Industrial Automatic Control Systems and Controllers Annotation << Back Covert Channels Problem in Industrial Control Systems(ICS) and Networks Bezukladnikov I.I., Kon E.L. Аннотация: This article addresses the problem of covert channels threat in the Industrial Control systems and networks. Given analysis shows the urgency of this threat as one of the most dangerous for this class of systems, and reveals basic problems hindering the implementation of a systematic approach to the analysis of covert channels in the industrial control systems(ICS). Necessary conditions for the existence of a covert channel in the ICS are formulated. A classification of covert channels, which includes several new, previously unknown species is shown. Keywords: Covert channels, covert channels classification, unauthorized access, information security, SCADA, Industrial control systems. E-mail:corrector@at.pstu.ru. Pp. 61-64.
