I don't know if it would be useful or relevant or maybe it's already in there, but it occurred to me that maybe requiring a password to change rules? I know that since it's assumed you are the Administrative user that you have permission to do this, and maybe I'm too paranoid, but it seems like a good idea to me.
I believe that was added in the final release. Your password is now required to promote processes into the Admin zone or to change rules. This is an option, however, and must be turned on via the Options page.
Please let me know if it does not work 100% as expected.
