Understanding the Modern DDoS Threat



The breadth of cyber threats that an organization must engage with and combat seemingly change on a daily basis. Each new technology, vulnerability or exploit vector results in a new threat that must be protected against. Meanwhile some forms of attack never appear to age - they remain a threat to business continuity despite years of advances in defensive strategy. One particularly insidious and never-ending threat is that of the Distributed Denial of Service (DDoS) attack.

Never far from the news headlines, DDoS attacks are the staple disruptive technique preferred by an increasingly broad spectrum of attackers. While they may be the oldest and most commonly encountered form of cyber attack, defenses against them are often non-trivial and even the best tried-and-tested protection can fail under a sufficiently well conceived attack.

This paper examines the technology, coordination tactics and motivations behind the DDoS attacks likely to pose a risk to Internet accessible businesses now and in the immediate future.
