"Don't lose sight of security. Security is a state of being, not a
state of budget. He with the most firewalls still does not win.
Put down that honeypot and keep up to date on your patches. Demand
better security from vendors and hold them responsible. Use what
you have, and make sure you know how to use it properly and effectively."
