Protection of technical means against unwanted electromagnetic radiation using TEMPEST filters

ICT tools for information processing can produce damaging radiation - electromagnetic waves that can be captured and analyzed. The processed information can be revealed this way. Electromagnetic waves are disseminated through both, air as well as through data and supply lines.
Act No. 215/2004, Collection of laws on the protection of classified information requires an obligation to ensure protection from leaks of classified information by unwanted electromagnetic radiation (NEV). It follows from § 55 section 1 of the Act that "the technical means can be used only in order to ensure the protection of classified information." The designation TEMPEST is used across the world for the protection against the phenomenon of NEV.
Protecting information leakage through the NEV can be ensured in several ways, depending on the specific conditions of work. It takes into account the degree of secrecy, protected areas themselves, as well as technical means.
Suppression filters with high attenuation (TEMPEST filters) are used to eliminate NEV through power line (230V)
The actual operation of technical equipment is subject to a valid certificate NBU (National Security Office), which contains a reference to the installation record in its annex. Installation record describes in detail the configuration of the technical means and method of its installation in a particular area, including compliance with the minimum distances required to ensure the requested degree of protection against NEV. The obligation to use TEMPEST filter is usually referred to in the installation record.
Another obligation of the operator is that the technical equipment must be, prior to approval to operate, installed in accordance with the installation record, and this can only be used in accordance with the approved installation record.
