Vehicular ad-hoc networks (VANETs) have become the focus of much discussion due to its potential role in helping to improve traffic management and safety and enable a wide range of value-added services such as collision warning/avoidance and work zone warning. Because information transmitted over a vehicular network is sensitive and can affect important safety decisions, security requirements for VANETs applications prove stringent. Thus, fail-safe security is mandatory. However, providing security in vehicular networks raises important privacy concerns also worth considering. Security and privacy are the two main concerns motivating robust vehicular network designs. In this paper, we will discuss some threats and attacks that can be exploited, and in response, present some viable security solutions.
