Problem statement. The investigation the currently used methods for determining the sources of information leakage threats from the basic hardware and systems (BHaS) through the spurious electromagnetic radiation and interference (SERaB) channels on the object of informatization (OoI), gives grounds to assert that they have a number of disadvantages. The lack of а formal interpretation for process dynamics of the SERaB information collecting and implementing measures to prevent information leakage requires development of a systematic approach to improving the ways and means of protecting confidential information from leakage through SERaB channels.The purpose. Development of mathematical models and a systematic approach to improving methods and means of protecting confidential information from leaks through the SERaB channels from the BHaS on the OoI.Results. The article substantiates the need for a systematic approach to improving the methods and means of protecting confidential information from leakage through the SERaB channels from the BHaS on the OoI. The authors determined the ways of ensuring the adequacy of the methodological apparatus for the study of these technologies in order to justify measures to prevent leakage. They formulate requirements for techniques used to evaluate the characteristics of measures to prevent information leakage through the SERaB channels. There are describe the procedure of forming the mathematical models set structure for evaluating such characteristics. Also in the article are present the analytical models of the time characteristics of threats to intercept informative SERaB signals on the OoI and measures to prevent information leakage. Finally, the authors are justify the probabilistic format of the indicator of the effectiveness of such measures.Practical relevance. The developed mathematical models can be an effective tool for evaluating the characteristics of measures to prevent information leakage through the SERaB channels.
