Wireless Sensor Network (WSN) is regarded as emerging futuristic technology which promises various applications development for people and military. Wireless Sensor Network technology is combined with processing power and wireless communications which makes it vulnerable for security breaches in the future. With the addition of Wireless Technology it is open to all types of security threats. This paper is developed to research on various security issues cum challenges faced by Wireless Sensor Networks. In this paper various security threats are identified and new security mechanisms are proposed for its secure future implementation. A holistic view of security is discussed for providing layered and robust security in Wireless Sensor Networks.
