The largest Internet security threats now arrive through malicious web pages or e-mail attachments. Security is not about SYN packets, it is about data: the software attack surface that attacker-controlled software can get ahold of.

Google Chrome has overtaken Safari as the #3 browser and will have a stable release for Mac and Linux. Microsoft Office 2010 will include Protected View for viewing files from the Internet.
