Episode 67 — Turn Telemetry Into Intelligence: Logs, Sessions, and Anomalies That Matter
This episode explains how to turn telemetry into usable intelligence by focusing on signals that matter in OT, where too much noise can be as dangerous as too little visibility. You’ll learn how to think about logs, sessions, and network observations as evidence streams, then apply simple analytic questions like “what is normal here,” “what changed,” and “what could that change enable” to move from data to decisions. We cover the types of telemetry that often provide the most leverage, including remote access session records, authentication events, firewall and jump host logs, engineering workstation activity, and network anomalies in industrial protocols that should normally be predictable. The episode emphasizes that anomalies must be interpreted with operational context, such as maintenance windows, commissioning activities, or process upsets, so you avoid false alarms that erode trust with operations. You’ll also learn best practices for baselining, time synchronization, and correlation, and how to choose safe investigative steps that preserve evidence and reduce risk without touching control logic or disrupting process traffic unnecessarily.
