Models of socio-cyber-physical systems security

The development of technologies and computing resources has not only expanded the range of digital services in all spheres of human activity, but also determined the range of targeted cyber attacks. Targeted attacks are aimed at destroying not only the business structure, but also its individual components that determine critical business processes. The continuity of such business processes is a critical component of any company, organization or enterprise of any form of ownership, which has a critical impact on making a profit or organizing production processes. The proposed concept of determining the security level of critical business processes is based on the need to use multiloop information security systems. This makes it possible to ensure the continuity of critical business processes through a timely objective assessment of the level of security and the timely formation of preventive measures. This approach is based on the proposed rules for determining the reach of a given security level, based on assessments of the integrity, availability and confidentiality of information arrays, as well as computer equipment for different points of the organization's business processes. The issues of applying situational management methods to ensure the safe functioning of objects of socio-cyberphysical systems, logical and transformational rules that form the foundation for building a situational type cybersecurity management system are considered. One of the main tasks of systems of this type is described – the task of replenishing the description of the situation. The use of pseudophysical logics, various types of pseudophysical logics, the method of their construction and their interconnection are proposed. Particular attention is paid to causal pseudophysical logic, as the least developed for the purposes of ensuring cybersecurity. The formation of smart technologies, as a rule, uses the wireless standards of communication channels IEEE 802.11X, IEEE 802.15.4, IEEE 802.16, which use only authentication protocols and privacy mechanisms that are formed on the basis of symmetric algorithms. In the conditions of the post-quantum period (the appearance of a full-scale quantum computer), the stability of such algorithms is questioned. Such systems, as a rule, are formed on the basis of the synthesis of socio-cyber-physical systems and cloud technologies, which simplifies the implementation of Advanced Persistent Threat attacks, both on the internal loop of contr
