Which control ensures responsibilities are divided to reduce fraud risk in IAM?

Explanation:
Segregation of duties is the control that splits responsibilities across different people or roles to prevent fraud and errors in IAM processes. By ensuring that no single user can complete all steps of a critical task, you create checks and balances. In practice, duties are divided among those who request or obtain access, those who approve access, and those who audit or monitor activity. This means that fraudulent actions typically require more than one person and leave an audit trail, making it harder to conceal wrongdoing. Other controls address separate needs: periodic access reviews validate existing rights, a centralized repository provides a single source of identity data, and metrics/indicators help detect unusual activity—none by themselves enforce the essential division of responsibilities.
