The significant advances of hardware manufacturing technology and the development of efficient software algorithms make technically and economically feasible a network composed of numerous, small, low-cost sensors using wireless communications, that is, a wireless sensor network. Sensor networks have great potential to be employed in mission critical situations like battlefields but also in more everyday security and commercial applications such as building and traffic surveillance, habitat monitoring and smart homes etc. However, wireless sensor networks pose unique security challenges. Security is becoming a major concern for WSN protocol designers because of the wide security-critical applications of WSNs .In this paper we have made an effort to document all the known security issues in wireless sensor networks and discusses a wide variety of attacks in WSN and their classification mechanisms and different securities available to handle them including the challenges faced. In this paper we took up the challenge and have proposed an integrated comprehensive security that will provide security services for all services of sensor network. The sensing technology combined with processing power and wireless communication makes it profitable for being exploited in great quantity in future. The wireless communication technology also acquires various types of security threats.
