Wireless sensor networks (WSN) have lot of interest in research due to their wide range of typical application areas such as environmental, military and commercial enterprises. Sensor network possesses unique challenges to protocol builders, because these tiny wireless devices are often deployed in unattended environment with limited capabilities. Hence these networks are vulnerable to different types of malicious attacks. This paper surveyed the different types of attacks and security related issues in WSN. Moreover an analysis about some of the security protocols in two major domains namely, cryptography based protocols and en-route filtering schemes have been done.
