Security issues in wireless sensor networks plays key role. The authors have to provide adequate security for wireless sensor networks. This work deals with some security issues over Wireless Sensor Networks (WSNs). A survey of recent trends in general security requirements, typical security treats, intrusion detection system, key distribution schemes and target localization is presented. In order to facilitate applications that require packet delivery from one or more senders to multiple receivers, provisioning security in group communications is pointed out as a critical and challenging goal.
