How does role-based access control (RBAC) work in NPM, and why is it important?

• A. RBAC means all users have full access.
• B. Users are assigned roles with specific permissions; RBAC enforces least privilege, limiting who can view or modify data.
• C. RBAC is not used in NPM.
• D. RBAC only applies to dashboards.

Answer: (B)

RBAC in NPM works by defining roles that bundle a specific set of permissions and then assigning those roles to users or groups. Each role determines what actions a user can perform and on which resources—such as viewing network performance data, acknowledging or silencing alerts, editing configurations, or managing dashboards. When a user signs in, their roles are checked and access is granted accordingly, so they can only view or modify what their role allows. This directly supports the principle of least privilege: people get only the access they need to do their job, reducing the risk of accidental or intentional changes to critical data. This approach also helps with onboarding, audits, and ongoing security management. Permissions are centralized in roles, so it's easy to adjust access for everyone who reports to a given role or remove access when someone leaves the team. In practice, you can create distinct roles for operators, administrators, and managers, giving each the appropriate level of visibility and control over dashboards, devices, alerts, and configurations. The idea that everyone would have full access or that RBAC isn’t used would undermine security and control, whereas RBAC provides a scalable, maintainable way to manage who can do what in NPM.
