TL;DR: Segregation of duties in IAM prevents one user from accumulating conflicting permissions that let them request, approve, and execute sensitive actions, according to SecurEnds. The real risk is not just overprivilege, but control collapse when access reviews and role design fail to keep pace with role changes and temporary approvals.
Editorial analysis by NHI Mgmt Group, based on content published by SecurEnds: “Segregation of Duties in IAM: Preventing Fraud and Policy Violations”.
Key questions
Q: What breaks when separation of duties is not enforced in IAM governance workflows?
A: When separation of duties is weak, the same person can request, approve, and retain conflicting access, which undermines control integrity.
Q: Why do temporary approvals create SoD risk in IAM?
A: Temporary approvals create risk when they outlive the task that justified them.
Q: How do teams know whether an SoD matrix is still accurate?
A: An SoD matrix is still accurate only if it reflects current roles, workflows, and approval paths.
Practitioner guidance
- Define incompatible entitlement pairs Build and maintain a conflict matrix for the roles and actions that create real business risk, starting with finance, HR, privileged administration, and approval workflows.
- Embed SoD checks in provisioning Make the access request workflow reject or escalate conflicting combinations before approval, so separation is enforced at the point of entitlement creation.
- Review temporary access for persistence Track emergency, project, and exception-based permissions separately so they can be removed when the original justification ends.
Bottom line: Segregation of duties in IAM fails when access accumulation, temporary approvals, and role changes are not reconciled quickly enough to preserve separation.

Segregation of duties fails first as a governance drift problem, not a policy gap. The article describes a common IAM pattern: access accumulates through role changes, temporary approvals, and incomplete cleanup. That means the programme is not being defeated by a missing rule, but by rules that no longer match the current entitlement state. Practitioners should read SoD as a control that decays when lifecycle discipline weakens.
A few things that frame the scale:
- U.S. fraud losses are projected to reach $40 billion by 2027.
A question worth separating out:
Q: What do auditors look for when reviewing separation of duties controls?
A: Auditors look for evidence that no one person can complete high-risk actions without checks and balances. That includes toxic access combinations, real-time control enforcement, and records showing conflicts were detected and resolved. Teams also need to show that approval workflows prevent conflicting access from being granted in the first place.
