Another of the NIST documents I have co-authored was just published: Guidelines on Firewalls and Firewall Policy. It is a revision of an old document that was really, really out of date and out of step with current practice. Our revision is not perfect (they never are), but we dragged the content kicking and screaming into present. Big thanks go to Joel Snyder at Opus One and David Newman at Network Test for doing thorough reviews of our first draft; they found dozens of places that needed more work, and the doc came out much better because of their reviews.
