URL Display Protections

Hackers commonly attempt to mislead users into thinking they are looking at information from a known and trusted source. A valuable hacking tool has been the ability to hide true URL information and domain names from users. Internet Explorer 7 contains two powerful visual tools to help prevent users from being duped: an Address Bar in every window and Internationalized Domain Name (IDN) support.
Address Bar in Every Window

With Internet Explorer 7, all browser windows require an Address Bar. Because hackers often have abused valid pop-up window actions to display windows with misleading graphics and data as a way to convince users to download or install their malware, the requirement of an Address Bar in each window will help ensure that users always know more about the true source of information they are seeing.

IDN Display Protections

Internet Explorer 7 natively delivers full IDN functionality and display protections. The Internet incorporates a global community, and browsers must be able to handle non-English characters and domain names. Operators of malicious Web sites have used international character display issues as a mechanism for phishing attacks against users and as a way to hide the true Web site domain name. The problem derives from international alphabets; many characters in certain languages (e.g., the letter “a” in English) can resemble entirely different characters in other languages (e.g., the letter “а” in Cyrillic). As a result, an individual with malicious intent may register a similar domain name to fool users into submitting their content to a false site. Previous versions of Internet Explorer did not have IDN support and thus were not vulnerable to this attack. Internet Explorer 7 not only delivers native IDN support but also provides extensive security mechanisms to protect users from attack. One of the core security features of IDN support in Internet Explorer 7 is the multiple language display in the Address Bar.

Internet Explorer 7 IDN rules force the display of the Punycode domain name format when multiple character sets are contained within a single domain name label. For example, the URL http://www.microsóft.com would be displayed in Punycode since it mixes both the French and English character sets in the same label portion. The address bar would display http://www.xn--microsft-03a.com, alerting the user and calling attention to the suspicious URL. The URL http://ŵŵŵ.microsoft.com would be displayed correctly because the language character sets are contained in separate labels.

Delete Browsing History for Better Protection of Privacy and Passwords

All Web browsers provide mechanisms to delete history information, clean the cache, erase automatically completed form history and clear the Start/Run history. The removal of this data requires deleting each set individually, and not all the necessary removal buttons are located on a single screen or within one application. Internet Explorer 7 provides a Delete Browsing History option that provides users with one-click cleanup to easily and instantly erase personal data. Delete Browsing History is especially valuable in shared-resource environments. Accessing online resources using a friend’s computer seems harmless enough, but the user then becomes reliant on the security of the friend’s system to protect his or her data. Likewise, in public environments such as libraries, schools and conference centers, computers may be used by hundreds of people and potentially expose personal data and history information to every one of those users. Delete Browsing History provides a simple mechanism to instantly erase information and eliminate any concern for data privacy on other systems. It is another way Microsoft is working proactively to deliver tools that improve user safety and data protection.

Parental Controls

Internet Explorer 7 in Windows Vista provides additional security and privacy mechanisms by utilizing a network layer filter component. Available to all Windows Vista applications, this network layer service allows parents to establish filter controls for objectionable content or define a specific set of allowable Web sites to browse. Internet Explorer 7 in Windows Vista works directly with the Parental Controls service to provide easy access to logging information and a single interface for managing settings. The Parental Controls service can also be set to block file downloads, offering another way to prevent malware from getting on a system. If Parental Controls are set to block downloads, Internet Explorer 7 in Windows Vista will automatically block the file unless the user is able to provide the appropriate administrative password. If Parental Controls are set to permit file downloads, all downloads will be logged for review at a later time. If a child attempts to access a page with mixed content — data contained both on and off the allowable list of Web sites — Internet Explorer 7 in Windows Vista will present the user with an Information Bar to request permission from a parent to approve the download. When the entire page is blocked, an error page is displayed that also provides a link allowing the child to request permission.

Improved Platform and Manageability

Web developers have expressed frustration with peculiarities in the behavior of Internet Explorer 6, especially in the areas of standards support. Application developers also want to take advantage of new Web capabilities but have been required to develop everything from the ground up to do so. And network administrators are always looking for better ways to manage large numbers of browser users.
With Internet Explorer 7, the browser architecture has been re-engineered to address compatibility and support a variety of rich end-user experiences. In early betas Microsoft demonstrated improved support for CSS as well as transparent PNG support. The latest release goes even further; Internet Explorer 7 is even more standards-compliant and makes Web and application development even easier. Yet, with all this new functionality, Internet Explorer 7 can continue to be centrally managed via Group Policy. The final release will include a new version of the Internet Explorer Administration Kit to enable more deployment options.

