Ad hoc networks are highly dynamic and the individual nodes forward traffic on behalf of other nodes. These networks enjoy increasing interest, to a great extent because they have useful applications in a wide range of situations, including search and rescue operations (e.g., connecting rescue workers at a location with limited availability of cell phone infrastructure), personal area networking (e.g., allowing wireless users to use equipment, such as printers, in public places), as well as military operations. While ad hoc networks allow for advanced functionality over traditional networks, they at the same time exhibit numerous challenges including the limited wireless transmission range, the broadcast nature of the wireless medium, mobility induced routing changes and battery constraints of the individual nodes. Perhaps the greatest challenge of all is securing these networks. This has recently spurred a tremendous amount of research activity. In this symposium we discuss various attacks on wireless ad hoc networks. One such attack is the so-called stealth attack. This is an attack that can be performed with low effort and cost, and very low risk of detection of the identity (or whereabouts) of the perpetrator. This type of attack is particularly dangerous, since a small number of malicious parties can disconnect a large network with small effort and minimal risk of tracing. We propose methods to address stealth attacks and other attacks.
