Role-based access control (RBAC) is an important model for managing access and security within organizations, offering benefits such as enhanced security, simplified account management, and improved scalability. It involves assigning users to roles, which are then granted specific permissions, allowing for more granular control over access based on job functions. This approach not only limits unauthorized changes and protects company assets in the event of a data breach but also reduces human error and streamlines user management processes. RBAC is flexible and customizable, with pre-defined roles available and the option to create custom roles tailored to an organization's needs. Esper, a company specializing in device management, provides RBAC with roles like Enterprise Administrator and Group Viewer, and supports custom role requests through their console, helping organizations efficiently manage their device ecosystems.
