analysis module 32, a packet recombination module 33, a mail information reduction module 34, an MSN instant messaging information reduction module 35 and a webpage information reduction module 36. The method reduces to obtain all content of the E-mail, MSN instant communication and HTTP requested key information by the protocol analysis, packet recombination and application layer resolution to the original packet, and two filtering modes of pre-filtering and back filtering are adopted to accurately judge and analyze content filtering.

Description

Technical field [0001] The invention relates to a management device for real-time analysis of network behaviors, in particular to a system for analyzing multi-protocol information based on network data packets. Background technique [0002] With the rapid development of information technology, especially the widespread application of computer networks, the globalization of information has been promoted. Various government departments, enterprises and institutions use the Internet to conduct various operations such as information inquiry, mail sending and receiving, and online communication.
