Cant turn firewall on?

[Mikalias]

I got an Imac I7 a few weeks ago and went to the system preferences and tried to turn on my firewall but it is ghosted. It looks like I have to have something else done before the firewall will work? Anybody got any idea what I have to do to turn it on?

You may need to click the padlock at the bottom that's labelled "Click the lock to make changes" and enter an admin user name and password. That should then enable the controls to start the firewall
