The art of war is of vital importance to the State. It is a matter of life and death, a road either to safety or to ruin. Hence it is a subject of inquiry which can on no account be neglected.
- Sun Tzu, The Art of War
The ancient Chinese military general Sun Tzu might have been around long before the Internet was a thing, but he sure knew how to make an impression on the world. In his extremely influential book on ancient Chinese warfare, The Art of War, he says that "every battle is won before it's ever fought." This applies to protecting your IT network, too.
