To have all locked :
Go to "Security" in Sysprefs, there is an option to have OSX demand the admin password for all delicate settings in Sysprefs, thus having most of the settings locked again.
To confirm : mine is also unset, some options in sysprefs are pre-unlocked. But with above setting you can revert it to stronger security.
Can't remember if I checked that security options before the update. This is my backup Lion which pretty much is unmodified, the one I used before I have erased.