Improved CSS Support

CSS is a widely used standard for creating Web pages. Internet Explorer 7 prioritizes compliance to CSS standards by first implementing the features that developers have said are most important to them. As a result, in Internet Explorer 7, Microsoft has addressed some of the major inconsistencies that can cause Web developers problems producing rich, interactive Web pages. This includes fixing some positioning and layout issues related to the way Internet Explorer 6 handles

tags. (More information about these bugs can be found online at http://www.positioniseverything.net/explorer/peekaboo.html and http://www.positioniseverything.net/explorer/guillotine.html). Internet Explorer 7 will be shipped with improved CSS 2.1 support. Specific problems addressed by Internet Explorer 7 include the following:

Ability to hover on all elements
Fixed positioning
CSS 2 selectors
HTML 4.01 improvements
Windowless Select Element

Transparent PNG Support

Internet Explorer 7 also adds support for alpha-channel transparent PNGs. A PNG is a typographical file format that may include an indication of the exact degree of transparency a picture should have through a measurement called the alpha channel. With an alpha channel, designers can use special effects that were not previously supported. For instance, they can create Web page images that have shadows but do not obscure the background image behind them.

RSS Feed Platform

The Windows RSS Platform will be included as part of Internet Explorer 7. This platform provides rich functionality for downloading, storing and accessing feeds across the entire operating system, and will enable more users than ever to embrace RSS. This means that once a feed is subscribed to in one application, that subscription and associated content will be made available for all applications across the operating system. The days of having siloed RSS data in different applications are over.
The Windows RSS Platform provides this rich data layer through two primary components: the Common Feed List and the Common Data Store. The Common Feed List — accessible through either the Windows RSS Platform APIs or the file system — provides a common storage location for all subscribed-to sites. Any application can add or delete sites and can share information about the feeds, such as how subscriptions are organized in folders, for example. The Common Data Store — accessible through either the Windows RSS Platform APIs or the file system — handles downloading, storing and managing read and unread status of feed data.
Microsoft expects that the use of RSS enclosures will increase substantially over the coming months. The Common Data Store is an ideal tool for ensuring that the most updated content — such as text, calendar entries, pictures, podcasts and many other types of files — is delivered and accessible to anyone who subscribes to it. Further, because the platform does all the hard work of synching, parsing and storing RSS feeds, application developers will have a much easier time building applications that use RSS for their synching strategy. Microsoft believes that this platform technology will help enable a major increase in the number of applications that use RSS.
The primary initial users of the Windows RSS Platform will be technical enthusiasts who already use and subscribe to RSS as well as application developers who are looking for a new technology to help them share varied content between applications. As RSS adoption grows and Internet Explorer installations increase, Microsoft expects general users to begin using RSS ubiquitously, without even knowing it. Microsoft believes that this is a win-win situation for developers and end users.

OpenSearch

Internet Explorer 7 supports OpenSearch 1.1, the latest Creative Commons release of the standard from A9.com Inc., a subsidiary of Amazon.com Inc. that enables syndication formats such as RSS and Atom to be used in search applications. Further, the Toolbar Search Box in Internet Explorer 7 adopts OpenSearch extensions, permitting search engines to plug in to Internet Explorer simply by supporting OpenSearch.

Improved AJAX Support

Internet Explorer 7 improves the implementation of the XMLHTTP Request as a native Javascript object for rich AJAX-style applications. While Internet Explorer 6 handled XMLHTTP requests with an ActiveX control, Internet Explorer 7 exposes XMLHTTP natively. This improves syntactical compatibility across different browsers and allows for clients to configure and customize a security policy of their choice without compromising key AJAX scenarios.

Administration Improvements

With Internet Explorer 7, administrators have centralized control over settings via Active Directory^® Group Policy, which makes the browser more manageable. All previous and new features are manageable via Group Policy, including the Phishing Filter and all browser add-ons, to help administrators ensure that browser users comply with company standards. Further, fully customized Internet Explorer deployments will be possible with the enhanced Internet Explorer Administration Kit (IEAK 7). Customers can confirm compatibility of their key applications with Internet Explorer 7 using an updated version of the Application Compatibility Toolkit that was included in Windows XP Service Pack 2.
Even with all these improvements, Internet Explorer 7 is still a browser on which enterprises can depend. Internet Explorer will continue to be supported as part of the Windows platform, with continuous incident response support provided by the Microsoft Security Response Center. Further, there will be no change to Windows support life-cycle timelines with this new release, so administrators can be assured that Microsoft is standing behind the new release.

Conclusion

Internet Explorer 7 provides a safer, more personalized and more productive browsing experience for users and a richer, more compatible platform for developers and IT professionals. Microsoft encourages all Internet Explorer users running Windows XP SP2 or later to upgrade to Internet Explorer 7 today.
