Episode 42 — Scope incidents rapidly using hypotheses, timelines, and high-value evidence
This episode teaches rapid scoping as a structured method rather than a guessing game, which GSOM tests because effective scoping determines whether you contain the right systems and avoid wasting hours on low-value data. You will define a hypothesis as a testable statement about attacker activity, then learn how to build and refine it using a timeline anchored to high-confidence events like authentication records, endpoint execution traces, and known changes to accounts or configurations. We will explain what “high-value evidence” looks like in common scenarios, including privileged identity use, lateral movement indicators, persistence attempts, and data access events that imply impact, and how to prioritize collection when time is limited. Troubleshooting considerations include conflicting signals between tools, partial visibility across environments, and noisy baseline behavior, with best practices for narrowing scope by validating the earliest known event, identifying the blast radius, and documenting what remains unknown.
