Complex for assessing the effectiveness of speech information protection from leakage via acoustic and acoustoelectric channels Kolibri

Purpose:

• measuring the parameters of acoustic, vibroacoustic and low-frequency electrical signals;

• identifying technical leakage channels (TLC) of speech information and determining the technical protection indicators of speech information (discussed in designated rooms of categories 1, 2 and 3) from leakage via acoustic and vibroacoustic channels (AVAC), as well as due to acoustic-electrical transformations (AET) in elements of auxiliary technical means and systems (ATSS) in accordance with the current organizational, administrative and regulatory documents of the FSTEC of Russia.

Scope:

• measuring noise and vibration levels;

• assessing the parameters of acoustic, vibration and low-power LF electrical signals in order to identify TLC of speech information;

• assessing the effectiveness of speech information protection from leakage via AVAC, as well as due to AET (including when using sound amplification equipment);

• assessment of the effectiveness of the applied means of protecting speech information from leakage via the above-mentioned technical channels.

The device complies with the requirements established in the documents "Collection of regulatory and methodological documents on counteracting acoustic speech intelligence" (State Technical Commission of Russia, 2000), "Methodology for assessing the effectiveness of protecting speech information from leakage due to acoustoelectric transformations in technical means and systems" (FSTEC of Russia, 2018).
