Wireless Sensor Network (WSN) is a collection of wireless nodes forming a network without any fixed infrastructure or centralized authority. In WSN, the sensors are free to organize themselves into a network without requiring any fixed infrastructure like base stations. It is an attractive networking option for connecting large number of sensors spontaneously.. Security in WSN is essential even for basic network functions like routing which are carried out by the sensors themselves rather than specialized routers or nearby sinks. The intruder sensor or Sink in WSN can come from anywhere with more resources availability, along any direction, and target any communication channel in the network. Intrusion prevention techniques such as authentication and encryption are applicable in the wired and infrastructure based cellular network. In the case of infrastructure-free WSN, these techniques are not applicable. The dynamic nature of the WSN also means that trust between nodes in the network is essentially non-existent. Without trust, preventive measures are unproductive and measures that are strictly on a certain level of trust between nodes are susceptible to attacks themselves. There is a need for intrusion detection and response to provide a second line of defense. Intrusion detection is the process of detecting and responding to malicious activity that is aimed at attacking the network. In this paper we have explored general security threats in wireless sensor network and analyze possible security threats |
