Episode 24 — Turn organizational use cases into specific data source requirements fast

This episode explains how to translate security use cases into concrete data requirements, which is a high-yield GSOM skill because the exam often tests whether you can identify what evidence is needed to detect a behavior and investigate it quickly. You will define a use case as a statement of what you want to catch, why it matters, and what observable signals prove it, then convert that into specific log sources, event types, and fields that must be present and searchable. We will walk through examples such as suspicious privileged logins, lateral movement patterns, and data exfiltration concerns, showing how each one demands identity events, endpoint process data, network connections, and sometimes cloud audit logs to confirm scope and intent. Troubleshooting considerations include vague use cases that cannot be measured, missing fields that break correlation, and “data exists but is unusable” problems caused by inconsistent formats or no retention, along with best practices for writing requirements that engineers can implement and analysts can validate.
