# Example: Security by inclusion

To set up security for a system that has two restricted graphic displays (Boiler and Reactor), and different users with different restrictions to access, you could do the following:

In the Graphics editor:

- Assign security code A to the graphic display Boiler.
- Assign security code B to the graphic display Reactor.
- Assign no security code to other displays.

In the Runtime Security editor:

- Turn off (N) the access rights to code A for all User1 type users. These users can log on, view all the displays except the Boiler, and log off.
- Turn off (N) the access rights to code B for all User2 type users. These users can log on, view all the displays except the Reactor, and log off.
- Turn off (N) the access rights to both codes A and B for default users. These users can log on, view all the displays except the Boiler and the Reactor, and log off.
