The term Internet of Things (IoT) has come to denote the wide-spread deployment of sensors and actuators with ubiquitous inter-connectivity, potentially to the Internet, to monitor physical systems and critical infrastructure such as electrical utilities, transportation systems, SCADA systems, factories and buildings.
The security of such systems has unfortunately not attracted as much attention as it deserves. The spate of recent attacks that have been realized on these embedded sensors bears testimony to their ubiquity, but also raises serious concerns about their security. These devices, by virtue of their deployment, can be used to cripple critical infrastructure that was once considered invulnerable.
Our research addresses a number of aspects of IoT security such as the passive data collection and the reconstruction of SCADA protocols in order to allow the cognitive detection of security relevant events.
