A new study of Internet service providers (ISP) and their top security concerns lets us know what they're most scared of: armies of zombie computers mounting huge distributed denial of service (DDoS) attacks.The latest Worldwide Infrastructure Security Report
-- this is the third in a annual series from security company Arbor Networks
and the University of Michigan singles out groups of computers mounting large-scale attacks as the top provider fear.
Botnets with their ability to aggregate and coordinate hundreds of thousands of compromised computers into a wide-array platform for DDoS assaults capable of shutting down providers, companies and even governments.
Indeed, the FBI lists botnets as a potential threat to both national and economic security.
Of particular concern in the Arbor report is the finding that attack traffic is growing faster than ISP capacity -- attack volume may be more than twice the data capacity of even recently upgraded backbones.
