Rapidly improving warfare technology is utilizing satellite imagery to determine the best tactical moves, and IP communications to relay instructions to soldiers, says Scott Montgomery, vice president of product management for Secure Computing. Protecting these communications is vital, as Israel learned last year when Hezbollah guerillas hacked into radio communications in southern Lebanon, allowing the guerillas to repel tank assaults. "This kind of real-time battlefield data has unbelievable tactical value to military organizations," Montgomery says. "If you're directing military traffic and saying 'shoot here' and the enemy has access to those communications, they're not going to be there when the rocket lands.""
