Careless and untrained employees will continue to be a very serious threat to organizations in 2010. Remember that insiders can be broken down into 3 categories: careless & untrained employees, employees that are duped or fall prey to social engineering type attacks, and malicious employees. The reason I think it is important to understand these categories of insiders is because protecting your network and critical/sensitive data is done very differently for each type. In a recent research report released by RSA, accidental disclosure of sensitive information occurs far more frequently than deliberate incidents.
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.
