ABSTRACT

As the technology of network developing fast, the problem of network security is emerging day by day. In order to temporize this trend, different kinds of network safety methods appear, such as Network Firewall, Virus Detecting, Code Technology, id Authentication ,etc.

Even though, incalculable economic loss are caused because many servers are attacked without effective detecting and defending. Many deficiency in technology are based on this passive defending system, then the active defending system come out of the surface and the representative is Network Inbreak Detecting System.

The Ultimate function of this system is detecting and analysing the net behavior in real time and react to the result of the behavior. By this way, illegal attack can be pre-detected and loss can be avoided. The emphasis of this system is the property of active, not passive. The active property is also the reason while this system is so highly regarded!

This thesis talked about the concept, origin, definition and sort of the Network Inbreak Detecting System. Also common Network Inbreak Detecting System work principle are mentioned. It analyses this system in modular layer, and the stress point is focused on data-package capture, the design and realization of analyse and store modular for network protocol.

Keywords: Intrusion Detection System, data-package, network protocol.
