MODULE 1
Begin with Physical Consequence and Operating Mode
Translate a safety or reliability concern into observable changes without treating every unfamiliar command as an attack.

Reading estimates use lesson text and an allowance for diagrams. Reflection, exercises and optional linked resources take additional time. These are estimates, not measured completion times.
KNOW WHAT YOU’RE WORKING TOWARD
Security practitioners learning how detection decisions change in operational technology.
Detection reasoning with safety and operational constraints. No interaction with live industrial equipment is required or authorized.
Self-paced reading with explanatory diagrams and linked resources. Reflection and optional resource study take additional time.
Reason about detection in operational technology by starting with physical consequence, operating mode, engineering authority, and the safety limits of evidence and response. The course is written for one reader and develops its ideas through continuous explanation, realistic thought experiments, and explicit distinctions between fact, assessment, and uncertainty.
TRY THE REASONING / FICTIONAL SCENARIO
A passive monitor records a new engineering connection to a controller during a scheduled maintenance window. The observer has no authority to change controller state.
Identify the operating context and verification path. Explain why immediate active testing is not justified by the observation alone.
Establish the asset's operating mode, expected maintenance activity and authorized engineering identities through the responsible operations team. Preserve the passive observation and its limitations. A maintenance window is context rather than blanket approval. Active tests or disconnection can create physical consequences and require the appropriate operating and safety authority.
This example is a reflection exercise, not a scored assessment.
FOLLOW THE LEARNING PATH
MODULE 1
Translate a safety or reliability concern into observable changes without treating every unfamiliar command as an attack.
MODULE 2
Understand what passive network monitoring and engineering-access records can reveal, and where their conclusions stop.
MODULE 3
Choose evidence and interventions that build confidence without assuming production equipment is a safe test target.
