Episode 35 — Define Scope and Assumptions
Clear scoping defines what will be tested, how, and under which constraints—preventing confusion that delays authorization. This episode explains how to delineate in-scope systems, components, environments, and data flows, linking each to authorization boundaries, interconnections, and inherited services. We address assumptions such as stable network configurations, operational baselines, access provisioning windows, and agreed test accounts. You will learn to record these in the Security Assessment Plan so that both the 3PAO and provider share identical expectations. Scope discipline ensures testing reflects reality, results remain repeatable, and findings are relevant to the authorized environment.
We then highlight common scoping mistakes—omitting auxiliary environments like staging that mirror production, ignoring management planes, or misidentifying external dependencies as out-of-scope. Examples show how to mitigate them by verifying inventory completeness and reconciling diagrams with scan targets. Document any restrictions, such as avoidance of load-testing production databases, and justify them with risk rationale and compensating evidence. Update scope definitions if architecture or configurations change during testing and notify reviewers promptly. Well-defined scope and documented assumptions create a foundation for objective evidence, meaningful findings, and trust in assessment integrity.
