Abstract- The successful deployment of vehicular ad hoc networks (VANETs) has to overcome the serious security threats which impair the operation of different vehicular applications. This paper presents the vulnerabilities of vehicular ad hoc networks and analyzes some of the security problems inherent in VANETs and also presents proposed solutions to overcome some of the vulnerabilities and security problems.
