Abstract


With the fast advance of computer network technology, network security is increasingly more important. The rapid development of network security is bringing about changes day after day. For example: preventing virus software、 passive firewall and intrusion detection system of initiative, and so on. As a kind of active measure of information assurance, IDS(Intrusion Detection System) can find the intrusion from the trace and pattern of their actions. It has been another line of defence behind firewall. It acts as the effective complement to traditional protection techniques. However, the traditional intrusion detection systems have some shortcomings in certain aspects, such as flexibility, interoperability etc Therefore, people begin to seek for new technologies. To solve these problems, we introduce mobile agent technology in intrusion detection system. It has many advantages for the high-speed network and different operation system, such as real-time character and flexibility. In this paper, we bring out a distributed intrusion detection systembased on mobile agent------MADIDS, which combines the IDS Snort and mobileagent platform Aglet. In MADIDS, the detection tasks are implemented by two type of detection mobile agents, which make the system have certain flexibility, interoperability and intelligence as well as good performance.Firstly, we analyze and summarize the technologies of IDS and mobile agent. We introduce the Snort in IDS and analyze its source code carefully, also introduce the Aglet in mobile agent and analyze its system frame and object model, of course, we narrate the process of setting up a platform of Aglet.After providing the background knowledge of intrusion detection system and mobile agent, we introduce the design of the system architecture and expound the design and implementation of MADIDS in detail. This system is composed of three modules: control server、 intrusion detection module and intrusion response module. The GUI of control server either can be created or can be replaced by Tahiti, the graphics user interface of Aglet. The intrusion detection module also can be replaced by Snort. The module of intrusion response is implemented by a mobile agent process which work on the platform of Aglet and feedback the alert information logged by Snort to control server.At the end of this paper, we summarize the advantage and disadvantages of this system, and discuss the future research directions of MADIDS.
