The paper provides an analysis of the principles of the multichannel protection system. The analysis showed that in order to solve the problem of ensuring secure communication with an external resource through public networks, it is advisable to use a multi-channel system with different channel capacities, while the main channel and spare channels that are connected to work when the main channel cannot handle all incoming applications with probability of 0.95. This model takes into account that the channels are filled hierarchically, and are freed up as the applications are processed.

The article provides an analysis of the proposed system for protecting confidential information of the organization. The rationale for the need for comprehensive protection is given, since the unidirectional system is not effective enough, leads to early failures and the loss of important confidential information, as well as an adaptive monitoring unit
