Distributed denial of service (DDoS) attacks are a fact of life for most large companies, government agencies, and anyone unlucky enough to be targeted by cybercriminals or hactivists. The attacks, which take companies off the Internet by flooding servers with fake outside connections, require no real technical skills to pull off--just multiple users or a botnet to coordinate attacks.
