Summary Christian Breitenstrom of SOC service provider uneedsecurity defines the basic homework tasks for adjusting an intrusion detection system, and describes the OT security challenges of SMEs from a practical view point. He proposes a governmental incentive for OT security based on the principle of the Singapore model.
Sound Bites In SMEs, OT folks try to survive workload by sending one mail per day that tells them if anything happened in the OT. Of course, that is not effective from a security point of view.
Without an expert on-prem the IDS typically is configured once and then left running on its own. Of course, this is utterly useless.
A block diagram with a firewall placed somewhere is NOT a worthwhile network plan.
Die main homework tasks for OT security folks are a network plan, an asset inventory and the measurement-and-control pyramid.
In public tenders, the lack of governmental support in OT security leads to prices being pushed down, with the effect of low-quality implementation not even worth that little money.
