Titova The article presents key performance indicators of information security systems and methods of their determination. Classification and methods of calculation of complex performance indicators are given and also determination of the complex weighted average of efficiency assessment. The conditions under which the application of the weighted average complex indicator of efficiency assessment for the selected information security system is carried out are determined. The integral indicator reflecting a ratio of total useful effect from operation and total expenses for its creation and operation is also presented Keywords: information; performance indicators of information security systems; weighted average evaluation of the effectiveness systems; effect of the operation.
