Wireless sensor network is one of t

Wireless sensor network is one of the most growing technology for sensing and performing the
different tasks. Such networks are beneficial in many fields, such as emergencies, health monitoring,
environmental control, military, industries and these networks prone to malicious users' and physical attacks
due to radio range of network, un-trusted transmission, unattended nature and get access easily. Security is
a fundamental requirement for these networks. In this paper, our center of attention is on physical attacks and
issues in wireless sensor networks. Through this review, easily identify the purpose and capabilities of the
attackers. Further, we discuss well-known approaches of security detection against physical attacks

Provision of security in network is a vital requirement
for sufficient and stable network in communication
technologies. It is a complex feature to deploy in wireless
sensor network because due to the nature of network.
The most physical security attacks disturb the WSN
security dimensions like confidentiality, integrity,
authenticity and availability. In this short review
the security issues and physical attacks analyzed. We try
to focus more specific knowledge for researchers.
The approach is to classify and compare the WSN’s
physical attacks, their properties such as their strategies
and effects and finally their associated detection and
defensive techniques against these attacks to handle
them independently and comprehensively
