To ensure the operation of the sensors, it is preferable to use the computing capabilities of the operating system of a personal computer, for example, Widows, Linux, MS-DOS or MSVS.

To increase the safety of a personal computer, physical models are used that imitate the design of a set of watchdog sensors.

To increase the safety of a personal computer, physical models of office equipment are used, equipped with a set of watchdog sensors.

The proposed invention is illustrated by drawings (Fig.1-Fig.3):

The sensors can be placed (Figure 2) on the system unit of a personal computer in various designs, for example, installation in slots

expansion of a computer system, connection to external ports of a personal computer.

When placing the sensor in a 3.5 or 5.25 inch slot, or in a PCSMA slot, it is connected to the means of computer and organizational equipment using the USB, FireWare, Lan interfaces.

When placing the sensor in the rear panel of a personal computer, for example, a PCI card, protection is provided against unauthorized approaching the back of the system unit of a personal computer. The element base of the PCI board ensures the matching of sensors with the command and address codes of a personal computer. With the external performance of the sensors, it is connected to computing and organizational equipment via the LPT, USB, FireWare, Lan interfaces, as well as using ADSLx or Dial-Up modems.

Sensors can be placed in the cavity of the system unit together with a backup power source, a Wi-Fi, WiMAX, Zebedee, Bluetooth standard transceiver. A detector for reading RF-ID access cards can be connected to the front panel of the system unit. Sensors can be combined with a passive fire extinguishing system or a protective information destruction system. Sensors may be able to communicate over the air with remote units. When sensors are used, it is preferable to use the computing capabilities of the operating system of a personal computer, for example. Widows, Linux, MS-DOS or MSVS.

To increase the degree of protection of the system, the system unit of a personal computer is supplemented with dummies of sensors disorienting a possible attacker. Sensors can be disguised as faceplates on 3.5 or 5.25 inch drives or optical drive drives. For example, under the optical disk drive, the volume wheel will be a switch of sensitivity and detection range, the button, the opening will be a power button or a button pressed at the time of entering the access code from the remote control

authentication cards or keyboards, the LED operation indicator will be an infrared transceiver for coordinated operation with other sensors.

To control a set of sensors, a sensor control panel 10 (radio or infrared control) is used. The remote control 10 must provide scheduled control, with a ban on management at certain hours and days of the week, network management (including over the telephone line) and configuration.

When assembling the system unit of a personal computer, for example, when reconfiguring it, the sensors are installed in the free cavity of the system unit of the personal computer, the mounting points of the sensor correspond to the standard for mounting optical drives in AT, ATX, VTX and server enclosures. The connector of the power supply unit of the PC case is connected to the response socket of the sensor power. The interface cable is laid inside the case of the personal computer to the location of the USB or FireWare connector on the motherboard and then is connected to it. The response part of the interface cable is connected to the connector on the printed circuit board in the design of the sensor unit inside the computer.

The system for protecting the premises and personal computer from unauthorized access and external influences works as follows.

The operator of the personal computer fixes the location of the personal computer in the room, for example, the direction of his face to the door or window and adjusts the sensitivity of the sensors (1-8), the delay time, etc.

The algorithm of the sensors in terms of level and duration of the signal in the mode of cutting off noise and false alarms is shown in Figure 3.

A personal computer or personal computer system continuously, discretely, or sequentially interrogates sensors (1-8).

The received data is processed in a form compatible with data transfer via the interface bus to a personal computer.

The signals received by the sensors (1-8) are divided into discrete levels of states, with a certain sensitivity threshold for each of the states.

Sensor signal processing is performed at a comparator level with programmable delay times. Thus, false alarms arising from unintended impulse stimuli (pops of pressure, flashes of light, electromagnetic interference and other factors causing false alarms of the security system) are eliminated.

When determining a signal (the duration of the required signal t) that does not exceed the set sensitivity threshold during the response time (t <t _cp ), the signal is ignored by the system and does not produce an alarm.

For long-term and reliable operation of the system by means of a protected personal computer, statistical processing, accumulation and adoption of alternative control decisions with respect to frequent or periodically repeating signals that do not lead to the operation of the system are provided.

When determining a signal (time t) exceeding the sensitivity threshold during a time of a greater sensitivity threshold during the response time (t> t _cp ), the signal is processed by the processing and decision-making system and issues an alarm signal to the safety control line. Further actions of the protection system and personnel are regulated by emergency software installed on a personal computer.

Actions to receive an alarm may include:

monitoring changes in the values of sensor signals;

software shutdown;

increase system security;

disable and lock the system unit;

destruction of system unit data;

substitution and provision of false access to data;

alert security services.

The proposed technical solution can be used in ground-based complexes of automated control of spacecraft to protect around-the-clock means of computing and organizational equipment, for independent use of specialists at automated workstations, as well as to ensure the safety of personal computers (laptops, communicators, PDAs) outside the protected premises. Thus, in practical implementation it will be ensured: ease of management and high secrecy of the system for protecting premises and information resources;

simplicity of visual management, configuration and administration of security systems, both one and a set of personal computers;

remote control of the security system with the ability to use remote controls to enter codes for turning off and changing modes, as well as the ability to use smart access cards made in the form of memory sticks and other means of personal and group authentication;

high in comparison with the known solutions, the secrecy of the system for protecting the room and personal computer from unauthorized access and external influences.
