Research on the assessment of the risk situations emergence for automated control systems of the metallurgical industry companies

emergence based on the analysis of the probability and frequency of
threats emergence for automated control systems of the metallurgical
industry companies (ACSMIC). The analysis of the risk dependency
on vulnerabilities and threats to ACSMIC assets is carried out, and
the relationship between risk, vulnerability, and threat is presented
according to a three-level risk assessment scale. When identifying
and assessing the risk, existing countermeasures against both external
and internal attacks are taken into account, which, in turn, reduces the
risk level for the protected organization. In the process of any
organization functioning, there may be a need to reassess the risk
associated with changes in the structure of the control organization
or security policy in the system of the metallurgical industry
companies. Therefore, the existing countermeasures are closely
related to the concept of risk and require constant correction in the
assessment process. Risk is related to the reliability of the functioning
of the studied control structure of units and aggregates and their
ability to function in accordance with the mode and goals of the
production structure in various branches and levels of the hierarchy
with an acceptable risk assessment. On the basis of the system
concepts and assessment methods of the acceptable risk level, the
system-oriented method of identifying the reliability of functioning
of self-recovering complex hierarchical structures is proposed, the
classification of the risk types of unforeseen situations in complex
human-oriented systems that can be applied and implemented in
hierarchical control systems is carried out.
