Defense of Cyber Infrastructures Against Cyber Physical Attacks Using Game Theoretic Models Book Review:

The operation of cyber infrastructures relies on both cyber and physical components, which are subject to incidental and intentional degradations of different kinds. Within the context of network and computing infrastructures, we study the strategic interactions between an attacker and a defender using game-theoretic models that take into account both cyber and physical components. The attacker and defender optimize their individual utilities expressed as sums of cost and system terms. First, we consider a Boolean attack-defense model, wherein the cyber and physical sub-infrastructures may be attacked and reinforced as individual units. Second, we consider a component attack-defense model wherein their components may be attacked and defended, and the infrastructure requires minimum numbers of both to function. We show that the Nash equilibrium under uniform costs in both cases is computable in polynomial time, and it provides high-level deterministic conditions for the infrastructure survival. When probabilities of successful attack and defense, and of incidental failures are incorporated into the models, the results favor the attacker but otherwise remain qualitatively similar. This approach has been motivated and validated by our experiences with UltraScience Net infrastructure, which was built to support high-performance network experiments. In conclusion, the analytical results, however, are more general, and we apply them to simplified models of cloud and high-performance computing infrastructures.

Security and Privacy in Cyber Physical Systems Physical Attacks and Countermeasures Book Review:

The increasingly tight coupling of cyber (computing/communication) and physical (sensing/actuation) components has opened the door for developing many engineering systems with increasing complexity. On the one hand, these systems (commonly termed cyber-physical systems, or CPS for short) have enabled a multitude of applications where decisions are taken at various time-scales, driven by the sensory information, and are used for purposes such as automated control and adaptive interventions. On the other hand, there has been a corresponding increase in attacks targeting the integrity and security of these systems. These attacks pose a significant threat to often sensitive devices, potentially impairing our relation with these technologies. Various unique attributes of sensory information make it particularly challenging to formalize and address these concerns, and approaches thus far to handle them have been largely insufficient. The objective of this dissertation is to develop a principled understanding of these emerging concerns and develop formalisms, algorithms, and system mechanisms to effectively address them. The contributions of this dissertation are multi-fold. We start by playing the role of an adversarial attacker trying to discover new attack vectors for which traditional security mechanisms provide no defense guarantees. In particular, we focus on attacks that take place on sensors that collect information about the physical process in CPS. We show that by exploiting the weakness in securing sensor information, a malicious attacker can cause life-threatening situations which plays as a motivation for the rest of this dissertation. Next, we explore two countermeasures called sensor-level countermeasures and system-level countermeasures. In the sensor-level countermeasures, we propose a physical challenge-response authentication (PyCRA) scheme for sensors that is designed to provide an authorization mechanism that not only detects malicious attacks but provides resilience against them. The majority of this dissertation focuses on designing system-level counter measures to sensor attacks. In the system-level countermeasures, we consider the problem of designing algorithms for CPS whose sensor measurements are corrupted by a malicious attacker. The attacker capabilities are limited in the sense that only a subset of all the sensors can be attacked although this subset is unknown. In particular, we focus on the setup where all measurements from various sensors are sent to a central unit whose functionality is to fuse all these measurements in order to estimate the state of the CPS regardless of the existence of the malicious attacker. We call this problem the secure state estimation problem. We analyze sufficient and necessary conditions for the solvability of the secure state estimation problem under three different setups namely, linear deterministic systems, linear stochastic systems, and nonlinear deterministic systems. We propose the notion of s-sparse observability and show how it plays a vital role in solving the secure state estimation problem. We show that the secure state estimation problem is a combinatorial problem. The most notable contribution of this dissertation is a novel Satisfiability Modulo Theory (SMT) solver that splits the reasoning, about the combinatorial complexity of the secure state estimation problem, over Boolean and real domains and uses a powerful tool from each domain. By leveraging results from formal methods over real numbers, we provide guarantees on the soundness and completeness of our algorithm. We also extend the SMT-solver to estimate the state under sensor attacks to the context of stochastic linear dynamical system and nonlinear differentially flat systems Finally, we touch upon the related problem of privacy attacks in cyber-physical systems. Unlike sensor attacks, privacy attacks are a form of passive attacks that target data collection that can be used to leak sensitive information. We present a novel model-based obfuscation approach with strong formal guarantees. Our approach preserves both the utility of the event trace and its spatio-temporal-plausibility while providing strong privacy guarantees.

