Microsoft Internet Explorer Security Strikes Back
Microsoft Internet Explorer 8 Beta 2 security builds on the Phishing Filter of IE 7 and thwarts cross-site scripting.Microsoft Internet Explorer 8 Beta 2 will put a bull's-eye on malicious sites courtesy of the new SmartScreen Filter. The feature, revealed July 2, is an answer to the blacklisting features built into Firefox 3 and Opera 9.5, and builds on the Phishing Filter introduced in IE 7 with, among other things, anti-malware support and new heuristic detection capabilities to block known bad sites. Security has been a key battleground between Microsoft's Internet Explorer, Mozilla's Firefox and other browsers. In addition to blocking bad sites, the filter also protects users who click on a link leading to a download on a rogue site by interrupting the download with a warning, according to Microsoft.
When it comes to thwarting XSS (cross-site scripting), Microsoft has added a filter that uses a heuristics-based approach to sanitize injected scripts.
