Abstract: The Internet of Things (IoT) relies heavily on wireless communication enabled devices that are able to discover and interact with other wireless devices in their vicinity. The communication flexibility coupled with software vulnerabilities in devices, due to low cost and short time-to-market, exposes them to a high risk of malware infiltration. An attacker might stealthily gain control over a large number of network devices using device-to-device (D2D) communication in order to launch a coordinated cyber-physical attack resulting in disruption of the critical infrastructure facilities, or for malicious purposes such as collecting ransom.
In this talk, I will describe an analytical model to study the D2D propagation of malware in wireless IoT networks. Leveraging tools from dynamic population processes and point process theory, I capture malware infiltration and coordination process over a network topology. The analysis of mean-field equilibrium in the population is used to construct and solve an optimization problem for the network defender to prevent botnet formation by patching devices while causing minimum overhead to network operation. The proposed methodology may serve as a basis for assisting the planning, design, and defense of such networks from a defender’s standpoint.
