The wireless sensor network is an emerging technology in the field of communication. This technology has many advantages but the security issues have been not given much consideration till now. Due to this neglecting, few loopholes in the security have started to occur such as wormhole attack, blackhole attack, etc. In this paper, the various aspects have been covered regarding security provisioning in wireless sensor networks. Also some light has been thrown on the various types of attacks and its classification. The special attention has been paid to wormhole attack with the support of some already published works.
