You still can do that without expending too much effort.

One way would be to monitor centos-announce, parse the subject lines, copy the security update filenames to a text or database file.  (sqlite is made for this kind of thing.)  You can either keep a list on each machine or have a central data repository, whichever suits you best.

Then all you need to do is have each machine run "yum check-update" on whatever timed basis you wish.  Capture the list of pending updates, compare it against your database, and then do your thing.
