Wireless Sensor networks are vulnerable to security attacks due to the broadcast nature of the transmission medium
Wireless sensor networks have an additional vulnerability because nodes are often placed in a hostile or dangerous environment where they are not physically protected.
Basically attacks in WSN are classified as
active attacks
passive attacks
Monitor and Eavesdropping: this is the most common attack to privacy. By snooping to the data, the adversary could easily discover the communication contents
Traffic Analysis: Even when the messages transferred are encrypted, it still leaves a high possibility analysis of the communication patterns.
Camouflage Adversaries: One can insert their node or compromise the nodes to hide in the sensor network. After that these nodes can copy as a normal node to attract the packets, then misroute the packets, conducting the privacy analysis.
Active Attacks: The unauthorized attackers monitors, listens to and modifies the data stream in the communication channel are known as active attack. The attacks which act on the network layer are called routing attacks. An unprotected ad hoc routing is vulnerable to these types of attacks, as every node acts as a router, and can therefore directly affect routing information.
Create routing loops.
Extend or shorten service routes.
Generate false error messages.
Increase end-to-end latency.
