A vehicular ad-hoc network (VANET), is an instance of intelligent transportation system that provides vehicle-to-vehicle communication aided by road side infrastructure for in-vehicle entertainment and safer road environment. VANET is characterized by highly mobile vehicles, predetermined topology and the requirement of reliable time bound message delivery over error prone shared wireless medium. The security solutions are constrained by these characteristics. In this paper we are discussing the various type of attack on VANET along with intersection attack on anonymity and the security issue that need to kept in mind while developing any protocol to make VANET secure. Simulation and results indicate that intersection attack is breach the privacy even though cryptographic and noncryptographic security mechanism is enabled over the VANET.
