AI-generated summary of the contribution: This work explores the potential of using electromagnetic (EM) radiation emitted by industrial control systems (ICS) network infrastructure as a window to detect network-based threats and act as a trigger mechanism to activate the forensic readiness features of the ICS infrastructure. The authors propose an approach to monitor ICS network infrastructure using unintentional EM radiation emitted by Ethernet network cables during their regular operation. An empirical evaluation highlights that it is possible to detect various types of denial of service (DoS) attacks through EM emission patterns of Ethernet cables with considerable accuracy. The work introduces an architecture for the ICS infrastructure to be forensic-ready with minimal computational resources while being independent and non-invasive to the infrastructure itself.
