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. This article proposes a detailed survey of various Intrusion Detection Techniques with a comparative study highlighting the advantages and disadvantages of various schemes.
