Abstract The article is devoted to the solution of the practical problem of a quantitative assessment of the quality characteristic «usability» of information security systems against unauthorized access in automated systems in the secure version. The main operator who interacts with the information security system against unauthorized access during its operation is a security administrator. This interaction is carried out through the interface of the security program. Therefore, for this category of users, the most relevant assessment is the characteristic «usability» of the quality of functioning of the information security system against unauthorized access. The method of evaluating this characteristic involves assessment of the operation code, probabilistic and time indicators, based on the experiment. The obtained values of these indicators can be further used in the comparative analysis of the «usability» characteristic of information security systems against unauthorized access of various classes, during the development of work plans for information security services, and the justification of requirements for the organization and structure of information security services.