Cyber Physical Attack Defenses Book Review:

What is a cyber-physical attack? A cyber-physical attack is one in which a wholly digital attack against Cyber-Physical Systems (CPS) caused physical destruction of equipment. A cyber-physical attack is different from an enterprise network attack designed to steal money, exfiltrate information, or hold a computer hostage for ransom. Those attacks are fairly simple and can be carried out by a cyber-criminal, or even a garden variety cracker. Designing an attack scenario to exploit a particular physical process requires a solid engineering background and in-depth destructive knowledge of the target SCADA system (Cyber-Physical Attack Engineering), but a cracker doesn't need an engineering background to figure out how to turn equipment off. Basically, it's the weaponization of the Internet. A typical Industrial Controls System contains multiple control loops and sometimes the control loops are nested and/or cascading, so the set point for one loop is based on the process variable output from another loop. Supervisory control loops and lower-level loops operate continuously over the duration of a process with cycle times of milliseconds. Interrupting one process can have a ripple effect through the factory. So, what is the big deal? On December 3 1984, in Bhopal, India there was an industrial accident at a pesticide plant that immediately killed at least 3,800 people and caused significant morbidity and premature death for many thousands more. That was only one incident with a release of only 40 tons of methyl isocyanate gas. Of course, this was an accident and not a cyber-physical attack, but it should give you an idea what could happen in a worst-case scenario. Imagine you wake up in the morning and go the bathroom. You turn on the faucet and nothing happens. You go back to the bedroom and the clock is flashing 12:00. You hit the power button on the TV remote and nothing happens. It's a little warm in the house, but the air conditioning won't work. Then you realize that though the sun is out and it's a normal weekday, you don't hear any cars going by. You go outside to your car and it won't start. The cell phone has no signal and won't stay on when you power up. The toaster doesn't heat up and you have to light the gas stove with a match. It's a nice day so you walk to work and notice a line outside the supermarket, but the doors are locked. You ask why they don't open up and they say there is no power to run the cash registers. Even their backup generator won't start. None of the traffic lights work, but there are no cars on the road anyway. This is a cyber-physical attack that affects all utilities and electronic devices.

Security of Cyber Physical Systems Book Review:

This book presents a comprehensive overview of security issues in Cyber Physical Systems (CPSs), by analyzing the issues and vulnerabilities in CPSs and examining state of the art security measures. Furthermore, this book proposes various defense strategies including intelligent attack and anomaly detection algorithms. Today’s technology is continually evolving towards interconnectivity among devices. This interconnectivity phenomenon is often referred to as Internet of Things (IoT). IoT technology is used to enhance the performance of systems in many applications. This integration of physical and cyber components within a system is associated with many benefits; these systems are often referred to as Cyber Physical Systems (CPSs). The CPSs and IoT technologies are used in many industries critical to our daily lives. CPSs have the potential to reduce costs, enhance mobility and independence of patients, and reach the body using minimally invasive techniques. Although this interconnectivity of devices can pave the road for immense advancement in technology and automation, the integration of network components into any system increases its vulnerability to cyber threats. Using internet networks to connect devices together creates access points for adversaries. Considering the critical applications of some of these devices, adversaries have the potential of exploiting sensitive data and interrupting the functionality of critical infrastructure. Practitioners working in system security, cyber security & security and privacy will find this book valuable as a reference. Researchers and scientists concentrating on computer systems, large-scale complex systems, and artificial intelligence will also find this book useful as a reference.

Using a Systems theoretic Approach to Analyze Cyber Attacks on Cyber physical Systems Book Review:

With increased Internet connectivity and the advent of the industrial Internet, cyber-physical systems are increasingly being targeted by cyber attacks. Unlike, cyber attacks on IT networks, successfully compromising a cyber-physical environment takes considerably more time, motivation, expertise, and operational costs to the adversary. This thesis explores how a systems-theoretic approach, the Systems-Theoretic Accident Model and Processes (STAMP), can be used by an organization to complement intelligence-driven models of intrusion analysis to provide both additional insight and prioritize defensive countermeasures in order to guard against cyber-physical attacks and compromises. Specifically, in this thesis we analyze two real-world use cases of well publicized cyber-physical attacks using traditional intelligence-driven models of intrusion analysis as well as apply the Causal Analysis based on STAMP (CAST) model on one of the use cases. The STAMP/CAST based analysis afforded us deeper insights into the system causal factors that led to the successful compromise. In turn, this allowed for the generation of specific recommendations to safeguard the cyber-physical systems within the network in order to increase the overall organizational security posture. This included a recommendation to modify the existing organizational structure (i.e., the addition of a Security Operations Centre function) such that clearly defined security roles and responsibilities could be effectively implemented thus significantly improving an organization's ability to respond to cyber attacks.

