Who is accountable for removing excessive cloud permissions once a review finds them?

Why This Matters for Security Teams

Once an access review finds excessive cloud permissions, the real risk is not the finding itself but the delay between detection and removal. Cloud entitlements often sit across IAM roles, service accounts, workload identities, and delegated admin paths, so accountability can blur unless the owner is named in advance. That is why identity governance must connect findings to a decision-maker, not just a report. Guidance from the OWASP Non-Human Identity Top 10 reinforces the need to govern non-human access as a lifecycle problem, not a one-time review.

NHIMG research shows the operational gap clearly: in The 2024 Non-Human Identity Security Report, only 19.6% of security professionals expressed strong confidence in securely managing non-human workload identities, while 88.5% said their practices lagged human IAM. That matters because cloud permissions rarely fail in a neat audit trail. They fail when nobody feels authorized to act, or when remediation is left for a later cleanup cycle that never comes. In practice, many security teams encounter lingering over-privilege only after it has already been used, rather than through intentional revocation.

How It Works in Practice

Accountability should follow the entitlement owner that can actually approve removal and absorb the business impact. In most cloud environments, that means the application owner, platform owner, data owner, or business owner tied to the workload, with security or IAM operating the workflow and preserving evidence. The control should not stop at identification. It should open a tracked remediation task, define a due date, and verify the permission was removed or reduced. NIST control language in NIST SP 800-53 Rev 5 Security and Privacy Controls supports this kind of access enforcement and accountability mapping.

Good practice usually includes:

• Mapping every cloud role, policy, and service principal to a named owner before the review starts.
• Routing review findings to that owner, not to a generic mailbox or shared queue.
• Recording the remediation decision, including accepted risk, compensating control, or removal.
• Using IGA or ticketing to confirm closure, then rechecking live permissions in cloud control planes.

This is especially important for non-human identities because excessive access can persist in automation, CI/CD, and infrastructure-as-code pipelines long after a human reviewer signs off. NHIMG’s Ultimate Guide to NHIs, Key Challenges and Risks highlights how unmanaged NHI sprawl makes ownership harder to trace, which is why remediation ownership must be explicit. These controls tend to break down in multi-cloud environments with shared platform teams and inherited IAM roles because the permission source and the business owner are not always the same person.

Common Variations and Edge Cases

Tighter ownership rules often increase remediation overhead, requiring organisations to balance faster removal against avoiding disruption to production services. There is no universal standard for this yet, but current guidance suggests using the lowest-friction owner who can safely approve change and documenting escalation paths when that owner is unavailable. Where permissions support shared infrastructure, the platform team may execute the removal while the service owner approves the business impact. Where access is tied to regulated data, the data owner may need final sign-off.

Edge cases usually appear when entitlement ownership is stale, when multiple teams share a cloud landing zone, or when an application has no maintained owner at all. In those cases, the review outcome should not be treated as closed simply because the finding was acknowledged. It should move into exception handling with a time-bound remediation plan. For cloud privilege issues involving credentials, keys, or tokens, the relevant question is often whether the entitlement can be removed immediately or whether a short-lived replacement is needed first. NHIMG has documented how over-permissioned cloud paths can escalate quickly in incidents such as the Azure Key Vault privilege escalation exposure and the Microsoft SAS Key Breach. The practical rule is simple: if nobody owns the entitlement, the risk still belongs to the organisation, but the remediation cannot be left ownerless.
