Abstract:
Wireless sensor networks (WSNs) are vulnerable to adversaries as they are frequently deployed in open and unattended environments. Adversaries can extract vital information, such as security keys, from compromised nodes and use them to launch insider attacks, so detecting when a node is compromised is important to securing WSNs. In this paper, we present ComSen, an accurate and lightweight intrusion detection system for identifying compromised nodes in wireless sensor networks. Through quantitative results, we demonstrate the benefits of ComSen: (1) it is not vulnerable to slander attacks, (2) it provides detection rates of 99% and false positive ratios of less than 2% in environments with loss rates of 30%, which cannot be achieved by existing systems, (3) it runs on most WSNs because it uses common application features (sensor readings, receive power, send rate, and receive rate) and can adjust its detection behavior if the sensor application doesn't have periodic transmissions or lacks inter-node communication, and (4) it has low memory, computation, and communication overheads that allows it to scale to networks of over thousands of nodes.
