Security is one of the major qualitative parameter suggested by IETF MANET group for Mobile ad-hoc network (MANET)-which is an infrastructure less network with randomly moving nodes changing their network topology. This is the network where a node is itself responsible for creating, maintaining and terminating a route depending on the routing protocol. The absence of a central infrastructure makes MANET vulnerable to various security threats. These attacks are exploiting data, routing protocols and layers of the networks. A lot of research has already been done in the past but none of them could bring a secure approach in the MANET. This paper is representing a part of an ongoing research. In this paper we are presenting various attacks in an organized way according to the layers of internet model and presenting an overview regarding all the threats and attacks possible on MANETs.
