“…The publications [19][20][21][22] are more theoretical. A discussion of the shortcomings of traditional security metrics is given in [19], the characteristics of «good» metrics are presented; security maturity models with examples are considered.…”

“…The topics discussed provide answers to questions about the theoretical aspects of the practical application of metrics in terms of «more or less» secure systems, as an approach to comparing the security of different systems. An increase in the level of theorization is presented in [20], where not only formal models of security measurement are presented, but also artificial intelligence methods are proposed for a wide range of applications. A brief description of risk as a security metric, alternative security metrics, and what constitutes a «good» metric can be found in [21].…”

“…The paper [36] discusses the software security properties that can be measured and proposes a number of software security properties along with related metrics. In [20], an approach to assessing the security of a software system being developed is proposed, security requirements are derived and a method for assessing the probability of violation of requirements based on individual risks of system components is given.…”

“…The average value of security service provision to CPSS information resources is calculated by the formula: (20) Table 10 shows the results of the average indicator of security service provision to CPSS information resources at the corresponding secrecy level of the asset. The results presented in Tables 9, 10 confirm the need for both strict accounting of information resources and definition of the «cost» (level of secrecy) of information resources.…”

The development of the IT industry and computing resources allows the formation of cyberphysical social systems (CPSS), which are the integration of wireless mobile and Internet technologies and the combination of the Internet of things with the technologies of cyberphysical systems. To build protection systems, while minimizing both computing and economic costs, various sets of security profiles are used, ensuring the continuity of critical business processes. To assess/compare the level of CPSS security, various assessment methods based on a set of metrics are generally used. Security metrics are tools for providing up-to-date information about the state of the security level, cost characteristics/parameters from both the defense and attack sides. However, the choice of such sets is not always the same/understandable to the average person. This, firstly, leads to the absence of a generally accepted and unambiguous definition, which means that one system is more secure than another. Secondly, it does not take into account the signs of synergy and hybridity of modern targeted attacks. Without this knowledge, it is impossible to show that the metric measures the security level objectively. Thirdly, there is no universal formal model for all metrics that could be used for rigorous analysis. The paper explores the possibility of defining a basic formal model (classifier) for analyzing security metrics. The proposed security assessment model takes into account not only the level of secrecy of information resources, the level of provision of security services, but also allows, based on the requirements put forward, forming the necessary set of security assessment metrics, taking into account the requirements for the continuity of business processes. The average value of the provision of security services to CPSS information resources is 0.99, with an average value of the security level of information resources of 0.8

“…Therefore, those systems need to be accurately designed and monitored in order to reduce the risk of malfunctions [ 2 ], possibly using agent-based approaches [ 3 , 4 ]. A class of those systems also needs to be certified against international well-established reliability, safety and security standards [ 5 , 6 ].…”

Digital twins as run-time predictive models for the resilience of cyber-physical systems: a conceptual framework

Digital twins (DT) are emerging as an extremely promising paradigm for run-time modelling and performability prediction of cyber-physical systems (CPS) in various domains. Although several different definitions and industrial applications of DT exist, ranging from purely visual three-dimensional models to predictive maintenance tools, in this paper, we focus on data-driven evaluation and prediction of critical dependability attributes such as safety. To that end, we introduce a conceptual framework based on autonomic systems to host DT run-time models based on a structured and systematic approach. We argue that the convergence between DT and self-adaptation is the key to building smarter, resilient and trustworthy CPS that can self-monitor, self-diagnose and—ultimately—self-heal. The conceptual framework eases dependability assessment, which is essential for the certification of autonomous CPS operating with artificial intelligence and machine learning in critical applications. This article is part of the theme issue ‘Towards symbiotic autonomous systems’.
