A MANET is a self configuring infrastructure less network of mobile devices which is not connected by wire in which each devices are free to move independently in any direction. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic. The major problem in MANET is security. Since there is no fixed infrastructure there is a possibility for attacking the data. If the users' have the ability to check the attack once comes into the network, they can stop it from doing harm to the system. Intrusion detection techniques can be used to detect or monitor the activity of the system. Recently many data mining techniques are used to solve such problems in network.
