When conflicting access cannot be eliminated, organisations should design and implement compensating controls that reduce the residual risk. That usually means mapping business and IT controls to the specific conflict, then monitoring the activity with audit trails, alerts, and exception handling. Continuous Controls Monitoring can help where business constraints force limited segregation.
Why SoD Conflicts Change the Control Problem
When separation of duties conflicts cannot be removed from existing roles, the issue stops being a clean design problem and becomes a residual-risk problem. The role is still in production, so the organisation has to accept that some users can perform combinations of actions that would normally be split, and the control objective shifts to constraining, detecting, and proving how that access is used.
That is why compensating controls matter. They do not erase the conflict, but they can make it materially harder for a conflicted role to misuse access without detection. In practice, the question becomes whether the business can tolerate the conflict only if the surrounding controls are strong enough to bound the risk.
A useful way to think about the problem is to map the conflict at the business-process level first, then translate it into the exact technical actions the role can take. For example, if one role can both create and approve a transaction, the risk is not just broad access, it is the ability to complete an end-to-end fraud path unless independent review, transaction-level logging, or workflow enforcement interrupts it.
What Compensating Controls Need to Cover
The most effective compensating controls are the ones that break the unsafe path, not just add paperwork around it. That usually means tightening approvals, separating the evidence trail from the actor performing the action, and ensuring alerts are triggered on the specific combinations of events that represent misuse. Where the conflict is structural, controls should be designed around the high-risk action, not around the role name.
- Audit trails should be complete enough to reconstruct who did what, when, and under which exception.
- Alerts should focus on the conflicted action path, especially unusual timing, volume, or beneficiary changes.
- Exception handling should be explicit, time-bounded, and reviewed by someone outside the conflicted chain.
- Continuous Controls Monitoring can help by checking whether the compensating controls are actually operating, not just documented.
For organisations with recurring sod conflict, the practical aim is to reduce the chance that the same person can both initiate and conceal a harmful action. That is a control-design issue as much as an access issue, and it becomes more important as the number of exceptions grows.
The supporting evidence can be direct and operational. NHI Mgmt Group’s Ultimate Guide to NHIs reports that 97% of NHIs carry excessive privileges, which is a reminder that overbroad access often persists when organisations rely on informal control assumptions rather than enforced limits.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST CSF 2.0 and CIS Controls v8 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | PR.AA — Identity Management, Authentication, and Access Control | SoD conflicts are access-control failures that need bounded authorisation and monitoring. |
| DE.CM — Continuous Monitoring | Continuous Controls Monitoring is central when compensating controls must prove ongoing effectiveness. | |
| Recommendation — Constrain conflicted access with enforced approval boundaries and monitored exception handling. Continuously monitor conflicted activity and alert on control failure signals. | ||
| CIS Controls v8 | 6 — Access Control Management | Compensating controls for SoD exceptions depend on account rights, approvals, and review. |
| Recommendation — Review and restrict conflicted privileges, then document and enforce exception controls. | ||
Practitioner Guidance
What to verify: Confirm that each SoD exception has a named owner, an expiry date, and an evidence trail showing which compensating controls are active for that specific conflict. If you cannot show how the conflict is monitored in production, the exception is not really controlled.
Decision rule: If the same role can both create and approve the same business event, require an independent review step or a system-enforced control before accepting the exception. If the only safeguard is policy text, treat the residual risk as high.
What to measure: Track exception volume, time-to-review, alert fidelity, and the percentage of conflicted actions that receive post-event review. Rising exception counts are usually a sign that the role model is drifting away from the process model.
Practitioner takeaway: Unremovable SoD conflicts should be treated as bounded exceptions, not normal access, and the test is whether the surrounding controls can reliably detect and interrupt misuse before the conflict becomes an incident.
