Technical means of information protection

Technical methods of protecting information occupyone of the most important places in the implementation of security policy in any organization or significant facility. These tools are used to search for the theft of information technology, which sometimes happens to be installed on site, to isolate premises during negotiation or any important meetings in order to protect communications and equipment used for information processing.

Technical means of information protection: the choice of equipment

To issues related to the choice of equipment,intended to provide protection for your organization, it is necessary to approach with special attention. You should consider when choosing generators of radio interference, noise control devices, telephone line protection devices, and other equipment, a sufficient number of factors that are determining: their strengths and weaknesses, mutual influence on each other, and a host of other factors. Using special materials, you can not only familiarize yourself with the spectrum of action of such equipment, but also decide on the final choice.

Technical means of information protection: premises

To protect the premises,different types of acoustic and vibro-acoustic noise. Their main purpose is to protect speech information that can circulate indoors, from listening with the use of different types of stethoscopes, acoustic microphones, infrared and laser systems of information theft. These systems work by creating a masking of the speech spectrum, through broadband unfiltered acoustic noise in ventilation, heating, water supply systems, as well as in enclosing structures.

Technical means of information protection: telephone lines

Telephone lines are considered to be the mostprobable ways of information leakage. Most devices for active protection of telephone lines are designed to neutralize the listening and recording equipment, which is connected between the station and the subscriber unit. The protection is realized by generating high frequency and low frequency interference to the phone line, regulating the electric current consumption in the line during the conversation, which causes a decrease in the quality of the signal at the input of the listening equipment, and also blocks the acoustic start of the sound recording equipment. If radio transmitting devices are used, there is also a shift in the channel frequency or blurring of the transmission spectrum.

Technical means of information protection: electronic systems

Modern business can not exist withoutuse of large amounts of information that involves the use of electronic processing systems that generate spurious electromagnetic radiation. With the help of specialized technical means, it is quite possible to intercept them outside the control zone, and then completely restore the information. In addition to such emissions near operating electronic devices, there is always a quasi-static information electric and magnetic fields that rapidly decrease with distance, however, require pickup on circuits that are located close enough. Such fields are significant at frequencies from tens of kilograms to tens of megahertz. In this case, the interception of information becomes possible when the receiving equipment is directly connected to these communications outside the protected area. To exclude leakage of information through such channels, noise generators are used that are engaged in the production of active masking of spurious electromagnetic radiation.

As you can see, at the moment there are quite effective ways and means of protecting information that can be used in the conditions of modern companies.
