This is a set I made myself, pretty simple (almost too simple - I use other icons now), and I called it Shield at random. My skins are much better, though still simple, so you should check them out too. Search these skins:
Office Clean CC
Desk Wooden CC
Mountain Lion CC
Some of these icons have designs from other people integrated into them, but they're from scattered authors, so I won't list all of them. Lots I just got from here:

Don't rate... I need not know how bad they are - just wanted to share them with whomever might get some use out of them.
