Overview

This guide explains account enumeration prevention. Start by identifying the data, workflows, and users affected, then select controls that can be tested and maintained over time.

Practical checklist

Document scope and owners; identify trust boundaries and dependencies; use approved test accounts and synthetic data; apply secure defaults; log security-relevant events; and assign corrective actions with deadlines.

Common mistakes and boundaries

Do not infer permission from public access, test unrelated systems, collect unnecessary personal data, or treat one automated result as proof. Stop if testing causes unexpected impact or the scope is unclear.

Verification

Define expected behavior, test both permitted and denied actions in an authorized environment, record limitations, and add regression tests so future changes preserve the control.
