Segregation of Duty
Segregation of Duty (SoD), also called separation of duty, refers to a set of preventive internal controls in a company’s compliance policy. Organizations require SoD controls to separate duties among more than one individual to complete tasks in a business process to mitigate the risk of fraud, waste, and error.
In the traditional sense, SoD refers to separating duties such as accounts payable from accounts receivable tasks to limit embezzlement.
For example, a user who can create a vendor account in a payment system should not be able to pay that vendor to eliminate the risk of fraudulent vendor accounts.
Another example is a developer having access to both development servers and production servers. In modern IT infrastructures, managing users’ access rights to digital resources across the organization’s ecosystem becomes a primary SoD control.
Segregation of Duty Policy in Compliance
SoD figures prominently into Sarbanes-Oxley (SOX) compliance. SOX mandates that publicly traded companies document and certify their controls over financial reporting, including SoD.
Following a meticulous audit, the CEO and CFO of the public company must sign off on an attestation of controls. They can be held accountable for inaccuracies in these statements. If it’s determined that they willfully violated SoD, they could even face legal penalties.
Federal regulations such as 21 CFR Part 11 also depend on Segregation of Duty controls. Similar requirements exist across healthcare, financial services, and other industries where protecting records and restricting unauthorized actions are essential.
Proper SoD ensures records are created, modified, and approved only by authorized individuals, reducing operational risk and strengthening regulatory compliance.
How Does Identity Governance Support Effective SoD Policies and Controls?
In today's regulatory landscape, maintaining effective Segregation of Duties (SoD) is crucial for preventing fraud and ensuring compliance. Identity Governance and Administration (IGA) solutions play a vital role in supporting SoD policies by centralizing access management and providing comprehensive oversight. Here's how IGA solutions can enhance your SoD controls and what steps are essential for a thorough SoD control assessment.
The Role of Identity Governance in SoD
Identity Governance solutions help organizations enforce SoD policies by:
Centralizing Access Management
IGA systems provide a unified platform to manage user access across various applications and data sources, ensuring that segregation of duties is consistently enforced.
Continuous Monitoring
These solutions offer real-time visibility into user access, allowing organizations to continuously monitor and adjust permissions to prevent SoD violations.
Compliance Assurance
By automating access reviews and generating audit-ready reports, IGA solutions help demonstrate compliance with regulatory requirements and internal controls.
Ten Essential Steps for SoD Control Assessment
- Prepare rule report from the RBAC controls design matrix
- Gather a list of active application users and role entitlements including privileges and data access
- Identify application configurations that mitigate the inherent SoD risk
- Finalize the access violations report by excluding exceptions and mitigated risks
- Create a remediation plan with corrective actions to update the user assignments and role configurations.
- Scope and add "sensitive" access rules to detect user access to restricted data
- Create a list of exceptions by analyzing the security object items that prevent user access violations
- Detect access rule violations by applying security object items rule logic to filter the user access report
- Perform look-back transaction analysis to detect materialized risks
- Provide an access violation scorecard as evidence of control effectiveness
