Mobile Ad Hoc NETwork (MANET) is distinguished from other networks mainly by its self configuring and optimizing nature. Being the flexible network, MANET is exposed to various kinds of attacks especially the routing attacks. Attack prevention methods such as intrusion detection system, intrusion prevention, authentication and encryption can be used in defence for reducing certain attack possibilities. Intrusion detection system monitors and analyses the activities of the nodes and determines the performance with the security rules. An intrusion detection system will alert the neighbour nodes if there is any irregularity in the performance of a node. An intrusion response system will take further actions on recovering the affected services and reconfigure the system.
