MATHEMATICAL MODEL OF INFORMATION SECURITY’S THEAT AGENT

To provide information security in automated control systems, the construction of an effective system of information security, it was not enough to identify channels of information leakage, to analyze the possible threats, the consequences of their implementation and estimate the losses. It is necessary to imagine an offender even better. An offender model is one of the most important components of a possible scenario for unlawful actions on access to information. The existence of such a model of a security breach, which is constantly corrected on the basis of obtaining new knowledge about the possibilities of the offender and changes in the security system, based on an analysis of the causes of violations, will allow themselves to affect these reasons, as well as more precisely define the requirements for the information security system from this type of violations. Correctly constructed model of the violator of information security, (adequate to reality), which reflects his practical and theoretical capabilities, a priori knowledge, time and place of action, etc. characteristics are an important part of a successful risk analysis and the definition of requirements for the composi
