“Wireless Sensor Networks (WSNs) are currently using in various application areas like as military, health care, ecological, medical, process management, environmental, industrial, agriculture etc. In this article we discussed about the security issues in WSNs. First of all we constraints on the obstacles in WSNs, requirement for security and different attacks at various levels with their solutions in WSNs. Wireless sensor network is one of the most growing technology for sensing and performing the different tasks. Such networks are beneficial in many fields, such as emergencies, health monitoring, environmental control, military, industries and these networks prone to malicious users' and physical attacks due to radio range of network, un-trusted transmission, unattended nature and get access easily. Security is a fundamental requirement for these networks. In this paper, our center of attention is on physical attacks and issues in wireless sensor networks. Through this review, easily identify the purpose and capabilities of the attackers. Further, we discuss well-known approaches of security detection.
