Top Segregation of Duties Conflicts and How to Fix Them

An SoD conflict is not about a single permission.

It is about a combination that should not exist together.

Individually, each access right may be valid. Together, they remove separation between actions. That is what creates exposure.

In most systems, these are known as “toxic combinations.” The term sounds dramatic, but the idea is simple — certain roles should never be assigned to the same person.

You will usually see these conflicts in:

• Finance and ERP systems
• HR and payroll platforms
• IAM and provisioning workflows
• Privileged access environments

Anywhere there is a process with more than one step, there is a chance for overlap.

Why SoD Conflicts Are Dangerous

The risk is not theoretical.

When separation is missing, control is missing.

• A user can complete an entire transaction without oversight
• Errors go unnoticed because there is no second checkpoint
• Audit teams flag these combinations quickly

In some cases, it leads to fraud. In others, it is just a mistake that went too far. Either way, the outcome is the same — lack of control.

Most SoD conflicts don’t stand out immediately.

Individually, each permission looks valid. The issue appears only when certain actions sit with the same user. That is when control disappears.

Here are some of the most common segregation of duties conflicts seen in real environments.

1. Create and Approve Payments

In many finance systems, one user ends up with both permissions — entering a vendor invoice and approving the payment.

Nothing looks wrong at first. The same person is just “handling the process.” But there is no second check anywhere in that flow.

If something is entered incorrectly, or intentionally changed, it moves forward without review.

The fix is straightforward but often delayed. The person creating the transaction should not be the one approving it. Even a small separation reduces risk immediately.

2. Request and Approve Access

This one shows up often in IAM workflows.

A user raises an access request and, due to role overlap or workflow gaps, can approve it as well. In smaller teams, this is sometimes seen as convenience.

Over time, it leads to silent privilege growth.

Access gets approved faster, but without independent validation. That is where the risk builds.

Separating the approval path — even if it adds one extra step — makes a clear difference here.

3. Create and Modify User Accounts

Administrative access tends to accumulate.

An IAM admin might have the ability to create user accounts and also assign roles, including privileged ones. This is not always intentional. It usually happens because the admin role was never split properly.

The concern is not the action itself, but the lack of visibility.

If one person can create identities and elevate them, there is no checkpoint. No one else sees the change.

Breaking this into two steps — creation and privilege assignment — restores that visibility.

4. Create and Post Journal Entries

This is a classic ERP issue.

A finance user enters accounting data and also posts it. It keeps the process fast, but removes review entirely.

Even without malicious intent, errors can move straight into financial records.

Separating entry from posting adds friction, but that friction is intentional. It forces validation before finalization.

5. HR and Payroll Access Combination

This one usually appears in HR systems.

The same person updates employee records and approves payroll. On paper, both tasks sit within HR. In practice, combining them creates a gap.

Changes to employee data can directly affect payroll outcomes, with no independent check.

The safer approach is to split responsibility. One handles employee data. Another handles payroll approval.

These are not edge cases. They are toxic combinations in SoD that appear when access grows without structure.

Most teams don’t set out to create SoD conflicts. They show up over time, usually as a side effect of how access is managed.

There isn’t a single cause. It is a mix of small decisions that add up.

Role Changes and Access Creep

This is the most common one.

Someone moves to a new role. They get new permissions. The old ones are not removed.

Nothing breaks immediately, so it goes unnoticed. Months later, the same user holds access across multiple functions.

That is how common SoD violations build quietly.

Manual Provisioning Processes

When access is handled through emails or spreadsheets, consistency drops.

Approvals depend on who is available. Context is often missing. Decisions are made quickly just to move things forward.

Over time, this leads to overlapping permissions without anyone tracking the full picture.

Lack of an SoD Matrix

Some organizations never formally define what counts as a conflict.

Without a clear list of incompatible roles or permissions, everything depends on individual judgment.

That works for a while. Then systems grow, teams expand, and decisions become inconsistent.

This is where segregation of duties conflicts start slipping through.

Emergency or Temporary Access

Access is often granted for a reason — a production issue, a project deadline, a short-term need.

The problem is not the access itself. It is what happens after.

Temporary access stays longer than intended. Nobody comes back to remove it. Over time, it becomes permanent.

These exceptions are one of the biggest sources of hidden risk.

None of these causes are unusual. That is why SoD conflicts are so common, even in organizations with strong policies.

You don’t usually “see” SoD conflicts by looking at one system or one user at a time.

They show up when access is viewed together — across roles, across applications, across workflows. That is why detection needs a bit more structure.

Build an SoD Conflict Matrix

Start by defining what should never exist together.

This is not a long theoretical document. It is a working list. Which roles conflict? Which actions should be separated?

For example, vendor creation and payment approval. Or access request and approval.

Without this baseline, detection becomes guesswork.

Most teams build this once and forget it. That is where problems begin. It needs to reflect how processes actually work today, not how they worked a year ago.

Review High-Risk Systems First

Trying to scan everything at once rarely works.

