Separation of Duties
Prevent conflicting access rights and maintain regulatory compliance
What is Separation of Duties?
Separation of Duties (SoD) is a fundamental security principle that ensures no single individual has sufficient access to both initiate and approve a sensitive transaction or process. By distributing critical tasks across multiple people, organizations reduce the risk of fraud, errors, and unauthorized activities.
In enterprise applications, SoD violations occur when users are granted conflicting permissions that, when combined, could enable fraudulent activities or bypass established controls. Visual Guard provides the framework to define, detect, and prevent these conflicts across your application portfolio.
Key Benefits
- Prevent fraud and errors
- Maintain regulatory compliance
- Strengthen internal controls
- Reduce audit findings
- Demonstrate due diligence
Common SoD Conflict Examples
Understanding what constitutes a separation of duties violation
Procurement Conflict
Incompatible permissions:
- Create vendor accounts
- Approve payment to vendors
Risk: A user could create a fictitious vendor and approve payments to it, enabling embezzlement.
Financial Controls
Incompatible permissions:
- Create journal entries
- Post entries to general ledger
Risk: Unauthorized modification of financial records without oversight, compromising financial integrity and compliance.
Security Administration
Incompatible permissions:
- Modify user permissions
- Disable audit logging
Risk: An administrator could grant themselves excessive privileges and hide their actions from audit trails.
Why Separation of Duties Matters
Fraud Prevention
The primary objective of SoD controls is to prevent fraud by ensuring that critical processes require the involvement of multiple individuals. This creates natural checkpoints where irregularities are more likely to be detected.
By design, no single person can complete a fraudulent transaction from start to finish. This significantly reduces both the opportunity and temptation for dishonest behavior.
Regulatory Compliance
Many regulatory frameworks explicitly require separation of duties controls. Standards such as SOX (Sarbanes-Oxley), ISO 27001, NIST SP 800-53, and PCI DSS mandate that organizations implement and document SoD policies.
Failure to maintain adequate SoD controls can result in audit findings, regulatory sanctions, and increased scrutiny during compliance assessments.
Internal Controls
SoD forms a cornerstone of effective internal control frameworks. It provides checks and balances that reduce errors, ensure accountability, and create transparency in business processes.
Organizations with strong SoD controls demonstrate operational maturity and sound governance, building trust with stakeholders, auditors, and business partners.

Comprehensive tools for defining, detecting, and managing separation of duties
Rule Definition
Define incompatible permissions that should never be granted to the same user. Rules can be defined within a single application or span multiple systems, covering complex enterprise scenarios.
Configure risk severity levels to prioritize high-impact conflicts. Document the business rationale for each rule to support audit requirements and ensure organizational understanding.
Risk Simulation
Before assigning roles or permissions, simulate the impact to identify potential SoD violations. The system analyzes existing access combined with proposed changes, alerting administrators to conflicts before they occur.
This proactive approach prevents violations at the source, reducing the need for remediation and maintaining continuous compliance.
Conflict Detection
Automated scans identify existing SoD violations across your user population. Generate reports showing which users have conflicting access and the specific permissions involved.
Establish remediation workflows with approval processes for justified exceptions. Track all violations, resolutions, and compensating controls for audit documentation.
Cross-Application Separation of Duties
Multi-System Risk Management
Many SoD risks span multiple applications. A user might have the ability to create a vendor in an ERP system and approve invoices in an accounts payable application. When managed separately, each system appears compliant, but the combined access creates an exploitable vulnerability.
Visual Guard's centralized architecture enables organizations to define and enforce SoD rules across heterogeneous application environments, providing comprehensive risk visibility that siloed systems cannot achieve.
Practical Implementation
Consider an organization using multiple systems for financial operations:
- ERP System: Manages vendor master data and purchase orders
- AP System: Processes and approves vendor payments
- Banking Portal: Executes electronic fund transfers
Visual Guard can enforce rules preventing users from having "vendor creation" rights in the ERP combined with "payment approval" access in the AP system, even though these permissions exist in completely separate applications.
Compliance and Regulatory Standards
Visual Guard's SoD controls support compliance with major regulatory frameworks and standards
Supported Standards
- SOX (Sarbanes-Oxley): Financial controls and audit requirements for public companies
- ISO/IEC 27001: Information security management system requirements including access control
- NIST SP 800-53: Security controls for federal information systems and organizations
- PCI DSS: Payment card industry data security standard access control requirements
- GDPR: Data protection and privacy regulation compliance through access controls
- NIS2: Network and information security directive requirements
Audit Documentation
Generate comprehensive reports demonstrating SoD compliance for internal and external audits:
- Current SoD rule definitions and their business justifications
- Complete list of identified violations with severity classifications
- Approved exceptions with documented compensating controls
- Remediation history showing when and how conflicts were resolved
- Evidence of periodic review and recertification of access rights
All audit evidence is maintained with timestamps, user attribution, and change history for complete traceability.
Implementation Approach
Defining SoD Rules
Implementing effective SoD controls begins with identifying critical business processes and the access rights involved at each step. Organizations typically start by addressing high-risk financial transactions and progressively expand to other areas.
Visual Guard enables you to:
- Start with standard rule templates for common scenarios
- Customize rules to match your specific business processes
- Define rules at the permission level for maximum granularity
- Document business justifications for each rule
- Assign severity levels to prioritize remediation efforts
Remediation Workflow
When SoD violations are detected, Visual Guard supports structured remediation processes:
- Identification: Automated scans detect existing conflicts
- Assessment: Security teams review violations and determine appropriate actions
- Resolution: Remove conflicting access, reorganize roles, or document justified exceptions
- Approval: Management approves exceptions with compensating controls
- Monitoring: Ongoing surveillance ensures sustained compliance
The entire process is tracked and documented, providing complete audit trails and demonstrating due diligence in addressing SoD risks.

Integrated Access Control Framework
Separation of Duties works seamlessly with Visual Guard's comprehensive access control capabilities
SoD controls are not implemented in isolation. They function as part of Visual Guard's broader access control framework, working alongside role-based access control, access governance, and audit capabilities.
When roles are assigned or modified, the system automatically checks for SoD violations. Access review campaigns can include SoD compliance checks, ensuring managers certify not only that users need their access, but also that no conflicting combinations exist.
This integration means SoD compliance becomes a continuous, automated aspect of access management rather than a periodic manual review process. Security teams gain confidence that SoD policies are enforced consistently across the organization, while auditors receive the documentation they need to verify compliance.
The result is stronger security, reduced compliance burden, and demonstrable due diligence in protecting organizational assets.
