DETECTION NETWORK STEGANOGRAPHY BY COMPARING CHARACTERISTICS OF PROTOCOL WITH THEIR REFERENCE STATE
The problems of leakage of confidential information on a covert channel are revealed. A method for detecting TCP/IP steganography was developed by comparing network traffic with the reference state of the protocol machine, defined by RFC documents and standards. Based on the presented method an architecture of the application that can indicate the potential existence of covert information in network traffic is developed.

The problems of monitoring of security of virtual private networks (VPN) from the network and streaming of computer intelligence and DDoS attacks are considered. On the basis of the analysis of the processes occurring during the monitoring of VPN security it is concluded that the monitoring system should meet the following basic requirements: continuity of monitoring the contrast of VPN in feature space of the Uniform Telecommunication Network of the Russian Federation; continuous monitoring of signs of illegitimate network streaming and computer intelligence; the continuity of the monitoring of signs of DDoS attacks; guaranteed detection of computer network intelligence and DDoS attacks; accurate assessment of damage and ability of the VPN nodes to provide the required services to specified subscribers. The complex algorithm of counteraction to the DDoS attacks and attacks aimed at illegitimate collection of network data is developed.

It is shown that ultra-broadband radio communication systems have good prospects for the organization of object communication, data exchange between spatially distributed information and computing facilities and management of radio engineering complexes. Their technical implementation is based on the use of pulse radio technologies and orthogonal frequency division of channels. The main directions of improvement of ultra-broadband radio communication systems are focused on the development of methods of formation and transmission/reception of signals with high-stable time-frequency parameters as well as their space-time processing in the presence of interference at low power spectral density.

Satellite communication belongs to the industrial and social infrastructure of the information society, so it determines the synergetic character of the effectiveness of its infrastructure projects. To measure the synergetic effect, it is necessary to develop an applied methodology for the comprehensive measurement of the efficiency of investment projects, allowing to estimate many effects and consequences of its implementation, taking into account the relationship with the development of the information society. The article reveals the essence of the proposed integral-expert method (IEM), the comprehensive system of indicators and the model of calculation of efficiency factor of infrastructure projects of satellite communications based on the ratio of the effective and high-cost generalized indicators, taking into account not only economic and social components of the effect but also its positive and negative aspects.
