TL;DR: Group based access control reduces manual permission assignment, but the article also shows how stale memberships, overlapping groups, and weak audit discipline still create access drift and compliance risk, according to Zluri. The governance problem is not grouping itself, but whether identity lifecycle controls keep group membership, time-bound access, and least privilege aligned as roles change.
Editorial analysis by NHI Mgmt Group, based on content published by Zluri: “Understanding Group Based Access Control for Better Security”.
By the numbers:
- 63% of organisations struggle with managing access permissions across their workforce, creating confusion and compliance risks.
Key questions
Q: What breaks when lifecycle management is separated from access policy design?
A: The organisation ends up automating grants and removals without a stable model of entitlement intent.
Q: Why do overlapping groups create governance risk in IAM programmes?
A: Overlapping groups can stack permissions in ways that are hard to interpret, especially when a user belongs to multiple role, project, or admin groups.
Q: How can security teams tell whether group based access control is working?
A: Group based access control is working when membership matches current role, unused groups are removed, and access reviews consistently find no excess rights.
Practitioner guidance
- Map effective access across group inheritance Review where users accumulate permissions through multiple groups and identify combinations that exceed role intent.
- Tie group changes to lifecycle events Connect department moves, project exits, and leaver events to automatic group membership updates so access does not outlive the role that justified it.
- Retire unused and duplicate groups Create an owner for every group and remove stale, redundant, or exception-based groups that no longer map to a current business need.
Bottom line: Group based access control can reduce manual assignment, but it does not remove the need for lifecycle governance over membership and exceptions.

Group based access control is only as strong as the lifecycle discipline behind it. The model simplifies administration, but it does not solve authorisation governance on its own. When membership changes are not tied to joiner-mover-leaver controls, the organisation merely relocates complexity from individual grants to group sprawl, which is harder to see and easier to rationalise.
A question worth separating out:
Q: Should organisations use time-bound access or permanent groups for temporary work?
A: Organisations should use time-bound access for temporary work because permanent membership tends to survive the task that justified it. Expiry controls reduce lingering access, but they still need ownership and review so exceptions do not become hidden standing privilege.
