Research on Distributed Intrusion Detection System

Intrusion detection has emerged as an important approach to security problems. The common problems of current intrusion detection systems are analyzed in this paper. Based on these, a distributed IDS framework model based on independent agents is proposed. This paper describes the function of entities in detail. The proposed model is an open system with good scalability. Agents are independent individually, while they can communicate and cooperate one another to take actions. Then the key modules are implemented in mobile agent platform-IBM Aglets and the results of experiments are discussed and analyzed quantitatively. Finally, implementation issues and future work are presented

1. Introduction

Along with the increasing wide applications of computer and network technologies, the security problems of information system are becoming more complicated. In order to guarantee the resources of system, the concept of intrusion detection is proposed.
