I'll also add that parts of "The Art of War" are as applicable to cyber warfare as to traditional. For example, I used the following quote in my information security classes.
Quote
If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.
