A system dynamics approach for assessing the impact of cyber attacks on critical infrastructures
The massive proliferation of information and communications technologies (hardware and software) into the heart of modern critical infrastructures has given birth to a unique technological ecosystem. Despite the many advantages brought about by modern ...
Multilayer hybrid modeling framework for the performance assessment of interdependent critical infrastructures
The heterogeneity and tight coupling of modern critical infrastructures make it challenging to create tractable descriptions of their emergent behaviors. Classic analytical methods do not provide adequate insights into system behavior and do not fully ...
Risk mitigation strategies for critical infrastructures based on graph centrality analysis
Dependency risk graphs have been proposed as a tool for analyzing cascading failures due to critical infrastructure dependency chains. However, dependency chain analysis is not by itself adequate to develop an efficient risk mitigation strategy - one ...
Constructing cost-effective and targetable industrial control system honeypots for production networks
Critical infrastructure assets - and especially industrial control systems - are at risk. Malicious actors are constantly developing exploits that sneak past security controls. Honeypots offer an opportunity to acquire knowledge about the tactics, ...
Control variable classification, modeling and anomaly detection in Modbus/TCP SCADA systems
This paper describes a novel domain-aware anomaly detection system that detects irregular changes in Modbus/TCP SCADA control register values. The research discovered the presence of three classes of registers: (i) sensor registers; (ii) counter ...
