Towards Cyber-Physical Security for Additively Manufactured Parts via In Situ Monitoring and Electromechanical Impedance
… entirely by computer controlled machines and cyber-domain data, the AM process is uniquely at risk of nearly undetectable cyber-physical attacks, or cyber attacks that can cause physical damage. Additionally, as much of the valuable intellectual property associated with the design and material …

Strategic and analytics-driven inspection operations for critical infrastructure resilience
… However, recent natural disasters and cyber-physical security attacks have demonstrated that the lack of effective failure detection and identification capabilities is one of the main contributors of economic losses and safety risks faced by service utilities. This thesis focuses on …

A Hands-on Modular Laboratory Environment to Foster Learning in Control System Security
Cyber-Physical Systems (CPSes) form the core of Industrial Control Systems (ICS) and critical infrastructures. These systems use computers to control and monitor physical processes in many critical industries including aviation, industrial automation, transportation, communications, waste …

Communication scheduling and remote estimation with additive noise channels
Communication scheduling and remote estimation scenarios arise in the context of wireless sensor networks, which involve monitoring and controlling the state of a dynamical system from remote locations. This entails joint design of transmission and estimation policies, where a sensor (or a group of …

A Multi-Agent Defense Methodology with Machine Learning against Cyberattacks on Distribution Systems
… has rendered the power grid vulnerable to cyberattacks. In December 2015, over 200,000 people in Ukraine became victims of the first publicly reported cyberattack on the power grid. Consequently, cyber-physical security research for the power system as a critical infrastructure is in …

Impact evaluation of cyber-physical uncertainty on power systems
… system performance of uncertainty arising from physical and cyber components of power systems. If the impact of the uncertainty arising from emerging technologies is not fully understood, it will likely lead to the deployment of unreliable and unsafe systems, which could have catastrophic …

A Physical Hash for Preventing and Detecting Cyber-Physical Attacks in Additive Manufacturing Systems
… proposes a new method for detecting malicious cyber-physical attacks on additive manufacturing (AM) systems. The method makes use of a physical hash, which links digital data to the manufactured part via a disconnected side-channel measurement system. The disconnection ensures that if the …

Real-time Adaptive Sensor Attack Detection and Recovery in Autonomous Cyber-physical Systems
<p>Cyber-Physical Systems (CPS) tightly couple information technology with physical processes, which rises new vulnerabilities such as physical attacks that are beyond conventional cyber attacks.Attackers may non-invasively compromise sensors and spoof the controller to perform unsafe actions. This …

Logic-Targeted Data Poisoning and Cascading Failures in AI-Driven Distributed Traffic Control Systems
… people and vehicles, but it also introduces new physical-layer safety risks at the sensor level that have not been studied suffciently. This thesis introduces the False Vacuum Attack, where one compromised sensor continuously reports “0” vehicles while the true intersection queue continues to …

Exploring the Vulnerabilities of Traffic Collision Avoidance Systems (TCAS) Through Software Defined Radio (SDR) Exploitation
… means for more investigation into TCAS from a security perspective. Methods for analyzing TCAS both qualitatively and quantitatively from an adversarial perspective are presented, and an experimental attack is developed in GNU Radio to perform an attack in a well-defined threat model.
