Who should be accountable for fixing cloud identity and permission gaps found by CNAPP?

Why This Matters for Security Teams

CNAPP can surface cloud identity and permission gaps, but it does not own the business risk behind those findings. That accountability belongs with the cloud security function that sets guardrails and the application or platform owners who can confirm whether access is still needed. This split matters because identity findings are only useful when someone has authority to remove excess privilege, rotate access, or accept the residual risk.

The scale of the problem is not theoretical. NHI Management Group notes that only 5.7% of organisations have full visibility into their service accounts in the Ultimate Guide to NHIs, and excessive privileges remain widespread across cloud estates. When teams treat CNAPP as the owner instead of the detector, remediation stalls. The same pattern shows up in breach analysis and identity research, including the 52 NHI Breaches Analysis and the OWASP Non-Human Identity Top 10, both of which stress that visibility without ownership does not reduce exposure.

In practice, many security teams discover that “known” permission gaps are still present weeks later because no named owner was assigned when the alert first landed.

How It Works in Practice

The cleanest operating model is a three-step workflow: detect, validate, remediate. CNAPP identifies over-permissioned roles, stale secrets, or cross-account access paths; cloud security operations triages the issue and assigns it to the resource owner; the owner confirms whether the access is required for the application, pipeline, or platform to function. If the access is unnecessary, security or platform engineering removes it. If it is required, the owner should narrow scope, shorten credential lifetime, or document an exception with expiry.

This is where cloud identity governance overlaps with broader NHI management. The Ultimate Guide to NHIs highlights how often organisations store secrets outside approved vaults and keep them valid long after notification. That is why a CNAPP finding should trigger a remediation owner, not just a ticket. The control objective is not “close the alert”; it is to prove that the identity is still justified, least privileged, and revocable. NIST’s NIST SP 800-53 Rev 5 Security and Privacy Controls supports this model through accountability, least privilege, and access review expectations, while the OWASP NHI guidance gives practitioners a practical lens for service account governance.

• Cloud security operations owns the policy, triage, and escalation path.
• Application and platform owners validate business necessity for each permission.
• IAM or platform engineering implements the change in the cloud control plane.
• Risk or compliance teams track exceptions, deadlines, and evidence.

Best practice is to route every unresolved finding to a named owner with a due date and a clear remediation outcome, because orphaned findings become permanent risk. These controls tend to break down in multi-account environments with shared service principals and outsourced platform teams because no single group has both context and authority.

Common Variations and Edge Cases

Tighter ownership often increases operational overhead, requiring organisations to balance faster remediation against the coordination cost of multiple teams. That tradeoff is real, especially in large cloud estates where platform teams, app teams, and security operations all touch the same identities.

There is no universal standard for this yet, but current guidance suggests a few exceptions. In managed service or third-party cloud models, the vendor may implement the fix while the customer still retains accountability for approving the change and validating the residual risk. In highly automated environments, platform engineering may own the technical rollback, while cloud security defines the policy and evidence requirements. For ephemeral workloads, the right answer may be to delete and recreate access rather than “fix” a long-lived permission set.

The key edge case is shared ownership without decision rights. If a team can see the CNAPP finding but cannot change the identity, the finding must escalate to whoever can. Otherwise, the alert becomes a compliance artefact instead of a security control. This is especially important when service accounts, API keys, or CI/CD credentials are reused across applications, because the impact of one excessive permission often extends far beyond the original ticket. Research from NHI Management Group shows how often these identities remain over-privileged, and the Top 10 NHI Issues page is a useful reference for prioritising those recurring failure modes.
