This article reviews the one of the most dangerous types of non-traditional security threats of industrial systems-covert channels. Developed by the authors is given an open classification of covert channels on the basis of the form of under-utilization of an information resource, which includes, along with well-known, several new classes of covert channels. For a part of such classes in the article are examples of possible covert channels, which operate on the basis of industrial fieldbus-based network Neuron Chip.
