Cyber-security of SCADA systems
Innovative Smart Grid Technologies, IEEE PES
By Goran Andersson,Peyman Mohajerin Esfahani,Maria Vrakopoulou,Kostas Margellos,John Lygeros,Andre Teixeira,Gyorgy Dan,Henrik Sandberg,Karl H. Johansson
Issue Date:January 2012
After a general introduction of the VIKING EU FP7 project two specific cyber-attack mechanisms, which have been analyzed in the VIKING project, will be discussed in more detail. Firstly an attack and its consequences on the Automatic Generation Control (AG...
Challenges in Power System Information Security
IEEE Security & Privacy Magazine
By György Dán,Henrik Sandberg,Mathias Ekstedt,Gunnar Björkman
Issue Date:July 2012
Achieving all-encompassing component-level security in power system IT infrastructures is difficult, owing to its cost and potential performance implications.
Active actuator fault detection and diagnostics in HVAC systems
Found in: Proceedings of the Fourth ACM Workshop on Embedded Sensing Systems for Energy-Efficiency in Buildings (BuildSys '12)
By Dario Papale, Francesca Madia Mele, Henrik Sandberg, Iman Shames, James Weimer, José Araujo, Karl Henrik Johansson, Seyed Alireza Ahmadi
Issue Date:November 2012
This paper introduces a new method for performing actuator fault detection and diagnostics (FDD) in heating ventilation and air conditioning (HVAC) systems. The proposed actuator FDD strategy, for testing whether an actuator is stuck in a single position, ...
Attack models and scenarios for networked control systems
Found in: Proceedings of the 1st international conference on High Confidence Networked Systems (HiCoNS '12)
By Daniel Perez, Karl Henrik Johansson, Andre Teixeira, Henrik Sandberg
Issue Date:April 2012
Cyber-secure networked control is modeled, analyzed, and experimentally illustrated in this paper. An attack space defined by the adversary's system knowledge, disclosure, and disruption resources is introduced. Adversaries constrained by these resources a...
