The BrowserShield Project: Vulnerability-Driven Filtering of Dynamic HTML
According to this eWeek article, researchers at Microsoft have completed work on a security project called "BrowserShield" that promises to allow IE to intercept and remove, on the fly, malicious code hidden on Web pages.
This can provide another layer of security, even on unpatched browsers," Wang said in an interview with eWEEK. "If a patch isn't available, a BrowserShield-enabled tool bar can be used to clean pages hosting malicious content.
From what I have read, Browsershield seems to be working like a security buffer that loads each pages in a secure environment, scans and removes malicious code from them, and then send the clean content over to the browser to be viewed by the user. I know that most of you guys love to hate Microsoft, but for once, this project really looks promising.
