The security of industrial IoT networks and fieldbuses is one of the “hot topics” in the community, not least because of the new legal requirements of the EU Cyber Resilience Act (CRA), the new initiative for network and information security (NIS 2.0), the Europe-wide EU RCE (Resilience of Critical Entities) directive, the planned KRITIS umbrella law and the IT Security Act 3.0 (SiG 3.0). Conventional IT and IoT networks have been protected for many years with intrusion detection systems (IDS) and intrusion prevention systems (IPS), among others. For some years now, complete security information and event management (SIEM) systems that comprehensively combine as many suitable technologies as possible (such as intrusion detection and prevention, asset management, log analysis) have also been in use. Bremen-based Decoit GmbH has been developing such SIEM systems for the IT sector for years. The ivESK at Offenburg University of Applied Sciences has also been researching and developing the protection of fieldbus and industrial IoT systems for a long time and in many projects. This seemed a very good prerequisite for bringing these complementary skills together in a joint project. The ZIM project KISTE is now designing and developing an “AI-supported SIEM system for highly reliable industrial IoT networks and fieldbuses”. The project was launched on August 30 with a kick-off project at the university. More information at www.kiste-project.info. This project is funded by the Federal Ministry for Economic Affairs and Climate Protection (BMWK) on the basis of a decision by the German Bundestag.
