Preliminaries of Orthogonal Layered Defence Using Functional and Assurance Controls in Industrial Control Systems

“…The key elements to be considered is the method selected to carry out risk assessments, deployed risk models, and adaptation of risk appetite to properly enumerate the threat landscape in particular cases in which IT and ICS integration takes place. Risk-mitigation plans have recently found their way in the cyber-physical ICS environment [51][52][53]. The key components of an informed defence-in-depth framework, within which assurance and functional controls could be integrated, are presented as follows.…”

Watch Me, but Don't Touch Me! Contactless Control Flow Monitoring via Electromagnetic Emanations

“…Offline formal control logic analysis have been investigated by solutions such as TSV [34], through symbolic execution and model checking mechanisms. Solutions such as WeaselBoard [38] and CPAC [10] perform runtime PLC execution monitoring using control logic and firmware-level reference monitor implementations. Most related to our paper, there have been attack and defense solutions that employ side-channel analyses to either disclose secret information (e.g., cryptographic keys [17]), or detect anomalous misbehavior (e.g., execution tracking [31]).…”

“…The increased complexity may trigger human mistakes and operational errors allowing an attack or an intrusion. Considering these issues, Etigowni et al [139] propose the cyber-physical access control solution (CRAC). The authors focus on a smart grid that comprises of sensors and programmable logic controllers (PLCs).…”
