Offense is fun and it is usually psychologically easy. You can go hunting when you are in the mood. Look at the NVA during the Vietnam War: they attacked when they were ready. The fight was at the time and place of their choosing, and the guys holed-up on base had to deal with the growing tension and threat.
The information war is similar. Offense requires commitment and the ability to focus for long periods of time. Defense requires careful planning and a refusal to take the easy way. Offense usually has the advantage.
These are the Principles of Defense:
- Keep it simple
- Hedgehog Defense (we can to have layers of defense, but not overly complex layers which have a large attack surface)
- Make it harder and more expensive to attack
