The Cyber Grand Challenge (CGC) is a tournament for fully automated network defense, DARPA says. Others call it the world's first tournament to see who can build the best fully automatic network defense system. The CGC will pit teams that will create automated systems that will compete in real-time to evaluate software, test for vulnerabilities, generate security patches and apply them to protected computers on a network. The CGC's goal is to vastly improve the speed and effectiveness of IT security against escalating cyber threats, DARPA says. The winning team from the CGC finals would receive a cash prize of $2 million, with second place earning $1 million and third place taking home $750,000.