Resilient and Safe Control of Cyber physical Systems Under Uncertainties and Adversaries Book Review:

The recent growth of cyber-physical systems with a wide range of applications such as smart grids, healthcare, search and rescue and traffic monitoring, to name a few, brings new challenges to control systems due to the presence of significant uncertainties and undesired signals (i.e., disturbances and cyber-physical attacks). Thus, it is of vital importance to design resilient and safe control approaches that can adapt to the situation and mitigate adversaries to ensure an acceptable level of functionality and autonomy despite uncertainties and cyber-physical attacks.This dissertation begins with the analysis of adversaries and design of resilient distributed control mechanisms for multi-agent cyber-physical systems with guaranteed performance and consensus under mild assumptions. More specifically, the adverse effects of cyber-physical attacks are first analyzed on the synchronization of the multi-agent cyber-physical systems. Then, information-theoretic based detection and mitigation methods are presented by equipping agents with self-belief about the trustworthiness of their own information and trust about their neighbors. Then, the effectiveness of the developed approach is certified by applying it to distributed frequency and voltage synchronization of AC microgrids under data manipulation attacks. In the next step, to relax some connectivity assumptions in the network for the resilient control design, a distributed adaptive attack compensator is developed by estimating the normal expected behavior of agents. The adaptive attack compensator is augmented with the controller and it is shown that the proposed controller achieves resilient synchronization in the presence of the attacks on sensors and actuators. Moreover, this approach recovers compromised agents under actuator attacks and avoids propagation of attacks on sensors without discarding information from the compromised agents. Then, the problem of secure state estimation for distributed sensor networks is considered. More specifically, the adverse effects of cyber-physical attacks on distributed sensor networks are analyzed and attack mitigation mechanism for the event-triggered distributed Kalman filter is presented. It is shown that although event-triggered mechanisms are highly desirable, the attacker can leverage the event-triggered mechanism to cause triggering misbehaviors which significantly harms the network connectivity and performance. Then, an entropy estimation-based attack detection and mitigation mechanisms are designed.Finally, the safe reinforcement learning framework for autonomous control systems under constraints is developed. Reinforcement learning agents with pre-specified reward functions cannot provide guaranteed safety across variety of circumstances that an uncertain system might encounter. To guarantee performance while assuring the satisfaction of safety constraints across variety of circumstances, an assured autonomous control framework is designed by empowering reinforcement learning algorithms with meta-cognitive learning capabilities. More specifically, adapting the reward function parameters of the reinforcement learning agent is performed in a meta-cognitive decision-making layer to assure the feasibility of the reinforcement learning agent.

Baiting for Defense Against Stealthy Attacks on Cyber physical Systems Book Review:

The goal of this thesis is to develop a defense methodology for a cyber-physical system (CPS) by which an attempted stealthy cyber-attack is detected in near real time. Improvements in networked communication have enabled vast and complex dynamic control systems to exploit networked control schemes to seamlessly integrate parts and processes. These cyber-physical systems exhibit a level of flexibility that was previously unavailable but also introduce communication channels that are vulnerable to outside interference and malicious intervention. This thesis considers the effects of a type of stealthy attack on a class of CPS that can be modeled as linear time-invariant systems. The effects of this attack are studied from both the perspective of the attacker as well as the defender. A previously developed method for conducting stealthy attacks is introduced and analyzed. This method consists of injecting malicious actuation signals into the control input of a CPS and then designing a sensor attack to conceal the effect of the actuator attack. The result is an attack that cannot be detected upon inspection of the Kalman filter residual. Successful implementation of this attack is shown to require the attacker to attain perfect model knowledge in order for the attack to be stealthy. Based on the execution of past attacks on CPS, this thesis proposes an attacker who starts their attack by "fishing" for critical and confidential system information such as the model parameters. A method is then proposed in which the defender attempts to feed the attacker a slightly falsified model, baiting the fishing attacker with data that will make an attack detectable. Because the attacker's model is no longer correct, their attack design will induce a mean-shift in the Kalman filter residual, breaking the stealthiness of the original attack formula. It is then shown that the defender can not only detect this faulty attack, but use observations of the Kalman filter residual to regain more accurate state estimates, mitigating the effect of the attack.

