Security threats in 2011 will be targeted, sophisticated and have the feel of something more like cyber-terrorism as the criminals get slicker in their attacks.
The warning comes from Websense, which has published its threat report for next year, pointing out that already the trend for blended web attacks has plagued 2010.
The web is the increasing route for criminal activity with recent examples of the Stuxnet and Aurora attacks showing the sophisticated nature of the way data is being targeted.
The conclusion of the Websense report, aside from the threats continuing to grow, is that legacy defences are now not longer adequate protection.
"The continued rise of organized cyber criminal gangs and the emergence of targeted advanced malware threats are the most concerning trend we've seen," said Dan Hubbard, CTO at Websense.
One of the other trends from this year that will carry on causing damage is the decision by cyber criminals to target social networking sites in their determination to steal data.
"With so many intertwined vectors, these threats demand a new approach to security that looks at both inbound and outbound content. To protect against today's blended and sophisticated threats, companies need to plug the space left by a scattershot spraying of point solutions," said David Redmond, vp of business development, product management and marketing at Websense.
