The work is devoted to the study of methods for improving the quality of designing effective information protection systems. The paper proposes a method for monitoring the correct use of means of information protection available to the information protection system. To implement the method, an algorithm for calculating hash sums is used. A comparison of the performance of information protection systems using the proposed method and without it in the issue of introduced service delays for systems with phased servicing of incoming requests to the system is made. It is shown that the systems using this method are inferior in the introduced service delays. At the same time, it allows you to increase the degree of protection of the system from sophisticated information attacks by controlling the order of application of means of protection.
