(EN) SELF-DEFENDING SMART FIELD DEVICE AND ARCHITECTURE
(FR) DISPOSITIF ET ARCHITECTURE DE TERRAIN INTELLIGENTS D'AUTODÉFENSE
Abstract
(EN) An automation system comprises a local threat information server operating within automation plant and a plurality of field devices operating at a control layer of the automation plant. The local threat information server is configured to: receive threat information from one or more external sources, receive plant information from one or more internal sources, set a threat level according to one or more of the threat information and the plant information, and distribute an indication of the threat level to one or more control layer devices. Each respective field device is configured to: receive the indication of the threat level, identify one or more security operations corresponding to the threat level, and execute the one or more security operations.
(FR) L'invention concerne un système d'automatisation qui comprend un serveur d'informations de menace locale fonctionnant dans une installation d'automatisation et une pluralité de dispositifs de terrain fonctionnant au niveau d'une couche de commande de l'installation d'automatisation. Le serveur d'informations de menace locale est configuré pour : recevoir des informations de menace à partir d'une ou plusieurs source(s) externe(s), recevoir des informations d'installation à partir d'une ou plusieurs source(s) interne(s), et régler un niveau de menace selon les informations de menace et/ou les informations d'installation, et distribuer une indication du niveau de menace à un ou plusieurs dispositif(s) de couche de commande. Chaque dispositif de terrain respectif est configuré pour : recevoir l'indication du niveau de menace, identifier une ou plusieurs opération(s) de sécurité correspondant au niveau de menace, exécuter la ou les opération(s) de sécurité.
