TL;DR: Cloud segregation of duties is harder to enforce in AWS, Azure, and GCP because permissions now shift through IaC, CI/CD, temporary elevation, and non-human identities, according to SecurEnds. The core governance problem is that static review models cannot keep pace with distributed cloud access, overprivileged workloads, and dynamic privilege changes.

Editorial analysis by NHI Mgmt Group, based on content published by SecurEnds: “Segregation of Duties in Cloud Environments (AWS, Azure, GCP)”.

Key questions

Q: What breaks when cloud segregation of duties is enforced only through static role reviews?

A: Static role reviews miss the real control path in cloud environments, where permissions change through pipelines, temporary elevation, and delegated automation.

Q: Why do conflicting cloud privileges create both security and compliance risk?

A: Conflicting privileges let one subject alter infrastructure, approve changes, and hide evidence of those actions without independent oversight.

Q: What signs show that SoD governance is failing in practice?

A: Common signs include users who can both create and approve transactions, admins who review their own privileged activity, recurring access creep, and unresolved toxic entitlement combinations.

Practitioner guidance

  • Define a cloud-specific SoD matrix List prohibited combinations for provisioning, approval, audit, and production access across AWS, Azure, and GCP so conflict detection can run before access is granted.
  • Include non-human identities in access certifications Recertify service accounts, workloads, API keys, and automation identities alongside human users, with the same conflict rules applied to each.
  • Separate IAM administration from audit oversight Ensure the same administrator cannot both assign privileged roles and validate whether those roles were appropriate or compliant.

Bottom line: Cloud segregation of duties weakens when the same cloud identity can request, approve, and exercise access through automated workflows.

Cloud segregation of duties now fails at the permission-state level: The classic model was designed for stable roles and centralized administration, not for cloud access that appears and disappears inside deployment workflows. In AWS, Azure, and GCP, the important control question is no longer who owns the role, but who can create, approve, and exercise it within the same operational chain. Practitioners should treat SoD as a governance problem over mutable permission states, not a static role chart.

A question worth separating out:

Q: How should teams separate cloud administration from audit oversight?

A: Teams should split the authority to grant access from the authority to validate it, and apply that split consistently across AWS, Azure, and GCP. The practical test is simple: no single role should be able to assign privileged access and then certify that same access as acceptable.
