organizations:DetachPolicyOn its own, organizations:DetachPolicy can detach an SCP guardrail from an account or OU. On a wide resource scope that alone reaches blinded detection or removed guardrails.
Why it is dangerous
A principal can call organizations:DetachPolicy to detach an SCP guardrail from an account or OU, removing an org-wide Deny the rest of the model relies on.
In MITRE ATT&CK terms this maps to T1562.001, Impair Defenses: Disable or Modify Tools, under the defense evasion tactic. AWS records it in CloudTrail as DetachPolicy. The call shows up in CloudTrail but blends into normal administration, so it needs a rule to stand out.
Detection
DetachPolicyPrerequisites
organizations:DetachPolicy from the management or a delegated-admin account.
Tactic
Defense Evasion
A control that would remove it: Restrict organizations:DetachPolicy to a break-glass management-account role; alarm on SCP detachment.
Whether to apply it depends on how the permission is used in your environment, so it is a business decision rather than an automatic fix. The same permission can be load-bearing in one account and pure risk in another.
