Applications of IT Equipment Protective Solutions Against Electromagnetic Compromising Emanations

Attenuation of unwanted emissions levels is one of the basic undertakings targeted to minimize the threat from electromagnetic infiltration of IT equipment. The electromagnetic infiltration bases on the disturbances generated by IT equipment existing as the emission of radiated disturbances as well as the emission of conducted disturbances that are potential radiated compromising emanations as well as conducted compromising emanations. In the case of the radiated compromising emanation, protections in the form of shielding enclosures characterized by an adequate value of shielding effectiveness should be applied. In the case of the conducted compromising emanation, protections in the power supplying wires in the form of power supply filters characterized by the suitable high attenuation should be applied. Example design of protective solutions for IT equipment in the form of a chamber, shielding cabinet as well as enclosures integrated with protected IT were discussed in the article.
