Separation of Duties
Separation of Duties (SoD) is a security and compliance principle that divides critical tasks or responsibilities among multiple individuals or systems to prevent fraud, errors, and unauthorized access. It ensures that no single person has complete control over a process, reducing the risk of malicious activities or mistakes. This concept is widely applied in IT, finance, and regulatory environments to enforce accountability and internal controls.
Developers should learn and implement Separation of Duties when building systems that handle sensitive data, financial transactions, or require high security, such as in banking, healthcare, or government applications. It is crucial for compliance with regulations like SOX, GDPR, or HIPAA, as it helps prevent insider threats and ensures audit trails by distributing authority across roles like development, testing, and deployment.
