Abstract: Mobile ad hoc network (MANET) is a collection of mobile hosts without the required intervention of any existing infrastructure or centralized access point such as a base station. MANET has the dynamic infrastructure hence it is highly vulnerable to attacks. Several attacks are possible in MANET networks and among them routing attack could cause the worst damage. There are several solutions available for mitigating the routing attacks based on the intrusion response techniques but most of them isolate the malicious node only based on the binary decisions taken for severity in attacks. This will cause additional damage to the network. Risk mitigating techniques is one of the important factor in MANET environment. This paper is about exchange of data between the various nodes in a MANET in a secure manner. we have designed an approach for fusing the evidences so that risk can be assessed effectively and decision of whether an attacker node has to isolated or not. Since always isolation of attacker could result in more serious damages. Therefore our approach isolates only the fake links established by the attacker, unless the attacker is causing more devastating damages.
