Developing a Hybrid Intrusion Detection System Using Data Mining for Power Systems
TL;DR: A systematic and automated approach to build a hybrid IDS that learns temporal state-based specifications for power system scenarios including disturbances, normal control operations, and cyber-attacks is presented.
Proceedings ArticleDOI
Machine learning for power system disturbance and cyber-attack discrimination
Raymond C. Borges Hink,Justin M. Beaver,Mark A. Buckner,Thomas Morris,Uttam Adhikari,Shengyi Pan +5 more
TL;DR: This work explores the viability of machine learning as a means for discriminating types of power system disturbances, and focuses specifically on detecting cyber-attacks where deception is a core tenet of the event.
Journal ArticleDOI
Modeling Cyber-Physical Vulnerability of the Smart Grid With Incomplete Information
Anurag K. Srivastava,Thomas Morris,Timothy A. Ernster,Ceeman B. Vellaithurai,Shengyi Pan,Uttam Adhikari +5 more
TL;DR: This paper addresses the attack modeling using vulnerability of information, communication and electric grid network using graph theory based approach and shows the possible impact on smart grid caused by integrated cyber-physical attack.
Journal ArticleDOI
Classification of Disturbances and Cyber-Attacks in Power Systems Using Heterogeneous Time-Synchronized Data
TL;DR: A sequential pattern mining approach to accurately extract patterns of power-system disturbances and cyber-attacks from heterogeneous time-synchronized data, including synchrophasor measurements, relay logs, and network event monitor logs is proposed.
Journal ArticleDOI
WAMS Cyber-Physical Test Bed for Power System, Cybersecurity Study, and Data Mining
TL;DR: A WAMS cyber-physical test bed is developed capable of simulating various sized power systems and creating datasets without altering the hardware configuration and a WAMS architecture is presented to document the integration of various components.
