Abstract: With the advancement in radio technologies like Bluetooth, IEEE 802.11, a new concept of networking has emerged; this is known as ad hoc networking where potential mobile users arrive within the range for communication. As network is becoming an increasingly important technology for both military and commercial distributed and group based applications, security is an essential requirement in mobile ad hoc network (MANETs). Compared to wired networks, MANETs are more vulnerable to security attacks due to the lack of a trusted centralized authority and limited resources. Attacks on ad hoc networks can be classified as passive and active attacks or internal attack and external attacks, the security services such as confidentiality, authenticity and data integrity are also necessary for both wired and wireless networks to protect basic applications. One main challenge in design of these networks is their vulnerability to security attacks. In this paper, we study the threats an ad hoc network faces and the security goals to be achieved.
