Sensor networks are expected to play an essential role in the upcoming age of pervasive computing. Due to their constraints in computation, memory, and power resources, their susceptibility to physical capture, and use of wireless communications, security is a challenge in these networks. In this paper we just take a glance at the wireless technology and take a tour of wireless sensor networks. This paper gives brief outline related to wireless sensor network and its applications in various fields. Also we have given the software and hardware platforms for wireless sensor network. Also we mentioned the possible attacks on the WSN and their countermeasures. Finally we have pointed out that for designing a sensor network one must build a mechanism which is secure from external attackers.
