Episode 31 — Detect identity anomalies by understanding normal authentication behaviors
This episode teaches you how to define “normal” authentication behavior so anomalies become measurable signals instead of vague suspicion, a skill the GPCS exam tests when it asks you to choose the best detection or investigation step. You’ll clarify baselines such as typical login times, source networks, device patterns, MFA usage, session durations, and the common sequence of sign-in events that follow successful authentication. We’ll connect authentication telemetry to authorization outcomes so you can distinguish a harmless user mistake from adversary behavior like password spraying, impossible travel, token replay, or abnormal session creation. A scenario follows a privileged user account that begins authenticating from an unusual region and rapidly enumerates cloud services, and you’ll practice identifying which events matter first, what supporting logs to pivot to, and how to avoid false positives caused by legitimate travel or automation.
