TOOL FOR THE CENTRALISED SUPERVISION AND/OR HYPERVISION OF A SET OF SYSTEMS HAVING DIFFERENT SECURITY LEVELS

摘要

The present invention relates to a tool for the supervision and/or hypervision of a set of systems having different security levels, the systems (101, 102) transmitting messages, wherein the tool comprises a display system (135) and is characterised in that it comprises, for each supervised network, at least one gateway (115, 125) for converting the messages into image data, said gateways transmitting said image data via a unidirectional video link (51, 152) to the display system, at least one of the supervised networks having a security level higher than the area in which the display system is provided. The invention can particularly be used for the centralised monitoring of several information systems when said systems are subjected to different security constraints.
