The Design And Implement Of Network Probe System For Internet Information Center

Probe and audit of Internet is a new method of network security after the firewall and the Intrusion Detection Systems.Traditonal products of network security are uneasy to provent the information from leaking and get the evidence of leaking.Many deparments of government which are sensitive about the Internet information are eager to probe and audit the Internet information.It's a problem which need the whole network security industry to solve that how to gather and manage the Internet information standardly.Network monitoring is to gather and supervise the information on the internet in time,and find out that which internet message is harmful and suspicious, then we can adopt relevant step such as recording and alarming,and analyzing the message.The thesis has researched the security auditing technology about how to watch the whole Internet and record the harmful action.It has designed and implemented the requirement of the Internet probe system, so that the government could improve the defending ability on Internet, proventing the basic facilities from destroying,and maintain the security of the computer information system in the important departments of the government and the enterprises.At first the thesis analyses the background and the necessity of the appearance of Internet monitor.Then it researchs the relevant technology about the Internet probe system design. It expounds the advantage of using Linux as the design platform.It analyses the TCP/IP system structure in detail and estimates the necessity of using POSIX multiple-Threads technology.It uses the XML format as the format for data exchange.The thesis analyses the business work flow of the...
