In this article “Both the number and volume of distributed denial-of-service attacks are increasing, according to new reports from DDoS mitigation companies Prolexic and Arbor Networks.

During the fourth quarter of last year, Prolexic detected 45% more DDoS attacks compared to the similar period of 2010 and more than twice the number of attacks observed during the third quarter of 2011.

There’s a trend toward a shorter attack duration, but a bigger packet-per-second attack volume, said Paul Sop, Prolexic’s chief technology officer.

The average attack bandwidth registered in the fourth quarter of 2011 was 5.2G bps (bits per second), 148% higher than what it was during the third quarter. The year over year increase for attack bandwidth in 2011 was 136%.
