conducting checks to detect installed voice recorders;
use of means to stop the operation of installed dictaphones.
Protection against the acoustoelectric channel of information leakage is carried out by:
detection of signals in the electrical network using devices capable of recording signals above 30 kilohertz in the electrical network;
masking the electrical network with noise signals using special devices.
Protection against interception truemoney data package of side electromagnetic radiation and interference (SEMI) of various natures includes the following measures:
PEMIN sources, such as CRT monitors, should be placed as far away from the boundaries of the protected area as possible. This prevents the possibility of obtaining a stable copy of the image at a distance;
buildings, premises, information processing facilities and cable communications must be shielded;
to make it difficult to intercept PEMIN, spatial and linear electromagnetic noise can be used;
local technical systems must not go beyond the protected area;
power supply and grounding circuits located within the protected area must be isolated to prevent the transfer of electromagnetic interference;
In information, power and grounding circuits, special filters should be used to suppress extraneous electromagnetic radiation.
Protection against interception of stray electromagnetic radiation
Protection against the use of grounding as a channel for information leakage
special noise generators should be used on grounding lines;
grounding lines must not have loops, and the resistance of the grounding loop must not exceed 1 Ohm;
grounding can be done using steel pipes driven vertically into the ground to a certain depth;
compacted table salt around grounding pipes can reduce the resistance of the grounding line;
grounding conductors (pipes) must be connected to metal busbars only by welding to ensure a reliable connection;
Earthing via natural earthing conductors (e.g. steel structures) should be prohibited to prevent information leakage through them.
How to achieve multiple growth in traffic and sales from your website?

I have always been concerned about the issue of moving to a fundamentally new level. So that the indicators would grow not by 2 or 3 times, but by several orders of magnitude. From a thousand visits to ten thousand or from ten thousand to a hundred thousand, if we are talking about a website, for example.
And I know that such leaps are always the result of painstaking work in five areas:
Technical condition of the site.
SEO.
Collection of site semantics.
Creating useful content.
Working on conversion.
And at the same time, every manager needs an increase in sales and the number of applications from the site at the moment.
