RBAC: Role-Based Access Control in Cybersecurity
Most common; some say 'R-B-A-C'.
RBAC stands for Role-Based Access Control. Role-based access control assigns permissions to roles rather than individual users. Users gain access by being placed into roles that match their job function, which simplifies permission management at scale.
How RBAC Is Used in Cybersecurity
GRC analysts review role definitions during access audits to spot over-provisioned accounts. Security architects design RBAC hierarchies that enforce least privilege across the organization. Engineers implement RBAC policies in cloud platforms, applications, and Kubernetes clusters.
