The security topic is a conclusive challenge for Wireless Sensor Networks (WSNs) due to the deployment nature and the resources limitations of wireless sensor devices used in such networks. Wireless Sensor Networks are used sometime in very sensitive applications, such as military, airports, and healthcare. Therefore, we must address the security concerns from the beginning of network design. Due to limited resources and computing constraints security in WSNs poses severe challenges as compare to the conventional wireless networks. There are currently massive studies in the field of sensor networks security. So far no comprehensive survey lists the security attacks which consider unique threats to the WSNs with suitable countermeasures against them. In this study we have addressed well known security threats and have provided the reasonable solutions towards effective countermeasures against the threats posed by this hot field of study.

Keywords: Security attacks; Countermeasures; Cross-layer approach; Wireless sensor networks.
