Control Statement
Findings raised by architectural review shall be dispositioned as remediated, accepted with justification, or transferred, within a defined period.
Purpose. To ensure every finding reaches a decision, so that the open set reflects work in progress rather than accumulated neglect.
Discussion
Acceptance is where this control is defeated. A finding accepted permanently, by someone without the authority to accept it, disappears from view while the risk remains — and a program with a large accepted set can report a small open set indefinitely. Two requirements close that: acceptance must be by a person whose risk authority covers the exposure, and it must expire, forcing periodic re-decision rather than one-time disposal.
Goals and Metrics
A metric that cannot come out badly is not a metric. Each of these is capable of reporting that the control is not working.
- Percentage of findings dispositioned within the defined period
- Age of the oldest undispositioned finding
- Number of accepted findings carrying a written justification and a named accepting authority
Accountability
Exactly one role is accountable, and every other role carries at least Informed — no control in the published catalog leaves a role with zero relationship to it. That is a stated property of how these were authored, not a coincidence, and not a claim that every role's work is worth equal attention here.

Activities
- L2Record every finding with its source and date.
- L2Disposition each as remediated, accepted with justification, or transferred.
- L2Define the period within which disposition must occur.
- L3Require acceptance to be made by a person whose risk authority covers the exposure, recorded by name.
- L3Give every acceptance an expiry, after which it returns for re-decision rather than persisting.
- L3Record for transferred findings who received them and their acknowledgment.
- L3Escalate findings exceeding the disposition period rather than ageing them.
- L4Trend the accepted set alongside the open set, since a shrinking open set and a growing accepted set is not improvement.
- L4Measure re-decision outcomes on expiry — acceptances renewed without change indicate risk being deferred rather than managed.
- L5Feed recurring finding types back into the control that generates them, since a finding class that keeps recurring is a design problem rather than a remediation backlog.
Measurement
Percentage of findings dispositioned within the defined period.
Ratio of accepted to remediated dispositions, trended.
Evidence and Assessment
Findings register with disposition, dates, named acceptors and expiries; transfer acknowledgments.
Examine open findings against the defined period; test the justification recorded for accepted risks; test whether acceptors held authority covering the exposure.

Where This Control Is Used
Derived, in every case, from the declaration at the other end: the forms whose techniques name this control, the artifacts whose producing and consuming controls include it, the layers whose control lists name it, and the roles its own accountability chart puts to work. Nothing here is authored on this page, so the sheet cannot claim an edge the other end does not.
Forms of Maneuver It Assesses

Terrain It Is Named On
- TXCross-CuttingFindings disposition, which is what stops governance maturity from being a documentation exercise.
Artifacts It Stands On
- producesFindings disposition recordEvery finding with an outcome: remediate with an owner and a date, accept with a named accepter and an expiry, or transfer with the party named. “Under review” is not a disposition.
- consumesTemporal advantage thresholdThe number the cycle will be judged against: defender decision loop versus adversary dwell, stated with units before the cycle runs.
- consumesCyber Terrain OverlayThe positional map of the estate: every element with a defensive layer, a defensive weight, a named accountable owner and its adjacencies. Not an asset inventory — an inventory enumerates, an overlay positions.
