Detection Validation Evidence

What evidence should demonstrate that a security detection has been validated?

Published 2026-08-17Reviewed 2026-08-17
Direct answer

Retain the detection objective and version, telemetry prerequisites, test case, expected result, actual result, test date, reviewer, benign or edge-case tests, unresolved limitations and any tuning that followed. Validation evidence should be repeatable after material changes.

Claim boundary

Validation evidence supports confidence in a defined test case; it does not prove universal detection, zero false negatives or security effectiveness outside the tested conditions.
