Vehicular Ad-hoc NETworks (VANETs) are the most prominent enabling network technology for Intelligent Transportation Systems (ITS). VANETs provides many new exciting applications and opportunities albeit transportation safety and facilitation applications are their core drivers. Security of vehicular networks remains the most significant concern in VANETs deployment - because it is mandatory to assure public and transportation safety. In this paper, the authors review the various dimensions of VANETs security including security threats, challenges in providing security in vehicular networks environment, requirements and attributes of security solutions.
