Broken access control in hybrid cloud: is IAM keeping up?

TL;DR: P0 Security finds broken access control remains the number-one OWASP Top 10 issue because hybrid cloud environments still let authenticated identities act beyond intended scope, as inconsistent enforcement, static entitlements and poor visibility outpace runtime authorization governance. The real gap is continuous entitlement control, not login verification.

Editorial analysis by NHI Mgmt Group, based on content published by P0 Security: “Why broken access control still tops the OWASP Top 10 and what it means for identity security in the era of hybrid cloud”.

Key questions

Q: What breaks when broken access control is treated as a purely application-layer issue?

A: Teams miss the service and token boundaries where authorization actually fails.

Q: Why do static entitlements increase risk in hybrid cloud environments?

A: Static entitlements outlive the systems and tasks they were meant to support.

Q: How can teams tell whether access governance is actually working?

A: Look for short revocation times, low rates of stale entitlements, and repeatable access review outcomes across systems.

Practitioner guidance

  • Implement runtime entitlement governance Continuously discover, evaluate and revoke effective permissions across AWS IAM, Azure AD, Kubernetes RBAC and on-prem directories so that authorization reflects current state rather than stale provisioned access.
  • Replace standing privilege with JIT access Use time-bounded, scope-limited access for admin and operational tasks, and automatically revoke it when the task or session ends so temporary elevation does not become persistent exposure.
  • Measure effective access across control planes Test who can actually reach sensitive resources, not just what the policy files say, and look for toxic combinations that emerge when cloud and on-prem models are combined.

Bottom line: Broken access control in hybrid cloud is primarily an authorization governance problem, not a failure of authentication.

What's in the full article

P0 Security's full article covers the operational detail this post intentionally leaves for the source:

  • The OWASP Top 10 context behind why broken access control remains a top-ranked issue
  • The article's practical comparison of AWS IAM, Azure AD, Kubernetes RBAC and on-prem directories
  • The rationale for moving from periodic reviews to continuous entitlement governance
  • The specific examples of how temporary elevation becomes permanent in hybrid estates

Broken access control is now an identity governance failure, not a developer-only defect: The article shows that the real control gap sits in how permissions are governed across heterogeneous estates. Authentication can be sound while authorization still fails, which is why hybrid cloud exposes IAM as the deciding control plane. Practitioners should treat broken access control as runtime entitlement governance.

A question worth separating out:

Q: What should teams do when user, workload and service account access all cross the same environments?

A: Treat every identity type as part of one authorization fabric. User accounts, service accounts, workload identities and API keys can all bridge production, CI/CD and management planes, so governance must evaluate the combined blast radius, not each environment or identity class in isolation.
