MANET is an association of large no. of sensor nodes and having self-directed commands using the unprotected wireless connection. The individual needs in the network can accompany and leave the network without any permission. MANET is an infrastructure less network. The network topology is rapidly changed due to nodes mobility, resource constraints and bandwidth limitation of wireless medias. This nature of nodes leads to different type of security threats. MANET suffers from disruption so that nodes are not able to take part in path finding method with a target to spoil full network functioning. A no. of protocols has been found for efficient routing. There are many types of securities attack which disturb the network operation. In this paper, we focus on many proposed routing protocol for MANET, types of security attacks and a survey on existing techniques of detection and prevention of attacks is presented
