The system matches traffic to access control rules in top-down order by ascending rule number. RBAC grants access based on a user’s role and implements key security principles, such as “least privilege” and “separation of privilege.” Thus, someone attempting to access information can only access data that’s deemed necessary for their role. Identity and access management explained.
