Wireless sensor networks have sensor nodes which can process the input data from attached sensor s. The results are transmitted wirelessly to the transit network. Large number of applications is widely benefited from such networks making it vulnerable to threats. It is becoming a growing area for research and development as wireless sensor networks are used in military, surveillance, etc. Security for WSNs is very important as the nodes are not physically protected. In this paper, the authors analyses the various security threats available for WSNs. In this paper, a novel technique for providing faced by WSNs.
