This paper presents a study of the different vulnerabilities, threats and attacks for Wireless Sensor Networks. Effective management of the threats associated with wireless technology requires a sound and thorough assessment of risk given the environment and development of a plan to mitigate identified threats. An analysis to help network managers understand and assess the various threats associated with the use of wireless technology and a number of available solutions for countering those threats are discussed. WSNs consist of multifunction and spatially distributed sensor nodes that are small in size and communicate wirelessly over short distances.
