Assessment of information losses level due to adverse electromagnetic radiation

Abstract

In the process of building complex systems of information protection of corporate networks is necessary to analyze and evaluate possible losses due to stray electromagnetic radiation from various sources. Currently, the models of threat assessment information leakage due to spurious emissions are generic in nature and there are no adequate analytical models to assess the level of spurious emissions at given points inside and outside. No analytical approximation of electro-magnetic fields. In this case, get the numerical evaluation of security is only possible by experimental studies. Based on practical experiments were conducted measuring the levels of spurious emissions at different distances from the radiation source in a wide frequency range. To study the corporate network is made of spline approximation of the experimental data on which to base the analytical expressions for estimating the field attenuation at frequencies investigated by improving the Hata model. The comparison of experimental data and analytical calculations showed the adequacy of the mathematical model. The developed models can analytically evaluate the level of spurious corporate networks and can be used in the design and construction of complex security systems.
