“…Since the TA architecture considers issues across each OTI viewpoint, the inclusion or adaptation of any method that could support them was vital. While existing methods [23][24][25][26][27] provide interesting insight into the assessment of security, it appears some may face challenges when considering multiple OTI viewpoints. Through basic adaptation, the method in [28] appears to provide a good starting point.…”

Abstract-Utility networks are part of every nation's critical infrastructure, and their protection is now seen as a high priority objective. In this paper, we propose a threat awareness architecture for critical infrastructures, which we believe will raise security awareness and increase resilience in utility networks. We first describe an investigation of trends and threats that may impose security risks in utility networks. This was performed on the basis of a viewpoint approach that is capable of identifying technical and non-technical issues (e.g., behaviour of humans). The result of our analysis indicated that utility networks are affected strongly by technological trends, but that humans comprise an important threat to them. This provided evidence and confirmed that the protection of utility networks is a multi-variable problem, and thus, requires the examination of information stemming from various viewpoints of a network. In order to accomplish our objective, we propose a systematic threat awareness architecture in the context of a resilience strategy, which ultimately aims at providing and maintaining an acceptable level of security and safety in critical infrastructures. As a proof of concept, we demonstrate partially via a case study the application of the proposed threat awareness architecture, where we examine the potential impact of attacks in the context of social engineering in a European utility company.

“…Examples of the former category include fault-tolerant control (Blanke et al, 2003), resilient control (Mahmoud, 2004), and robust control of networked systems (Hespanha et al, 2007;Schenato et al, 2007). The latter category is a novel, rapidly expanding area of research, and some recent examples involve secure control (Cardenas et al, 2008;Mo and Sinopoli, 2009), and modeling of attacks and their impact (Kundur et al, 2011;Cam et al, 2014). Recently launched research initiatives, such as FORCEs (CPS-FORCES, 2015), aim to increase the understanding of how to design resilient large-scale, human-in-the-loop systems by combining tools from resilient control with economic incentive schemes.…”

Resilience through Learning in Multi-Agent Cyber-Physical Systems

et al. 2016

The paper contributes to the design of secure and resilient supervisory Cyber-Physical Systems (CPS) through learning. The reported approach involves the inclusion of learning modules in each of the supervised agents, and considers a scenario where the system's coordinator privately transmits to individual agents their action plans in the form of symbolic strings. Each agent's plans belong in some particular class of (sub-regular) languages, which is identifiable in the limit from positive data. With knowledge of the class of languages their plans belong to, agents can observe their coordinator's instructions and utilize appropriate Grammatical Inference modules to identify the behavior specified for them. From that, they can then work collectively to infer the executive function of their supervisor. The paper proves that in cases where the coordinator fails, or communication to subordinates is disrupted, agents are able not only to maintain functional capacity but also to recover normalcy of operation by reconstructing their coordinator. Guaranteeing normalcy recovery in supervisory CPSs is critical in cases of a catastrophic failure or malicious attack, and is important for the design of next-generation Cyber-Physical Systems.

“…This knowledge can be used to introduce security features step-by-step, starting with the most critical nodes in the system. Kundur et al (2011) presents a first step towards a graph-based framework for modeling the physical impact of cyber-attacks on smart grids. Two case studies show the application of the framework in a Matlab environment based on two modified models of the IEEE 13 node distribution system.…”

Cyber-security research in the field of smart grids is often performed with a focus on either the power and control domain or the Information and Communications Technology (ICT) domain. The characteristics of the power equipment or ICT domain are commonly not collectively considered. This work provides an analysis of the physical effects of cyber-attacks on microgrids -a smart grid construct that allows continued power supply when disconnected from a main grid. Different types of microgrid operations are explained (connected, islanded and synchronous-islanding) and potential cyber-attacks and their physical effects are analyzed. A testbed that is based on physical power and ICT equipment is presented to validate the results in both the physical and ICT domain.
