Wireless Sensor Network is one of the most prominent technologies that have wide range of applications. Even though WSN has a lot of innovative features it has a huge concern towards security. This might be mainly due to the absence of a physical line of defence between the sensor nodes. But there are also other issues mounting the security concerns in a WSN. In order to make a WSN secure and confidential there should be 100% defence against any kind of intrusions in the network before it can harm any node. Therefore Intrusion Detection Techniques have their own vital importance in the area of WSN.
