The severe constraints and demanding deployment environments of wireless sensor networks make security for these systems more challenging than for conventional networks. However, several properties of sensor networks may help to solve the challenge of building secure networks. The unique aspects of sensor networks may allow the defenses not available in conventional networks. In this paper, the security related issues and challenges in wireless sensor networks have been investigated. The security threats are identified and some of the proposed security mechanisms for wireless sensor networks have been reviewed.
