RBAC ensures __________ within an organization by limiting access to only necessary resources.

Role-Based Access Control (RBAC) is a security approach that restricts system access to authorized users. It ensures access control within an organization by limiting access to only necessary resources based on the roles of individual users. RBAC helps prevent unauthorized access and minimizes potential security risks by assigning permissions based on job responsibilities or hierarchical levels within the organization. This enhances data security and protects sensitive information from unauthorized users.
