Pete LePage works as a PM on the Internet Explorer team working with developer security. He stopped by the studio today to give us some tips as surfers, as well as a few tips for developers, on some of the things that can help prevent security threats. In 2008 a study showed that about 70% of attacks on web sites were from cross-site scripting. Pete goes through three security topics that every developer should know about. They include tips for cross-site scripting defenses, HTML sanitization, and JSON sanitization. You can find out more about these tips here.
