If you waited until now to ask, your problem is executive/managerial in nature. If you're serious, get a consultant to help you evaluate or build a security program (kpmg,mandiant,etc..). You don't need to do one off changes here and there so you can feel safe, you need a functioning program/team that would get you to where you don't need to panic about random world events of all things.
