Why does least privilege keep breaking down across AWS, GCP and Azure?

TL;DR: P0 Security's analysis of AWS, GCP and Azure finds least privilege breaks down when privilege persists beyond the task. Practitioners need lifecycle governance that ties inventory, usage review, and just-in-time elevation into one policy.

Editorial analysis by NHI Mgmt Group, based on content published by P0 Security: “Rolling out/enforcing least privilege in practice in AWS/GCP/Azure”.

Key questions

Q: Why do excessive user permissions create security risk?

A: Excessive permissions expand the amount of data, apps, and administrative capability a single account can reach, so any misuse or compromise has a larger blast radius.

Q: How do security teams know whether least privilege is actually working?

A: Least privilege is working when identities have narrowly scoped permissions, unused credentials are removed or quarantined, and repeated access reviews consistently shrink entitlements.

Q: What breaks when standing privileges are left in place for cloud infrastructure changes?

A: Standing privileges increase the chance that a routine change can affect shared systems far beyond the intended task.

Practitioner guidance

  • Inventory every cloud principal List users, groups, roles, service accounts, and service principals across AWS, GCP, and Azure before attempting any rightsizing or JIT rollout.
  • Correlate permissions with real usage Compare policy grants with trail logs and analyzer results so you can see which permissions have been unused for long periods and which are still required.
  • Remove standing access from high-risk roles Replace persistent elevated access with time-bound elevation for administrative and production-impacting actions, especially where users can affect databases or customer services.

Bottom line: Least privilege in multi-cloud fails when privilege persists beyond the task, especially across both human and non-human identities.

Standing privilege is the governance failure least privilege is really trying to eliminate. The article shows that the problem is not simply excess permission count, but access that survives longer than the task that justified it. That makes duration, not just scope, the decisive control variable. Practitioners should treat persistent entitlement as a lifecycle defect, not a cloud hygiene issue.

A few things that frame the scale:

A question worth separating out:

Q: How should security teams handle just-in-time access for humans and NHIs?

A: Teams should treat just-in-time access as the operational form of least privilege, not a separate convenience feature. The goal is to start from zero standing privilege, grant access only for the task, and revoke it as soon as the task ends. That model has to cover both human users and non-human identities.
