OT SECURITY MADE SIMPLE

This article examines significant real-world incidents, the actual evolution of OT malware, the TTPs (tactics, techniques and procedures) of modern threat actors, and key findings from the situation reports published by the BSI and Dragos.

When temperatures rise in the summer, millions of people head to the water. Whether it’s relaxing at the lake, visiting public pools, or enjoying a cold, refreshing drink straight from the tap. The availability of clean water is something wetake for granted as part of our quality of life. This makes what happens behind the scenes all the more critical: securing our water supply and wastewater management systems.

In the modern industrial landscape, operational technology (OT) is no longer isolated. While connectivity drives efficiency, it also introduces unprecedented risks. The publication of the German Technical Rule for Operational Safety (TRBS) 1115 Part 1 explicitly addresses this reality, setting stringent guidelines for the cybersecurity of safety-relevant measurement, control, and regulation (MSR) systems.
