In 2009, Malware was listed as a 'steady threat' and the 2nd highest ranked threat to organizations. I underestimated the dramatic increase in malware in 2009. Due to that increase and the number of organizations that are affected each day by malware, I have elevated it to the #1 position. This is a bit controversial since most security experts would list insiders as the top threat, but I believe in 2010 more organizations will be negatively affected by malware than by malicious insiders.
We got such a great response to a guest contribution by Perimeter CTO Kevin Prince over at our Network Security Edge site about his views on the top threats for this year that we asked him if we could use the information as the basis of this quick presentation.
You'll get a lot of useful info by clicking through these slides, but we strongly encourage you to check out Prince's full analysis of 2009's trends and his thoughts on the threats, both growing and persistent, facing your network.