Focus on systems where the impact is higher — ERP, finance, HR, and privileged access layers.

These are the areas where segregation of duties conflicts tend to cause real damage, not just minor issues.

Once these are covered, you can expand gradually.

Run Regular User Access Reviews

Even with defined rules, some conflicts slip through.

Reviews help surface them.

Managers or system owners look at existing access and question whether it still fits the role. This is often where hidden overlaps come to light.

It is not the fastest method, but it is effective when done consistently.

Use Automated Detection Tools

Manual checks do not scale.

As systems grow, access relationships become harder to track. This is where IAM or IGA tools help.

They monitor access continuously and flag toxic combinations in SoD as they appear, not months later.

This reduces the dependency on periodic clean-ups.

Detection is less about a single tool and more about visibility. Once you can see the overlap, fixing it becomes easier.

Finding SoD conflicts is only half the work. The harder part is deciding what to do next without breaking day-to-day operations.

In most cases, the fix is not complex. It just needs clarity on ownership and roles.

Remove Excessive Access

Start with the obvious.

If a user holds two conflicting permissions, one of them has to go. The question is which one aligns with their current role.

This is where many teams hesitate. Access is left unchanged to avoid disruption. That delay keeps the risk in place.

Removing the extra permission is usually the cleanest fix.

Reassign Responsibilities

Sometimes both permissions are required, just not by the same person.

Instead of forcing one user to handle everything, split the responsibility. One handles the action, another handles approval.

This keeps the process intact while restoring separation.

It may feel slower at first, but it creates a clear checkpoint.

Apply Compensating Controls

There are situations where access cannot be split immediately.

Short-term projects, production issues, or small teams may require temporary overlap.

In those cases, additional checks need to be added.

Extra approvals, activity monitoring, or audit logs can act as temporary controls. They do not remove the conflict, but they reduce the risk until a proper fix is in place.

Automate Future Prevention

Fixing one issue manually does not prevent it from happening again.

The same SoD violation examples tend to repeat unless rules are enforced at the system level.

Once a conflict is identified, it should be added to SoD policies so it gets flagged or blocked next time.

This is where SoD remediation moves from reactive to preventive.

Remediation works best when it is consistent. Not every case needs escalation, but every case needs a decision.

Fixing issues once is not enough. If the process stays the same, the same SoD conflicts come back.

Prevention is mostly about keeping things simple and consistent.

An SoD matrix should exist, but more importantly, it should stay current. Roles change, systems change, and the matrix has to keep up with that. If it does not reflect real workflows, it stops catching real problems.

Access requests should pass through SoD checks automatically. Not as a separate review later, but as part of the provisioning flow. That is where most conflicts can be stopped early.

High-risk areas need more attention. Finance systems, HR platforms, and privileged access should not wait for annual reviews. Looking at them quarterly, or even more frequently, keeps things under control.

Least privilege also plays a role here. When users only have what they need, the chance of segregation of duties conflicts drops naturally. Over-permissioned roles create more overlap.

Finally, SoD should not work alone. Combining it with regular access reviews helps catch what slips through. One prevents, the other corrects.

Most issues do not come from missing controls. They come from controls not being applied consistently.

At some point, tracking SoD conflicts manually stops being reliable.

Too many systems. Too many roles. Too many small exceptions that never get revisited.

This is where SecurEnds comes in.

Instead of waiting for periodic reviews, SecurEnds keeps a continuous watch on access across applications. When a toxic combination appears, it is flagged immediately with context.

• Automated detection of segregation of duties conflicts across systems
• User access certification campaigns to validate existing permissions
• Real-time alerts when new violations appear
• Workflow-driven remediation to assign fixes to the right owners
• Audit-ready reporting with a clear history of decisions

The focus is not just on finding issues, but on closing them without slowing down operations.

See how SecurEnds helps you detect toxic access combinations and automate SoD remediation.

SoD conflicts are not rare. They are one of the most common gaps in identity governance.

They do not usually come from bad intent. They come from access growing without enough checks.

The impact, however, is real — fraud risk, policy violations, and audit findings.

The right approach is straightforward in principle. Identify conflicts early. Fix them quickly. Prevent them from returning.

That last step is where most teams struggle.

With the right controls and automation in place, segregation of duties conflicts become manageable instead of recurring problems.

What is an SoD conflict?

It is a situation where a user holds two or more permissions that should not exist together. These combinations remove separation between actions and approvals.

What are the most common SoD violations?

Typical examples include users who can create and approve payments, approve their own access requests, or manage both user creation and privilege assignment.

How do you detect toxic combinations in access rights?

By defining conflict rules and reviewing access across systems. IAM and IGA tools can monitor these combinations continuously and flag violations.

Can user access reviews identify SoD conflicts?

Yes, reviews can highlight existing conflicts. However, they detect them after access is already assigned, which is why preventive controls are still required.

What is the best way to fix an SoD violation?

The simplest approach is to remove one of the conflicting permissions. If both are temporarily required, responsibilities should be separated or additional controls added.
