What role does role-based access control (RBAC) play in network security?

Role-based access control (RBAC) streamlines permissions and strengthens security across organizational networks by assigning access rights based on job roles or functions within an organization. This approach helps ensure that users only have access to the resources and information necessary to perform their job duties, reducing the risk of unauthorized access or data breaches. RBAC simplifies the management of user permissions by grouping individuals with similar roles and responsibilities, making it easier to assign and revoke access rights as needed. By enforcing the principle of least privilege, RBAC limits users’ access to only what is required for their specific role, minimizing the potential for human error or intentional misuse of resources. This granular control over permissions enhances security by reducing the attack surface and helping organizations comply with regulatory requirements.
