Wireless Sensor Network Security Attacks: A Survey
Abstract
Wireless Sensor Networks (WSNs) are a rapidly growing area for research and commercial development. Originally used in military applications, their commercialization offers potential low cost solutions for real-world monitoring and process control. Since they may be deployed in hostile, unattended, environments and may collect sensitive data, they may be prone to attack by entities that wish to interfere with their operation and/or usurp or alter the information they collect. While their low cost enhances their desirability as a monitoring solution, it also presents inherent resource and computing constraints. These constraints are major obstacles for the implementation of traditional security paradigms. Consequently, one of the most active areas of research in Wireless Sensor Networks is security. This chapter takes a representative survey of the types of security attacks WSNs may be subjected to. Additionally, steps that may be taken to mitigate these attacks are also discussed. Intrusion Detection Systems, a paradigm for monitoring network activities for malicious behavior, are introduced, and specific examples of them are discussed.
