Large Scale DDoS Attacks
U.S. banks have spent a lot of time investing substantial resources to defend distributed denial-of-service (DDoS) attacks. They are simple and don't require a lot of resources.
While the attacks are not new, businesses and attackers have been playing a cat and mouse game, said Johannes Ullrich, chief research officer at the SANS Institute, told RSA Conference attendees. Attack tools are getting better at tricking DNS anti-DDoS defenses, he said. Attacks are getting larger, up to over 40 gigabits per second. The attacker only needs 2,000 bots to carry them out, Ullrich said.
