Recently, I received an article from GCN about changing the trust method on a network to trusting no one, including PCs on the private network. It reminded me of an idea I have been toying with for years: firewalling our datacenter off from everyone, including our users. In a similar fashion to the article, it makes perfect sense when you break it into simplest form. Treat everyone as if they are the enemy and your defenses will be better.
