Ownership should sit with identity and cloud security together, because entitlement risk spans access design, operational enforcement, and ongoing review. IAM defines what should be allowed, PAM controls how elevated access is used, and cloud teams understand the workload context. If those functions are split without a shared workflow, privilege creep usually wins.
Why Cloud Entitlement Risk Needs Shared Ownership
cloud entitlement risk sits at the intersection of identity design, privileged access enforcement, and workload context, so no single team can see the full blast radius on its own. PAM governs how elevated access is approved and used, while CIEM surfaces excessive permissions across cloud services. When those signals are split, a team can approve access that looks valid in isolation but is excessive in practice. That is why the ownership question is less about a tool category and more about a shared control model, aligned to the NIST Cybersecurity Framework 2.0 and NHI lessons documented in the Top 10 NHI Issues.
For identity and cloud teams, the key mistake is treating entitlement review as a periodic cleanup exercise instead of an operating model. Cloud entitlements change with deployments, service integrations, and temporary elevation requests, so stale ownership quickly becomes a control failure. The right owner is usually a joint function with identity accountable for policy and cloud security accountable for platform reality. In practice, many security teams discover entitlement sprawl only after an over-privileged role has already been used to move laterally or modify production.
How PAM and CIEM Should Share the Work
Best practice is to assign one accountable owner for the risk program, then split execution by control plane. IAM or identity governance should define entitlement standards, approval paths, and recertification criteria. PAM should manage just-in-time elevation, session controls, and break-glass workflows. CIEM should continuously detect excess permissions, drift, and unused privileges across cloud accounts and subscriptions. That model works because PAM answers who can elevate, while CIEM answers what has actually been granted and where it is risky.
A practical workflow usually looks like this:
- Identity sets policy for least privilege, segregation of duties, and approval thresholds.
- Cloud security validates service-specific permission patterns and resource context.
- PAM issues time-bound elevation for exceptional tasks, not standing admin access.
- CIEM continuously flags toxic combinations, orphaned roles, and permission creep.
- Both teams feed a shared remediation queue so revocation and redesign happen together.
This matters because cloud entitlements are often attached to roles, groups, service accounts, and automation pipelines, not just humans. NHI programs make that risk visible, especially in incidents like the Snowflake breach and the Azure Key Vault privilege escalation exposure, where identity misuse and overbroad access amplified impact. The operating rule is simple: PAM controls the moment of privilege, CIEM controls the persistence of privilege, and neither should own the full picture alone. These controls tend to break down in multi-cloud environments with self-service infrastructure, because entitlement drift outpaces manual review cycles.
Where the Ownership Model Breaks Down
Tighter entitlement governance often increases review overhead, requiring organisations to balance faster delivery against stronger control. The tradeoff becomes real when platform teams, IAM teams, and security operations each believe they own the same permission set but measure success differently. There is no universal standard for this yet, but current guidance suggests the accountable owner should be the function that can enforce policy end to end, with cloud security and identity sharing operational responsibility. That typically means a RACI where one team owns risk acceptance, another owns detection, and a third owns remediation.
Edge cases matter. In platform engineering teams, CIEM may see excessive rights long before IAM can explain why they exist. In regulated environments, PAM may own administrator workflows while a cloud center of excellence owns service-role design. In agentic or highly automated environments, entitlement risk shifts even faster because machine-issued access changes with workload state. The 2024 ESG Report: Managing Non-Human Identities shows how widespread NHI exposure already is, which is why ownership must include lifecycle review, not just provisioning. For teams modernising governance, the practical answer is to align policy, enforcement, and review under one shared operating model rather than debating tool ownership in isolation.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10, OWASP Agentic AI Top 10 and CSA MAESTRO address the attack and risk surface, while NIST CSF 2.0 and NIST Zero Trust (SP 800-207) set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-03 | Entitlement creep and weak rotation of machine access are central to shared PAM/CIEM ownership. |
| OWASP Agentic AI Top 10 | A-05 | Autonomous workloads change entitlement risk dynamically, which static ownership models miss. |
| CSA MAESTRO | MAESTRO maps well to shared governance across identity, cloud, and privileged access controls. | |
| NIST CSF 2.0 | PR.AC-4 | Least-privilege access reviews are directly relevant to cloud entitlement governance. |
| NIST Zero Trust (SP 800-207) | POLP | Zero Trust requires policy enforcement on every access decision, including cloud entitlements. |
Define a single review path for NHI entitlements and revoke unused or excessive access on a fixed cadence.
