Research on Communication Mechanism among Cooperating Multi-Intrusion Detection Agents

In this paper, a communication mechanism of cooperation multi-IDAs(Intrusion Detection Agent) is showed to solve disadvantage of IDS(Intrusion Detection System) with controlling center. After communication mechanism is given among cooperation multi-IDAs, a strategy of loading balance is described. Experiments showed that multi-IDAs can accomplish intrusion detection tasks. After the usage scope of IDS is given and the works next to do are presented, the validity of communication mechanism is confirmed by experiments.

1. Introduction

Both computer system and application software have vulnerabilities and bugs [1], which lead to intrusions frequently. Intrusion detection technique is used to protect a host and network, for fear that they are attacked by hackers. According to data source that used, there are three kinds of intrusion detection techniques [3]: host-based intrusion detection, network-based intrusion detection and hybrid intrusion detection.
