847 alarms before the operator took off his jacket. 95% were known noise. A real chiller fault sat buried for 112 minutes.

We ran ISA-18.2 rationalization: 90%+ alarm reduction, response time from 180s to 45s, zero missed critical alarms in 6 months.

Stop blaming operators. Fix the system.

Through the upcoming #PapersInSystems discussion I discovered Nancy G. Leveson and her work on #SafetyEngineering and software safety through a systemic perspective

It is fascinating and feels very applicable to #cybersecurity

In their approach STAMP
(System-Theoretic Accident Model and Processes) safety is treated as a dynamic control problem rather than a failure prevention problem and especially takes emergent properties into account. (Emergent properties, are properties that are not in the summation of the individual components but "emerge” when the components interact)

There are a lot of touchpoints with security #ThreatModelling
