The growing use of internet forces us to work of security aspect also as the security related incident increases. It becomes reason for thinking for organizations to protect their sensitive information with an effective Intrusion detection system (IDS). MAS (Multi-Agent System) are becoming a growing research field which uses agent capability with distributed problem solving approach. Intrusion detection system (IDS) can be treated as a software appliance that monitors network deeds for spiteful actions and generate reports. Here in this paper we are focusing on intrusion detection model based on multi-agent system where the capabilities of autonomous software components can be successfully used to make IDS more efficient, consistent and ingenuousness. Thus the design of distributed network IDS is based on agents which are used as security guard to supervise network and on getting any intrusion it gives alerts and send report also. Multi-agent based IDS has low network traffic load.Keywords- Multi-agent system, intrusion, IDS
