Separation of duties (SoD), also referred to as segregation of duties, is the principle that no user should be given total control over sensitive systems, processes, or activities. For example, one person is not able to complete a task without another person who acts as a check, the 7 best business debt management companies for 2021 or access can be limited to a set number of times. Separation of duties is intended to prevent security compromises, such as errors, fraud, misuse of information, sabotage, and theft. An individual should not be in a position to initiate, approve, and review the same action.

Also, the accounting/reconciling function, and the asset (e.g., money, inventory) custody function should be separated among employees. In all of these scenarios, the odds of a negative outcome for your business rise, thereby increasing your organization’s risk level. Giving one person or group too much control within your business’s processes opens the door for unchecked errors and possible fraud–both of which can result in financial loss, reputational damage, and compliance violations.

The second alternative generates huge matrices, but keeps them aligned with the existing representation of processes and to their practical implementation. The following best practices can help your organizations reduce the risk of SoD violations. In the United States, the Sarbanes-Oxley Act of 2002 (SOX) specifies the need for the separation of duties. The objective is to safeguard against accounting fraud where financial statements are falsified. Policy Manager™ is designed for organizations with complex segregation of duties requirements. Our SoD Insight is ideal if your organization is new to segregation of duties.

Segregation of Duties is an internal control that prevents a single person from completing two or more tasks in a business process. Organizations require Segregation of Duties 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. Segregation of Duties (SoD) is an internal control involving tasks and responsibilities so that no single individual has unchecked authority over a critical business process.

Authorization, Verification and Managerial Review should not be performed by the same person. However, although it is less than optimal, the Principal Investigator (PI) may be allowed to perform all three functions when adequate Mitigating or Compensating Controls are in place. An SoD violation occurs when an employee abuses their role and access — usually deliberately — to perform a prohibited action. The prohibition may be in place due to internal company policy or an external industry regulation. A violation typically occurs when the user has or gains control over more process steps than they are allowed and then misuses that access for their own benefit.

Define and document the responsibilities for separation of duties

For many organizations, separation of duties is a compliance requirement or part of compliance programs. Organizations should regularly review the program to ensure that related controls and processes meet evolving requirements. In instances where duties cannot be fully segregated, based on the matrix presented above, Mitigating or Compensating Controls must be established.

Error prevention By assigning different tasks and responsibilities to individuals or teams, separation of duties helps organizations identify errors in a timely fashion. This helps prevent time lost with corrections at best and legal issues and compliance violations at worst. In this administrative area, fraud and error are both common risks that segregating of responsibilities and tasks is meant to minimize. When segregating duties in payroll, it is common to have one employee responsible for the accounting portion of the job and another responsible for signing off on checks or authorizing funds disbursal. Segregation of duties is critical because it ensures separation of different functions and defines authority and responsibility over transactions.

This internal control ensures that more than one person is required to complete the various tasks required to complete a business process. The reason that segregation of duties is so widely used as part of risk management strategies is that it is effective. Segregation of duties has been proven time and again to prevent the abuse of control and any resulting nefarious activity by a single person or by collusion amongst a group.

Applications and cloud technology have proliferated, creating more workflows, integration points, and mitigating controls that must work harmoniously across many applications. Here are five tips to help you elevate your SoD auditing into the next generation. In the matrix above, the person in charge of hiring employees cannot also be in charge of changing compensation or creating paychecks. For example, an organization may have a rule that the person approving timesheets is not allowed to also distribute paychecks. But when someone takes advantage of a control weakness to do both activities for fraudulent purposes, it becomes an SoD violation. Segregation of duties is a common concept in financial and accounting processes.

Appendix A, figure 1, in our Segregation of Duties guide gives an example of how to organize a one-person accounting department with oversight controls. Successfully managing risk across the enterprise is undoubtedly one of the stiffest challenges faced by today’s security professionals. Threats come in many forms and from varying angles, with the risk often raised or lowered by different structural scenarios or behavior patterns within your organization. One such scenario would be allowing one person or group within your organization complete control over a business process or multiple steps within that process. In enterprises, process activities are often described by means of some procedure or in a diagram in some standard notation, such as a business process model and notation. Often, these descriptions are at a level of detail that does not immediately match with duties as previously defined.

They may also have a service-based business unit necessitating a focus on project accounting, requiring a different SoD matrix. For modern-day businesses, segregation of duties (SoD) is a primary requirement to demonstrate compliance with various laws, regulations, and standards. SoD helps ensure that an individual does not have total control over a process or an asset that may result in risk realization. With the help of segregation of duties, an organization breaks up a process among multiple employees for better checks and balances. In this article, we look at how you can approach an SoD exercise for your business.

Segregation of duties is part of a system of essential controls that help prevent and detect the existence of fraud and error in any type of organization. Segregation of Duties as a security control helps prevent the concentration of responsibilities on a single individual. Organizations should make necessary investments for regular analysis of their processes and procedures. Otherwise, they should explore implementing a compensating control for managing the risk if their SoD cannot address the existing risks.

This is a secondary level of controls that provides assurance about the effectiveness of existing SoD controls. In some cases, separation may not be required between control duties such as authorization and verification, which are often delegated to the same authority. Accountability A separation of duties program promotes accountability and transparency within the organization by assigning responsibilities to specific teams and individuals.

When sacrificing efficiency isn’t an option, companies must live with the tradeoff of weaker control and the greater risk of fraud because the segregation of duties cannot be implemented or has been reduced. Effective segregation of duties (SoD) controls can reduce the risk of internal fraud through early detection of internal process failures in key business systems. It’s an important control in order to achieve an effective risk management strategy. For example, one person can place an order but another must record the transaction of this order. We can say that Segregation of Duties controls implement an appropriate level of checks and balances upon the activities of individuals.

In IT Control Objectives for Sarbanes-Oxley, 3rd Edition—a fourth duty—the verification or control duty is listed as potentially incompatible with the remaining three duties.

Similarly, the person who pushes code to production cannot carry out the other three tasks. In such cases, SoD rules may be enforced by a proper configuration of rules within identity management tools. Such rules can detect a conflicting assignment in the creation or modification phase and report such violations. A more complex and flexible set of rules is needed if dynamic RBAC is to be applied.
