Burlington, Mass.-based network security and management solutions provider Arbor Networks today released its 2012 Worldwide Infrastructure Security Report which offers an unsettling analysis of the evolving distributed denial of service (DDoS) threat for both service providers and enterprises. “It’s the easiest way to break down a company or attack a network and in many ways we’re seeing it as part of a broader set of attacks that are more sophisticated and conducted by nation states.” Today, according to the report, the threat is even greater, morphing into something called hybrid or multi-vector attacks in which hackers use a variety of channels, devices, and tactics to launch their assaults, leaving data centers especially vulnerable.
