Tool for the Centralized Supervision and/or Hypervision of a Set of Systems Having Different Security Levels

摘要

A tool for the supervision and/or hypervision of a set of systems of different security levels, the systems transmitting messages, includes a display system, and further includes, for each supervised network, at least one gateway for converting the messages to image data, said gateways transmitting said image data via a one-way video link to the display system, at least one of the supervised networks being of a higher security level than the area in which the display system is placed. The invention applies notably to the centralized supervision of several information systems when said systems are subjected to different security constraints.
