Spam levels to rocket in 2007

Stopping spam will become increasingly important as e-mail attacks reach an unprecedented level in 2007, security firm Postini warned last week.

Spam levels shot up 147% last year and accounted for 94% of all e-mails in December, according to Postini.

The firm said there were no signs of a let up in spam in 2007, highlighting a recent survey that showed more than 90% of business communications professionals expected spam to increase in 2007.

Botnet attacks - whereby a number of computers forward spam and viruses to other computers via the internet - are also expected to rise this year with the increasing number of viruses and worms attempting to hijack ever larger networks of personal computers, Postini warned.

"2007 clearly presents an increasingly challenging communications security and compliance landscape for businesses to navigate," Daniel Druker, executive vice president at Postini, commented.

Communications compliance is another key issue, Postini said. More than half of those polled in the firm's survey said their top priority was to develop a strategy to comply with regulations for e-discovery in connection with possible litigation and in response to new legislation.

2007 will be an explosive year for communications compliance initiatives, the firm predicted.
