Role-based access control (RBAC) is a security method that restricts system access to authorized users based on their roles within an organization. Each user is assigned a specific role, such as administrator, editor, or viewer, which determines what resources they can access and what actions they can perform. This helps ensure that sensitive information is only available to those who need it for their job. By using RBAC, organizations can simplify user management and enhance security. For example, when a new employee joins, they can be quickly assigned the appropriate role, granting them access to the necessary tools and data without compromising security. This streamlined approach reduces the risk of unauthorized access and helps maintain data integrity.
