TL;DR: Access decisions are moving from owner-driven permissions to role-based control and attribute-based policy, according to StrongDM’s overview of DAC, RBAC, and ABAC, with the article warning that traditional PAM deployments leave gaps across databases, cloud, Kubernetes, and more. The deeper issue is that these models still assume access can be cleanly assigned and maintained at scale, which breaks down as NHI estates grow.

Questions worth separating out
Q: How should security teams choose between DAC, RBAC, and ABAC for access governance?
A: Choose the model that best matches how stable your identities, resources, and policies really are.
Q: Why do access control models break down as identity estates get more complex?
A: They break down when governance depends on manual upkeep that cannot keep pace with change.
Q: What do organisations get wrong about RBAC in large environments?
A: They often treat RBAC as a permanent simplification rather than a living design.
Practitioner guidance
- Inventory access by control model Map where DAC, RBAC, and ABAC are actually used across applications, infrastructure, and identity platforms.
- Audit role sprawl for RBAC decay Review whether roles still represent stable job functions or have become exception containers.
- Validate attribute quality before expanding ABAC Check whether the attributes used in policy decisions are current, authoritative, and consistently populated across systems.

Access control failures in modern environments are usually lifecycle failures first, model failures second. DAC, RBAC, and ABAC all depend on someone keeping permissions current, but large identity estates make that upkeep uneven. When owners, admins, and platform teams all participate in access decisions, recertification and removal lag behind real usage. Practitioners should treat stale entitlement management as the underlying failure mode, not just a policy design issue.
A few things that frame the scale:
- 1 in 4 organisations are already investing in dedicated NHI security capabilities, with an additional 60% planning to do so within the next twelve months, according to The State of Non-Human Identity Security.
- Only 1.5 out of 10 organisations are highly confident in their ability to secure NHIs, which shows how quickly governance confidence falls behind operational complexity.
A question worth separating out:
Q: How can teams tell whether ABAC is actually improving access control?
A: ABAC is working only when attribute data is current, complete, and consistently sourced across systems. If policies are precise but the underlying identity or resource attributes are stale, the control creates false confidence. Good ABAC should reduce manual exceptions and make policy decisions more explainable, not more opaque.
