As I understand you are talking about permissions, user permissions.
It seams logic to me to have a UserPremission model to deal with it.
It could have a list of action it is permit to perform and a way to
check public actions.

You can look at http://redmine.org solution of this issue in their
application source.
You can learn a lot from the others.
