One of the key directions in the development of modern society is the formation of an integrated information space based on the latest information technologies. The widespread use of information technologies and infocommunication networks for the transmission, reception, processing and storage of information in various fields of activity, on the one hand, contributes to an increase in the efficiency of this activity, and on the other hand, it causes the emergence of threats of information leakage through technical channels, which are understood as the uncontrolled dissemination of information signal from its source through the physical environment to a technical means that intercepts information. In the list of threats, an important place is occupied by threats of information leakage through channels of compromising electromagnetic emanations, as well as a result of interference of information signals in power lines of technical means of information processing, connecting lines of auxiliary technical means and systems, ground circuits and extraneous conductors. To protect information from its leakage due to compromising electromagnetic emanations through communications connecting the system blocks of computing facilities with peripheral devices, it is important to analyze the formation of these signals and emissions. The article presents the results of the study of compromising electromagnetic emanations of the USB 2.0 interface, carried out to solve the problems of assessing the security of information at the objects of information activity. The processes of formation of technical channels of information leakage by compromising electromagnetic emanations at use of the USB-interface in structure of control system of information and communication networks are considered. The images of the signal levels of the compromising electromagnetic emanations of the USB 2.0 interface obtained with the spectrum analyzer ROHDE & SCHWARZ FSW 13 (Signal & Spectrum Analyzer) using the R & S Active Dipole Antenna HE527 are shown. As a result of the analysis of the form and spectrum of signals in the USB cable (test mode is off, test mode is on) it is established that in the USB interface there is a constant transmission of service packets to support the interface. When the test mode is turned on, additional pulse sequences appear on the spectrogram. The frequency of the first harmonic for the USB 2.0 interface is in the region of 240 MHz.
