A financial institution is implementing a new payment processing system. What principle is BEST applied when requiring that payment initiation and payment approval must be performed by different employees?
Role-based Access
Least Privilege
Defense in Depth
Segregation of Duties
Segregation of Duties (SoD) is a security principle that divides critical functions among different individuals to prevent fraud, errors, and abuse by ensuring that no single person has complete control over a transaction or process. By requiring multiple people to be involved in sensitive transactions, SoD creates a system where critical tasks are distributed among different individuals, making it more difficult for any single person to commit fraud or make errors without detection. In the given scenario, separating payment initiation from payment approval is a classic example of implementing SoD in a financial context.
