TLDR
The deception attack presented here can enable remote water pilfering from automated canal systems and is reported on a field-operational test attack on the Gignac canal system located in Southern France.Abstract:
This brief aims to perform security threat assessment of networked control systems with regulatory and supervisory control layers. We analyze the performance of a proportional-integral controller (regulatory layer) and a model-based diagnostic scheme (supervisory layer) under a class of deception attacks. We adopt a conservative approach by assuming that the attacker has knowledge of: 1) the system dynamics; 2) the parameters of the diagnostic scheme; and 3) the sensor-control signals. The deception attack presented here can enable remote water pilfering from automated canal systems. We also report a field-operational test attack on the Gignac canal system located in Southern France.read more

Cyberattack-Resilient Hybrid Controller Design with Application to UAS
Cheolhyeon Kwon,Inseok Hwang +1 more
TL;DR: This work proposes a hybrid control framework containing multiple sub-controllers that can adapt to various cyberattacks by switching sub- Controllers, and the robustness of the controller is achieved by the switching logic which determines the safest sub-controller whose future performance under attack is the least bad.

False data injection attacks against state estimation in electric power grids
TL;DR: In this article, a new class of attacks, called false data injection attacks, against state estimation in electric power grids is presented and analyzed, under the assumption that the attacker can access the current power system configuration information and manipulate the measurements of meters at physically protected locations such as substations.

False data injection attacks against state estimation in electric power grids
TL;DR: A new class of attacks, called false data injection attacks, against state estimation in electric power grids are presented, showing that an attacker can exploit the configuration of a power system to launch such attacks to successfully introduce arbitrary errors into certain state variables while bypassing existing techniques for bad measurement detection.

Attacks against process control systems: risk assessment, detection, and response
TL;DR: By incorporating knowledge of the physical system under control, this paper is able to detect computer attacks that change the behavior of the targeted control system and analyze the security and safety of the mechanisms by exploring the effects of stealthy attacks, and by ensuring that automatic attack-response mechanisms will not drive the system to an unsafe state.
