Innovative activity of universities and the formation of entrepreneur universities of the innovative type is one of the forms of integration of the higher education systems of countries into the world educational and scientific space, support of their competitiveness. Based on the separation of interaction between universities and the economy and society, an evolutionary model of the university's interaction with stakeholders was developed. Understanding the new mission of universities made it possible to separate the dominants of activities of an innovative and active university (IAU), to develop a scheme of the interconnection of management processes and its basic functions. The authors' interpretation of the IAU and the preconditions for constructing a corporate information and education system (CIES) was formed. Given the synergism and hybridity of modern cyber threats, the rise of corruption in the educational sphere, the Anti-corruption concept, which provides countering the elements of corruption and integrated hybrid threats through the construction of an adaptive information protection system (AIPS). The basis of corruption counteraction is the digital signature (DS) of the Key Certification Center (KCC) based on PKI (Public Key Infrastructure). To ensure the security of information resources (IR) of CIES, we proposed a model that makes it possible not only to take into consideration the synergy and hybridity of modern threats but also to form preventive anti-corruption measures. A model for providing anti-corruption measures that reflects the scenarios of the behavior of the participants of the corruption process and the anti-corruption bodies was developed. This makes it possible to assess the dynamics of the distribution of corruption deals over time and by the types of corruption to ensure the effective distribution of the university resources for anti-corruption activities

“…Simulation of models: "predatorprey" taking into account the computing capabilities and focus of targeted cyberattacks, "predator-prey" taking into account the possible competition of attackers in relation to the "prey", "predator-prey" taking into account relationships between "prey species" and "predator species", "predator-prey" taking into account relationships between "prey species" and "predator species" using a Java Script software package presented on the web resource [27]. In the expert assessment of threats ((https:// bdu.fstec.ru/threat) [28], weighting factors of expert competence are proposed for the objectivity of expert judgments. The selection of experts from the scientific community is based on the analysis of publications in science-metric databases, research directions, as well as practical examination experience.…”

The paper presents the results of the development of a method for assessing the security of cyber-physical systems based on the Lotka–Volterra model. Security models of cyber-physical systems are proposed: “predator–prey” taking into account the computing capabilities and focus of targeted cyberattacks, “predator–prey” taking into account the possible competition of attackers in relation to the “prey”, “predator–prey” taking into account the relationships between “prey species” and “predator species”, “predator–prey” taking into account the relationship between “prey species” and “predator species”. Based on the proposed approach, the coefficients of the Lotka–Volterra model α=0.39, β=0.32, γ=0.29, φ=0.27 were obtained, which take into account the synergy and hybridity of modern threats, funding for the formation and improvement of the protection system, and also allow determining the financial and computing capabilities of the attacker based on the identified threats. The proposed method for assessing the security of cyber-physical systems is based on the developed threat classifier, allows assessing the current security level and provides recommendations regarding the allocation of limited protection resources based on an expert assessment of known threats. This approach allows offline dynamic simulation, which makes it possible to timely determine attackers' capabilities and form preventive protection measures based on threat analysis. In the simulation, actual bases for assessing real threats and incidents in cyber-physical systems can be used, which allows an expert assessment of their impact on both individual security services and security components (cyber security, information security and security of information). The presented simulation results do not contradict the graphical results of the classical Lotka–Volterra model, which indicates the adequacy of the proposed approach for assessing the security of cyber-physical systems

“…However, for it to function at the current rate of development of computing resources, and given the growth (modification) of cyberthreats seeking to be integrated with social engineering methods, it is necessary to consider the possible scenarios of their impact on the internal OT-infrastructure of CPPS. Paper [15] proposes using the following classification of cyberthreats to the cyber-physical and information-switching systems, which are the basis of CPPS, shown in Fig. 3.…”

Development of an architectural-logical model to automate the management of the process of creating complex cyber-physical industrial systems

Modern highly technological production puts forward new requirements and approaches to the implementation of the Industry 4.0 concept. To achieve this, it is necessary to develop a cyber-physical production system that would make it possible to fully take into consideration all the factors of the actual production system. All solutions must pursue the global goal of making the best use of production time and resources, as well as meet the "Lean Production" concept. Existing ISO-95, 5C, and 8C cyber-physical production systems (CPPS) reference architectures cannot provide clearly expressed systematization and detailing. Such systems are a set of general recommendations that show the interaction processes among the physical and cyber-components of CPPS. This paper reports a new approach to the systemic representation of the processes for managing the development of complex cyber-physical production systems in the face of today's threats. We have suggested a systemic representation of automating the process of managing the development of complex CPPS. Modern threats to the cyber-physical and information and communication systems (ICS) have been considered, which underlie CPPS. An architectural-logical model, as well as methods for automating the CPPS development process management, have been developed. This could help build a logical relationship from the initial "target" stage to the process of obtaining "management algorithms" at each level and stage of CPPS development as a symbiosis of physical and cyber-components. The devised CPPS development process management model provides an opportunity to propose a group of mathematical models and methods that logically link all development stages into a single "rigid" hierarchical sequence. This makes it possible to build a single information space with a set of complex CPPS development methodology. The proposed solutions could enable the development of an automated system to manage the process of the development of complex CPPS