Securing Cyber Physical Systems Book Review:

Think about someone taking control of your car while you're driving. Or, someone hacking into a drone and taking control. Both of these things have been done, and both are attacks against cyber-physical systems (CPS). Securing Cyber-Physical Systems explores the cybersecurity needed for CPS, with a focus on results of research and real-world deployment experiences. It addresses CPS across multiple sectors of industry. CPS emerged from traditional engineered systems in the areas of power and energy, automotive, healthcare, and aerospace. By introducing pervasive communication support in those systems, CPS made the systems more flexible, high-performing, and responsive. In general, these systems are mission-critical—their availability and correct operation is essential. This book focuses on the security of such mission-critical systems. Securing Cyber-Physical Systems brings together engineering and IT experts who have been dealing separately with these issues. The contributed chapters in this book cover a broad range of CPS security topics, including: Securing modern electrical power systems Using moving target defense (MTD) techniques to secure CPS Securing wireless sensor networks (WSNs) used for critical infrastructures Mechanisms to improve cybersecurity and privacy in transportation CPS Anticipated cyberattacks and defense approaches for next-generation autonomous vehicles Security issues, vulnerabilities, and challenges in the Internet of Things Machine-to-machine (M2M) communication security Security of industrial control systems Designing "trojan-resilient" integrated circuits While CPS security techniques are constantly evolving, this book captures the latest advancements from many different fields. It should be a valuable resource for both professionals and students working in network, web, computer, or embedded system security.

Handbook on Securing Cyber Physical Critical Infrastructure Book Review:

The worldwide reach of the Internet allows malicious cyber criminals to coordinate and launch attacks on both cyber and cyber-physical infrastructure from anywhere in the world. This purpose of this handbook is to introduce the theoretical foundations and practical solution techniques for securing critical cyber and physical infrastructures as well as their underlying computing and communication architectures and systems. Examples of such infrastructures include utility networks (e.g., electrical power grids), ground transportation systems (automotives, roads, bridges and tunnels), airports and air traffic control systems, wired and wireless communication and sensor networks, systems for storing and distributing water and food supplies, medical and healthcare delivery systems, as well as financial, banking and commercial transaction assets. The handbook focus mostly on the scientific foundations and engineering techniques – while also addressing the proper integration of policies and access control mechanisms, for example, how human-developed policies can be properly enforced by an automated system. Addresses the technical challenges facing design of secure infrastructures by providing examples of problems and solutions from a wide variety of internal and external attack scenarios Includes contributions from leading researchers and practitioners in relevant application areas such as smart power grid, intelligent transportation systems, healthcare industry and so on Loaded with examples of real world problems and pathways to solutions utilizing specific tools and techniques described in detail throughout

Cross Layer Design for Secure and Resilient Cyber Physical Systems Book Review:

This book introduces a cross-layer design to achieve security and resilience for CPSs (Cyber-Physical Systems). The authors interconnect various technical tools and methods to capture the different properties between cyber and physical layers. Part II of this book bridges the gap between cryptography and control-theoretic tools. It develops a bespoke crypto-control framework to address security and resiliency in control and estimation problems where the outsourcing of computations is possible. Part III of this book bridges the gap between game theory and control theory and develops interdependent impact-aware security defense strategies and cyber-aware resilient control strategies. With the rapid development of smart cities, there is a growing need to integrate the physical systems, ranging from large-scale infrastructures to small embedded systems, with networked communications. The integration of the physical and cyber systems forms Cyber-Physical Systems (CPSs), enabling the use of digital information and control technologies to improve the monitoring, operation, and planning of the systems. Despite these advantages, they are vulnerable to cyber-physical attacks, which aim to damage the physical layer through the cyber network. This book also uses case studies from autonomous systems, communication-based train control systems, cyber manufacturing, and robotic systems to illustrate the proposed methodologies. These case studies aim to motivate readers to adopt a cross-layer system perspective toward security and resilience issues of large and complex systems and develop domain-specific solutions to address CPS challenges. A comprehensive suite of solutions to a broad range of technical challenges in secure and resilient control systems are described in this book (many of the findings in this book are useful to anyone working in cybersecurity). Researchers, professors, and advanced-level students working in computer science and engineering will find this book useful as a reference or secondary text. Industry professionals and military workers interested in cybersecurity will also want to purchase this book.
