Multi-criteria security assessment of control and diagnostic data on the technological processes

Abstract

A mathematical model of the dynamics of changes in the state of security indicators of control and diagnostic data on the technological process is proposed. It is constructed using Markov chains and takes into account the probabilistic-temporal mechanism for changing the state of data protection indicators of this class. Based on this model, a methodological approach has been developed for multi-criteria assessment of the security of control and diagnostic data on the technological process. The approach is based on the analysis of current deviations of the values of data protection indicators from the requirements for them, takes into account and eliminates the uncertainty of the initial diagnostic information. The proposed methodological approach also allows one to take into account transients that affect security when introducing control over the structure, parameters and modes of collection and processing of control and diagnostic data about the technological process in various conditions.

Assessment of components to ensure the security of control and diagnostic information about technological processes

“…In the modern world, much attention is paid to the problem of ensuring the security of information about technological processes (TP) [1][2][3]. At the same time, the task of ensuring the security of such information is aimed at obtaining accurate (reliable) and not distorted control and diagnostic data on the change in the state of TP security over time [4][5][6]. With the level of existing security threats and the growing number of attempts to maliciously influence information about TP, when it is possible to "throw" false data, or complex multi-step attacks from various categories of violators [7][8][9][10] are realized, this is especially important.…”
