Would you believe that your everyday users could pose the biggest security risk to your company? I know, I know, that's impossible. People never share too much information or put convenience over security-- ever.

But according to this security report from <a href="http://www.sophos.com/sophos/docs/eng/papers/sophos-security-threat-report-jul-2009-na-wpus.pdf">SOPHOS</a> , users who post on Twitter, Facebook, MySpace, and other networking sites while on the job can pose the greatest risk to your company's digital security. Not surprising, a good portion of users have been spammed or scammed while accessing these sites-- they're graphed via pie chart in the report linked above.

Possibly scarier than that is the amount of &quot;I don't know&quot; responses received-- yikes!
