According to a recent report from Kaspersky Lab, distributed denial of service attacks increased in power during the past year.

"The most powerful attack of the year, which came in the second half, clocked in at 600Mbit/sec, while the average strength for the six months was 110Mbit/sec, an increase of 57 percent from the first half," writes The Inquirer's Dave Neal.

"The firm said that online trade is most often targeted, with 25 percent of attacks," Neal writes. "By comparison, government web sites, which are often attacked by Anonymous, account for just two percent of attacks."
