Microsoft releases IE8 beta 2

On Wednesday in the US, Microsoft released the second public beta for Internet Explorer 8.

The user interface hasn't changed much since Internet Explorer 8 Beta 1, except to add a Security pull-down menu between Page and Tools on the main toolbar. In addition to blocking phishing sites, IE8 now highlights the main domain of any Web site you visit. Thus if you think you are on eBay's site and something other than ebay.com is highlighted, chances are you are on the wrong Web site.

IE8 also contains a cross-site scripting filter, one of the first in a mainstream browser. Cross-site scripting allows an attacker to execute script on a user's browser without them knowing.

When the IE8 filter finds a Web page with a cross-site scripting request, it changes the content on the page with a notice. Users are not presented with an option; IE simply blocks the malicious script from executing and then displays the rest of the page.

In another feature, known as InPrivate, Microsoft allows the user to suspend caching functions while you surf. The scenarios for using InPrivate include when you're using someone else's computer, like for instance, when you need to buy a gift for a loved one without ruining the surprise, or when you're at an Internet kiosk and don't want the next person to know which Web site you visited.

While you can currently clear the browser cache with a mouse click, it's an all-or-nothing action. InPrivate temporarily suspends the automatic caching functions, allowing you to keep the rest of your browsing history intact. Apple Safari has offered this feature for a while, but Mozilla Firefox does not.

IE8 Beta 1 has already introduced several behind-the-scenes security changes. For example, ActiveX components will be installed per user, which eliminates the need for everyone to have administrator privileges.

In addition, you must acknowledge or opt in for the component to run, eliminating drive-by downloads. Components will be per site and will only be available from the site of origin. Finally, site developers can request killbits from Microsoft which can be sent via Windows Update to terminate risky or outdated components.

Also, IE8 Beta 1 included Microsoft's own brand of malware protection. Earlier this year, Opera added Haute Secure malware protection, and Mozilla enhanced its Google and StopBadware malware protection in Firefox 3.
