Episode 82 — Apply a Collection Management Framework: What to Collect, How Often, and Why

 This episode teaches how to apply a collection management framework so OT security data collection is purposeful, sustainable, and aligned to operational constraints rather than being an endless hunt for “more logs.” You’ll learn how to define collection requirements by starting with decisions you need to support, such as detecting abnormal remote access, validating change control, confirming asset presence, and proving control operation for compliance. We discuss collection sources across OT and supporting IT systems, including jump hosts, authentication platforms, firewalls, engineering workstations, passive network sensors, physical access controls, and process-support systems like historians, while emphasizing that each source must be evaluated for safety impact and data reliability. Frequency is framed as a risk and practicality decision, balancing near-real-time needs for high-risk pathways against periodic validation for slower-moving controls like access reviews and baseline checks. You’ll also learn how to document collection plans with scope, retention, ownership, quality checks, and feedback loops so the program improves over time instead of accumulating unusable data.
