Quantifying Security for Networked Control Systems: A Review
Sribalaji C. Anand, Anh Tung Nguyen, André M. H. Teixeira +2
Networked Control Systems (NCSs) are integral in critical infrastructures such as power grids, transportation networks, and production systems. Ensuring the resilient operation of…
Efficiently Computing the Cyclic Output-to-Output Gain
Daniel Arnström, André M. H. Teixeira
The cyclic output-to-output gain is a security metric for control systems. Commonly, it is computed by solving a semi-definite program, which scales badly and inhibits its use for…
Fundamental limitations of sensitivity metrics for anomaly impact analysis in LTI systems
Jingwei Dong, Kangkang Zhang, Anh Tung Nguyen +1
This study establishes a connection between the output-to-output gain (OOG), a sensitivity metric quantifying the impact of stealthy attacks, and a novel input-to-input gain (IIG)…
Bilateral Cognitive Security Games in Networked Control Systems under Stealthy Injection Attacks
Anh Tung Nguyen, Quanyan Zhu, André Teixeira
This paper studies a strategic security problem in networked control systems under stealthy false data injection attacks. The security problem is modeled as a bilateral cognitive s…
Data-Driven and Stealthy Deactivation of Safety Filters
Daniel Arnström, André M. H. Teixeira
Safety filters ensure that control actions that are executed are always safe, no matter the controller in question. Previous work has proposed a simple and stealthy false-data inje…
Risk assessment and optimal allocation of security measures under stealthy false data injection attacks
Sribalaji C. Anand, André M. H. Teixeira, Anders Ahlén
This paper firstly addresses the problem of risk assessment under false data injection attacks on uncertain control systems. We consider an adversary with complete system knowledge…
