Specification of Quality Indicators for Security Event and Incident Management in the Supply Chain

The paper proposes an approach to a formalized description of the process of changing the values of quality indicators of decision support for managing security events and incidents in the supply chain. The approach is based on the analysis of the functioning processes of modern quality control systems for information security in supply chain. In addition, it is based on an analysis of decision support processes. We use controlled Markov chains, represented by difference stochastic equations. The considered version of the analytical description of the state change in dynamics allows one to formalize, structure, and mathematically describe the process of this class from a uniform perspective. It is important to note that with this representation of the dynamics of state transitions, the requirements for operativity (timeliness), reliability, secrecy and resource costs for supporting decision-making to control information security in the supply chain are taken into account.
