In order to assess quantitatively the protection of information on objects of informatization (OI) against leakage through channels of spurious electromagnetic radiation (SEMR), we propose to simulate the processes of interception of SEMR using the apparatus of Petri – Markov nets, which makes it possible to take into account the probabilistic-temporal characteristics of parallel processes of interception of such radiations arising in radio electronic devices (RED) of structural elements (SE) of an object, actions of a violator implementing interception from outside of the controlled area (CA), as well as protective measures aimed at preventing the possibility of intercepting SEMR. It is assumed that the energy and frequency characteristics of the SEMR allow a violator to carry out such an interception in the absence of protective measures. Indicators of assessment are given and analytical dependencies for their calculation are obtained. The model allows to assess the possibility of intercepting information related to confidential in time, as well as the impact of protective measures on the violator ability to intercept SEMR containing information of a confidential nature. We give examples of calculating the proposed indicators when analyzing the protection of voice information against interception by SEMR of RED of OI, and estimate the influence of preventive organizational and technical protection measures on reducing the possibilities of interception depending on the efficiency and timing of their implementation. Based on the performed computational experiment, we show that, when analyzing the protection of voice information against leakage by SEMR, it is necessary to evaluate not only the possibilities of energy detection of SEMR, but also the possibility of intercepting SEMR in time.
Keywords: information security indicator, spurious electromagnetic radiation, Petri–Markov net, preventive measures for information protection, technical channel of information leakage, time characteristics.
