Mobile ad-hoc networks are highly dynamic, infrastructure lacking and resource constrained networks. These networks consist of set of nodes which are performing the routing functions and simultaneously acting as hosts. The structure of these networks imposes restrictions on monitoring or employing heavy security checks on the activities of the various participants in the network, which is possible with fixed infrastructure networks. Because of these limitations there are possibilities of security breaches in MANET's. The security concerns come from within the network or from outside.
