The inbuilt flexibility along with easy set-up and low maintenance cost causes MANETs to be increasingly useful in catastrophe management, battlefield surveillance; etc. The infrastructure-less performance of MANET has made it more vulnerable to intrusion than ever before making the security of network all the more acute. As the previously used security systems fail to protect the MANET from insider attacks, the need for an Intrusion Detection System (IDS) becomes evident. IDS based on Mobile Agents is long been used for se-curing the MANET. The prior works seem to suffer from computational overhead leading to performance. This paper proposes a mobile agent based IDS in order to reduce the overheads.
