Wires and cables that are not connected to IPE and AES may pass through the
rooms intended for processing information with restricted access. The same concerns
metal pipes of water supply and heating systems and other conductive metal structures
referred to as external conductors (EC) [21, 22].
IPE and AES are powered from switchgears and distribution boards, which are
connected to the transformer substation of the urban network using special cables.
All equipment and systems that are powered from the mains must be grounded.
A typical grounding system includes a common ground terminal, a grounding cable,
bus bars, and wires connecting the ground terminal to the equipment.
A number of AES connecting lines, external conductors, as well as the power
supply and grounding lines can go beyond the facility controlled area (CA) (territory,
building, part of the building). Stay of unauthorized persons (visitors, technical staff
who are not employees of the organization), as well as vehicles is strictly forbidden.
The boundary of the controlled area may be the perimeter of the secured area, as
well as the building envelope or the enclosing structures of the protected part of the
building, if it is located in an unsecured area.
A combination of information resources containing restricted access data, equipment and systems for processing information with restricted access, auxiliary equipment and systems, premises or facilities (buildings, structures) for their installation
is a protected computer system (CS) [18, 19].
Protected computer systems must be certified in accordance with the information
security requirements [19].
Premises intended for private negotiations containing information classified as
state secrets are called confidence rooms (CR) and premises intended for confidential
conversations—protected rooms (PR).
Confidence and protected rooms must be certified in accordance with the
information security requirements [19].
Various information systems, which are based on computer equipment (CE), are
widely used for processing information with restricted access. Therefore, computer
systems using CE for information processing are often referred to as “objects of
computer equipment.”
Considered as an object of protection against information leakage through technical channels, an object of CE shall include equipment and systems directly
processing information with restricted access, as well as their connecting lines (the
totality of wires and cables connecting separate IPE and their components).
Thus, CE object generally includes as follows:
• Auxiliary equipment and systems with their corresponding connecting lines;
• External conductors;
• Power supply system;
• Ground system.
A combination of the informative signal source (in this case—CE), interception
equipment and physical medium where the informative signal propagates is called
the technical channel of information leakage (Fig. 1.9).
