Which security testing technique focuses on identifying potential vulnerabilities related to user roles and permissions?

Role-based access control (RBAC) testing is a security testing technique that focuses on identifying potential vulnerabilities related to user roles and permissions within a database system. It involves testing various scenarios to ensure that users are granted appropriate access privileges based on their roles and responsibilities. RBAC testing helps mitigate security risks associated with unauthorized access and privilege escalation, enhancing the overall security posture of the database.
