Wireless sensor networks are increasingly used in a wide range of potential applications, including security and surveillance, control, actuation and maintenance of complex systems and fine-grain monitoring of indoor and outdoor environments. The nature of wireless sensor networks makes them very vulnerable to attack. The mobile nodes are randomly distributed, there are no physical obstacles for the adversary, therefore, they can be easily captured and attacks can come from all directions and target any node. Consequently, security of Wireless Sensor Networks (WSN) is the most challenging for this type of network. Intrusion Detection Systems (IDSs) can play an important role in detecting and preventing security attacks.
