Trust continues after approval

Monitor relevant changes that could affect a decision’s validity.

Approval has a time dimension

A trust decision reflects an asset, evidence, and criteria at a particular time. Software updates, configuration changes, expired evidence, or new operating conditions can affect that basis. Continuing to display an earlier approval without examining relevant changes can leave users relying on an outdated conclusion.

Define what should trigger review

The QILAHK approach treats continuity as part of governance. A Trust Profile should identify the conditions supporting the decision, the evidence that needs refreshing, and the changes that require reassessment. Monitoring then has a defined purpose: detect changes within its agreed coverage and connect them to a review process. Collection intervals, available integrations, and response responsibilities belong in the scope of the engagement.

An endpoint example

Suppose a reviewed device later changes its boot configuration. When the agreed monitoring process detects that change, the record should identify the affected asset and decision, preserve the new evidence, and route the issue for review. The authority can determine whether the decision remains valid or requires a status change. Detecting a change does not itself prove compromise, and monitoring cannot be assumed to observe every event.

The business difference

Continuity helps organizations keep assurance aligned with operating reality. It gives reviewers a reason to ask when a result was last checked and what changed since then. The value comes from agreed coverage, timely evidence, and accountable action—not from treating an approval as permanent.
