From: "Gary L. Jackson" <GARY.L.JACKSONat_private> All: Bruce's remarks prompt me to tell you about a brochure I did for the Joint Staff in the Pentagon: Information Assurance Through Defense in Depth You can find it at http://www.dtic.mil:80/jcs/j6/j6k/did.pdf <http://www.dtic.mil:80/jcs/j6/j6k/did.pdf> One of the key points is that we need to continue to find ways to fight back, just as those who built and improved medieval castle defenses created ways to fight back. I quote from the brochure and put in bold the key phrase: "The dynamically evolving defenses of the medieval castle offer a valuable analogy In that violent age, castles offered secure bases for armed forces to control key terrain. In response to changing threats, they evolved from simple to complex and very strong fortifications, following two principles: (1) increase and strengthen the defensive barriers, and (2) provide means to fight back actively. Castles on strong foundations, often on higher ground, employed successive barriers such as water obstacles, ditches, rings of strong and high walls with overhangs, and towers. Improvements to the walls allowed defenders to engage the attacker, and multiple gates enabled local counterattacks and raids. A small force could hold out against a much larger adversary. Just as the castle protected critical resources, now we must defend our vital military information and actively fight back with appropriate responses." Sincerely, Gary L.
