METHOD FOR QUANTITATIVE ASSESSMENT OF THE LEVEL OF OPERATING SYSTEM RESISTANCE TO CONFIDENTIAL INFORMATION LEAKAGE

Abstract

It is often necessary to determine which of the complex systems is better, has a higher level when solving a certain type of problem. At the same time, the reliability should be as high as possible, because the price of the issue can be quite high. In our case, such a task is to ensure the OS a high level of stability of the information system operating under its control, to prevent the leakage of confidential information.

When conducting comparative analyses of any complex systems in general, or their individual subsystems, a question arises, the answer to which is completely non-trivial. In such conditions, it is practically impossible to get an unambiguous answer to such a question, especially when it comes to used, operating systems.

A system or part of it that would be clearly worse than other systems in all respects simply could not exist. In reality, a typical multi-criteria problem occurs when there are several selected quality criteria by which the compared systems should be evaluated, as well as a certain set of systems that are ahead of each other by some criteria and, usually, inferior by others.

Therefore, finding a method for solving such problems is a promising direction of research and a relevant scientific problem.

The paper proposes to improve the known method in order to increase its sensitivity and use it for quantitative assessment of compared complex software systems.

The directions of further research will be to expand the class of problems solved by it.
