The Reliability of a Modular Information Security System in Instrument-making Enterprises 55_4.pdf

The article presents a modular approach to the design of information security system in an instrument-making enterprise. It is proposed to assess the reliability of the designed information security system in three stages. The method for evaluating the reliability of a modular information security system at a given amount of work performed in an instrument-making enterprise as well as a method for the system behavior evaluation when increasing the amount of work are described. Methods for assessment of the information security threat performance probability, the damage probability upon detection and non-detection of the performed threats as well as for the calculation of the system reliability are considered. The method for calculating the reliability of the modular information security system when performing of several similar tasks is presented. The importance of fragmentation of modules under the influence of security threats and the impact of this approach on the overall reliability of the system in an instrument-making enterprise are shown.
