Security monitoring of computerized boiler rooms with network access and risk assessment on a logicalprobabilistic model

Abstract

We consider one of the existing technologies, scilicet of the multi-shift safety monitoring, which implies tracking of the integrity of the information system (IS) by periodically replacing each other operators in the interval between diagnostics of the system, in relation to computerized boiler-rooms with network access. Herein the IS of the boiler-house is taken into account as protected from dangerous software-engineering influences through the computer network only if to the beginning of the specified period of time the integrity of the system is ensured and throughout this set period the sources of danger do not penetrate the system (with a calculated probability). Here the operator of the boiler-room figures as an eventual link of the series of the controlled, including the program level, barriers for (external) network malefactor. For computerized boiler-houses, depending on the ratios for the duration of the operator’s work during each shift, the specified period of safe operation and the period between diagnostics, three variants are considered that are typical for this technology. The possibilities of applying the latter in the foreshortening of risk assessment of emergency situations (ES) within the previously developed by the author logical-probabilistic model for computerized boiler-houses are discussed.
