Adversary-driven state-based system security evaluation
… in making informed trade-off decisions. In system-level security decisions, quantitative security metrics allow decision-makers to compare the relative security of different system configurations. To produce model-based quantitative security metrics, we have formally defined and implemented …

An Educational Framework to Support Industrial Control System Security Engineering
Industrial Control Systems (ICSs) are used to monitor and control critical infrastructure such as electricity and water. ICS were originally stand-alone systems, but are now widely being connected to corporate national IT networks, making remote monitoring and more timely control possible. While …

Record and replay based virtual-machine introspection for system security
Hardware security features need to strike a careful balance between design intrusiveness and completeness of methods. Securing against attacks like Return Oriented Programming (ROP) requires frequent and expensive checks. Complete security defenses have been proposed yet modern systems are still …

Electric ship digital twin : framework for cyber-physical system security
… However, a cyberattack on a networked control system presents not just the possibility of information theft but of physical system damage and loss of control. Thus, a detection scheme is proposed for cyber-physical systems using a joint unscented Kalman filter. It is employed to detect …

Improving Operating System Security, Reliability, and Performance through Intra-Unikernel Isolation, Asynchronous Out-of-kernel IPC, and Advanced System Servers
Computer systems are vulnerable to security exploits, and the security of the operating system (OS) is crucial as it is often a trusted entity that applications rely on. Traditional OSs have a monolithic design where all components are executed in a single privilege layer, but this design is …

THE PROGRAM PATHING TRUST MODEL FOR CRITICAL SYSTEM PROCESS AUTHORIZATION
… – the concept of a “trusted” or tamperproof system has become even more important. Some applications have become so critical that it is imperative that they run as intended, without interference. The consequences of these systems not running as intended could be catastrophic. This research …
