Role-based access control (RBAC) is a way of limiting who can access what on your site and your security system. It grants permissions based on the job title someone holds within the organization. It is based on the idea that different users have different roles and responsibilities, and they only need access to the relevant things to their work.
Role-based access control finds applications in various scenarios; for instance, a security guard may have access to the main entrance, the security office, and the CCTV room but not to the server room, the executive office, or the vault.
Similarly, a manager may have access to the executive office, the conference room, and the staff lounge but not to the security office, the server room, or the vault.
RBAC makes it easier to manage access rights for a large number of users, as you only need to assign them to the appropriate role groups instead of giving them individual permissions. This reduces the risk of human error, unauthorized access, data breaches, and compliance violations.
