Performing Segregation of Duties (SOD) Risk Analysis in Dynamics 365 Finance and Operations (D365FO)

In today’s competitive and compliance-driven business environment, safeguarding financial systems against fraud and errors is critical. One of the essential control mechanisms to achieve this is Segregation of Duties (SOD). This practice ensures that no single individual is entrusted with multiple crucial tasks within a business process, minimizing the risk of internal fraud and errors.

Dynamics 365 Finance and Operations (D365FO) provides an integrated solution to help organizations assess and manage SOD risks effectively. By utilizing its security framework, role-based access controls, and analytical tools, businesses can proactively identify conflicts and implement corrective actions to ensure compliance with industry regulations such as SOX and COSO.

This article focuses on how D365FO can simplify the SOD analysis process, helping businesses stay secure and compliant with key industry standards.

Key Components of SOD in Dynamics 365 Finance and Operations (D365FO)

In D365FO, SOD management revolves around the concept of duties, which are groups of related privileges that define what a user can do within the system. Here are the main components that support SOD within D365FO:

• Security Roles, Duties, and Privileges

Security roles are the top-level entities in D365FO’s security framework. These roles group duties and privileges that are necessary for specific job functions. Examples include roles like Accounts Payable Manager or Inventory Clerk, which ensure that users only have access to features related to their tasks.

Roles are assigned to users, linking them to duties and privileges. Proper SOD management involves ensuring that no role encompasses conflicting duties.

• Duties represent specific responsibilities within the system, such as approving invoices or creating purchase orders. By organizing duties into roles, D365FO minimizes the risk of conflicting access rights.
• Privileges are the smallest level of access, defining individual tasks such as accessing forms or menu items. Privileges are grouped into duties, creating a layered approach to access control.

Defining Segregation of Duties Rules

D365FO includes a built-in framework for defining and enforcing SOD rules, which specify which combinations of duties are incompatible and should not be assigned to the same user. For example:

• Conflict Example: If a user is assigned both the "Maintain Vendor Invoices" and "Approve Vendor Invoices" duties, it creates a risk of unauthorized transactions.

The list of these conflicts forms the SOD Framework or SOD Ruleset, which helps ensure that duties are assigned in a way that prevents internal fraud.

Detecting and Analyzing SOD Violations

D365FO offers tools to detect SOD violations and help organizations resolve conflicts effectively. Administrators can use diagnostic tools to run analyses and identify potential violations, ensuring compliance with regulatory standards such as SOX.

• Conflict Resolution: D365FO allows administrators to manage conflicts by reassigning duties or splitting responsibilities between multiple users, helping mitigate the risks associated with SOD violations.
• Mitigation Tools: D365FO integrates ITACs (Information Technology Application Controls) and workflows, which ensure that SOD principles are enforced and transactions are secured.

Configuring SOD Analysis in D365FO

To begin performing SOD risk analysis, the following components should be configured:

1.  Security Roles and User Assignments

Security roles in D365FO group duties and privileges. Users are assigned specific roles, which link them to particular duties and privileges. The role assignments play a crucial role in the SOD analysis process.

• System Administration > Security > Security Configuration
• System Administration > Users > Users
  These sections allow administrators to manage user assignments and security roles within the system, essential for running effective SOD analyses.

2. Creating Segregation of Duties Rules

To create a rule in D365FO that prevents a user from performing both the "Maintain Vendor Invoices" and "Approve Vendor Invoices" duties, follow these steps:

• Navigate to System Administration > Security > Segregation of Duties > Segregation of Duties Rules.
• Click + New to create a new rule.
• Select the conflicting duties and define the risk associated with the conflict. For example, the risk could be "Registering unapproved invoices."

The rule is now created, and the system will alert administrators if a user is assigned conflicting duties.

Detecting and Addressing SOD Violations

Once the SOD rules are configured, the next step is running diagnostics to identify conflicts:

• Go to Security Administration > Security > Segregation of Duties > Segregation of Duties Rules.
• Click Validate Duties and Roles to perform the analysis.
• If a conflict is detected, such as a role containing both "Maintain Vendor Invoices" and "Approve Vendor Invoices," the system will display an error message.

Role Assignment Conflicts:

• If the conflict is detected while assigning a role, administrators are prompted to resolve the conflict before proceeding.

The options are:

• Reject Assignment: The user is not assigned the role due to the SOD violation.
• Allow Assignment: The role is assigned despite the conflict, typically in exceptional cases where the role assignment is required for business continuity.

ITAC Documentation for Conflict Mitigation

ITACs (Information Technology Application Controls) are integral to addressing SOD conflicts in D365FO. These controls are used to document and implement mitigation actions for identified risks.

For instance:

• Define the risk in the system.
• Populate the ITAC information that mitigates the risk, such as requiring additional approvals for conflicting duties.

Summary

Dynamics 365 Finance and Operations (D365FO) provides comprehensive tools to manage Segregation of Duties (SOD). By leveraging security roles, duties, privileges, and SOD rules, businesses can identify conflicts, enforce compliance with regulations, and ensure critical business processes remain secure.

D365FO’s integration with ITACs and workflows enables businesses to address conflicts and mitigate risks, providing a robust solution for maintaining the integrity of financial systems and safeguarding against fraud.
