Which practice involves training different users for the same job role to prevent identity fraud?

The correct practice that involves training different users for the same job role to prevent identity fraud is job rotation. This strategy helps mitigate the risk of fraud by ensuring that no single individual has complete control over a critical process for an extended period. By rotating employees through various roles, organizations can increase oversight and encourage collaboration, ultimately making it more difficult for someone to commit identity fraud without detection.

Job rotation also supports cross-training, allowing employees to gain knowledge and skills in multiple areas, enhancing overall operational resilience. In cases of fraud or misconduct, having multiple trained individuals who can take on similar responsibilities means that an organization can identify discrepancies more easily and maintain continuity in operations.

In contrast, mandatory vacation focuses on ensuring that employees take time off to help uncover any potential fraudulent activities by allowing another employee to review their work. Least privilege is a principle that limits access rights for users to the bare minimum required to perform their job functions, thereby reducing the risk of misuse of sensitive information. A business impact analysis (BIA) evaluates potential impacts of disruptions to business operations but does not directly relate to training users to prevent identity fraud.
