Security

I installed AsteriskNow 1.0.2.1

On console screen of asterisknow server I have a window with the title “AsteriskNOW Console Menu”.
The message in this window is:
To configure the system, point your browser to: .
Or, please select any of the following options:
update
console
restart
reset
shutdown
reboot
quit

My question is about security.
Everybody can go on this console and select the option, for example, shutdown ecc…

Is it possible to have the linux classic screen where I can type my credential (for example root + password)
and only after having the windows described over?
Thanks
Andrea
