What is Role-Based Access Control?
RBAC (Role Based Access Control), is also known as Role-Base security. RBAC assigns access permission to users on their role in IT. Only the admin has complete access to the network while the other network engineers do not need full access, some of them just need to monitor and crosscheck the configuration with show commands. Admin can define what user can access as per the user roles.

Why do we need RBAC?

RBAC reduces the risk of cybersecurity and protects against human error, RBAC ensures that admin define users can only access the information and perform actions they need to do as per the role. RBAC is good for large organizations.

What is the Concept behind Role Based Access Control

Admin creates a set of permissions and assigns that permission to the user. For example, user-1 is a junior engineer L-1 and the role is just to monitor interface state. Admin will allow user-1 to only show ip interface brief command to user-1 and now user-1 only access show ip interface brief command not show ip route not configure any and delete anything on the device. Now the security level has been increased because only the admin can configure and delete the configuration.

What are RBAC Views?

Admin creates the Views and views define the commands that a user can access. Mainly we have two types of view. Root view is an admin view where you configure views and superview in this view admin assigns multiple views (users) in superview. Superview can access all the commands that the admin configures the views. Remember these views should be in superview.

(configure the password before configuring any view, if you configure configure then you can lock yourself )
