Distributionally Robust Tuning of Anomaly Detectors in Cyber-Physical Systems with Stealthy Attacks
Venkatraman Renganathan, Navid Hashemi, Justin Ruths +1
Designing resilient control strategies for mitigating stealthy attacks is a crucial task in emerging cyber-physical systems. In the design of anomaly detectors, it is common to ass…
Community Detection via Katz and Eigenvector Centrality
Mark Ditsworth, Justin Ruths
The computational demands of community detection algorithms such as Louvain and spectral optimization can be prohibitive for large networks. Eigenvector centrality and Katz central…
Filtering Approaches for Dealing with Noise in Anomaly Detection
Navid Hashemi, Eduardo Verdugo German, Jonatan Pena Ramirez +1
The leading workhorse of anomaly (and attack) detection in the literature has been residual-based detectors, where the residual is the discrepancy between the observed output provi…
Generalized chi-squared detector for LTI systems with non-Gaussian noise
Navid Hashemi, Justin Ruths
Previously, we derived exact relationships between the properties of a linear time-invariant control system and properties of an anomaly detector that quantified the impact an atta…
Co-design for Security and Performance: LMI Tools
Navid Hashemi, Justin Ruths
We present a convex optimization to reduce the impact of sensor falsification attacks in linear time invariant systems controlled by observer-based feedback. We accomplish this by…
