Sensor networks have been regarded as one of the emerging technologies of the 21 st century and have great future scope. They have been widely used in mission critical applications like military, health as well as civilian applications. The focus of this paper is on a security of sensor networks in various fields. Security is the major concern of a wireless sensor network especially in unattended areas. You will get a general introduction about wireless sensor networks in section I, section II

General Terms Wireless sensor networks, security, security management schemes Keywords Attacks, security, security challenges, security protocols, Wireless Sensor Networks control, surveillance, structural monitoring, medical diagnostics, disaster management, emergency response, ambient air monitoring and gathering sensing information in inhospitable locations [3, 4, 5] .A sensor network is a computer network composed of a large number of sensor nodes. The sensor nodes are densely deployed inside the phenomenon, they deploy random and have cooperative capabilities. Usually these devices are small and inexpensive, so that they can be produced and deployed in large numbers, and so their resources in terms of energy, memory, computational speed and bandwidth are severely constrained. There are different Sensors such as pressure, accelerometer, camera, thermal, microphone, etc. They monitor conditions at different locations, such as temperature, humidity, vehicular movement, lightning condition, pressure, soil makeup, noise levels, the presence or absence of certain kinds of objects, mechanical stress levels on attached objects, the current characteristics such as speed, direction and size of an object. Normally these Sensor nodes consist there components: sensing, processing and communicating.
