Read The Visible Ops Handbook [1], implement what they talk about, it is an easy read too. On the tools site: puppet [2]. Puppet allows you to bake these controls into your infrastructure and monitor if things change.

p.s. I also read "The Phoenix Project" [3] a couple days ago and it give some good ideas on how to stop in insanity.
