At present, the security issues on MANET have become one of the primary concerns. The MANET is more vulnerable to attacks as compared to wired networks due to distributed nature and lacks of infrastructure. Those vulnerabilities are nature of the MANET structure that cannot be removed easily. As a result, attacks with malicious intent have been and will be devised to exploit those vulnerabilities and to cripple the MANET Operation. Attacks prevention techniques such as a authentication and encryption, can be used as medium of defense for decreasing the possibilities of attacks. These techniques have a limitation on the effects of prevention techniques in practice and they are designed for a set of known attacks.
