There are several implementations of this idea; cfengine being
perhaps the most popular. If you're only managing a few hosts, you
could probably also use a versioning sysem like CVS or SVN to
achieve a similar effect.

This is why 'defense in depth' has become a popular mantra for
infosec people of late. Defending the perimeter often isn't enough,
especially in difficult-to-control environments (like some
businesses or most universities). Centrally administered host
firewalls often help plug holes that can't be covered on the
perimeter.
