Separation of duties (SoD) is a concept in security and risk management that restricts the ability for a single individual to both create and approve access to a sensitive system. By dividing tasks and privileges across multiple people or systems, SoD ensures that a single point of failure or malicious intent does not compromise the system.
History of the Origin of Separation of Duties and the First Mention of It
Separation of duties originated in the financial industry as a method to prevent fraud. It was first mentioned in the 1930s as part of the U.S. federal government’s securities regulation. The concept was later formalized in computer science and information security during the 1970s, focusing on the prevention of fraud and errors in complex computer systems.
Detailed Information About Separation of Duties: Expanding the Topic
Separation of duties operates on the principle that no single individual should have control over all aspects of any critical transaction. This separation ensures that an individual can’t perform a malicious action without collusion from others.
Examples:
- In a financial system, different people might be responsible for creating, approving, and reviewing transactions.
- In IT, different team members might have responsibility for writing code, testing, and deploying to a live environment.
The Internal Structure of the Separation of Duties: How it Works
The implementation of SoD involves dividing responsibilities among various roles. These can be broken down as follows:
- Creation: Initiating a request or transaction.
- Approval: Validating the accuracy and legitimacy of a request.
- Implementation: Carrying out the approved request.
- Review: Verifying that the request was completed as intended.
The segregation ensures that collusion is required to carry out any malicious activity, thus adding an additional layer of security.
Analysis of the Key Features of Separation of Duties
Some key features of SoD include:
- Reduction of Risk: By spreading tasks among different individuals or systems, the risk of error or fraud is minimized.
- Enhanced Accountability: Clear roles and responsibilities make it easier to track who did what, thus enhancing accountability.
- Compliance Alignment: Many regulatory standards require SoD as part of their compliance requirements, like Sarbanes-Oxley Act (SOX).
Types of Separation of Duties
There are various forms of SoD that can be implemented, divided primarily into two categories:
Organizational SoD
| Role | Responsibility |
|---|---|
| Creator | Initiates actions |
| Approver | Validates actions |
| Implementer | Executes actions |
| Reviewer | Audits actions |
System-level SoD
Different systems are used to perform the tasks, ensuring that no single system has complete control.
Ways to Use Separation of Duties, Problems, and Their Solutions
Uses:
- Fraud prevention
- Error reduction
- Regulatory compliance
Problems:
- Complexity in implementation
- Potential conflicts in roles
Solutions:
- Regular auditing
- Clear definition of roles and responsibilities
- Use of technology to enforce SoD

Perspectives and Technologies of the Future Related to Separation of Duties
Future trends in SoD include integration with artificial intelligence to monitor adherence, automation of checks and balances, and increased focus on hybrid environments that include both traditional and cloud-based systems.
How Proxy Servers Can be Used or Associated with Separation of Duties
Proxy servers like those provided by OneProxy (oneproxy.pro) can enforce SoD by routing requests through different channels. They can segregate the access to sensitive data or operations, ensuring that no single user or system can control all aspects of a transaction.
