RBAC: Securing Access to Systems and Data

Role-Based Access Control (RBAC) is an access control system that is used to regulate user access to computer systems, networks, and other resources. It is based on the principle that users are assigned to roles, and each role is granted specific permissions or access to resources. RBAC is an effective way to manage access to resources, as it allows administrators to easily assign and manage permissions for multiple users. RBAC also provides a more granular level of control than other access control models, such as discretionary access control (DAC) or mandatory access control (MAC). By assigning roles to users, RBAC allows administrators to control user access to resources based on their roles, rather than individual user accounts. This makes RBAC a more efficient and secure way to manage access to resources, as it reduces the risk of unauthorized access.
