Any node under attack in ad hoc network exhibits an anomalous behavior called the malicious behavior. In this situation, the entire operation of a network gets disturbed and to preclude such malicious behavior several security solutions have been discovered. In this paper, malicious behavior of a node is defined and to defend such behavior, security solutions are presented which are used in furnishing a secure and reliable communication in ad hoc networks.
