Southwest Research Institute (SwRI) in Texas has developed a new intrusion detection system (IDS) to protect military ground vehicles from cyberattacks. Elaborated along with the US Army Ground Vehicle Systems Center (GVSC), this new detection system utilizes different algorithms and digital fingerprints to detect any anomalies in ground communications. These algorithms transmit information through the Controller Area Network (CAN) protocol, which allows the army to identify unknown or invalid nodes connected to the vehicle network. Although IDS technology was thought to be designed for military vehicles, the institute said it could also be integrated into passenger and commercial vehicles.
