FIELD: information protection.
SUBSTANCE: invention relates to the field of protection of limited-distribution information, namely, protection of information from leakage via channels of side electromagnetic emission and pickup, and can be used to automate monitoring and control of the security of information processed by computer equipment. To realise the technical result, a method is proposed, consisting in continuous (or with a predetermined frequency) automated monitoring of the operability of the technical information protection means used on the IO, electromagnetic emission of the technical means of the IO, technical monitoring means and, if necessary, formation of masking noise signals of the required power by a backup subsystem for technical information protection in the required frequency bands on predetermined sections of the IO.
EFFECT: ensured continuous safe work with limited-distribution information at informatisation objects (IO).
