In part III of this installment, I’ll continue describing some of the new and updated features found in IE 7. The security zones in Internet Explorer 7 have been changed to make the browser more resistant to attacks. The browser still includes the four security zones: Internet, Intranet, Trusted Sites and Restricted sites, but you will see some subtle changes. For example, the default level for the Trusted Sites zone is now set to Medium. In IE 6, it was set to Low.
To prevent against zone-spoofing attacks, the Intranet zone is now disabled if IE 7 determines that the computer is not connected to a domain. All sites are then treated as one in the more secure Internet zone.
Note: In a zone-spoofing attack, attackers can fool the Web browser into thinking that it is a trusted site.
Fixing your Security Settings
One of the really handy new features of Internet Explorer 7 is that it will alert you when your browser’s security settings may be putting you at risk by presenting an Information Bar. You can quickly and easily reset the security settings by clicking the Information Bar and selecting the Fix Settings for Me.
When you select the Fix Settings for Me option from the Information Bar, a prompt will appear asking you if you want to fix your settings. Click the Fix Settings button to restore your Internet Explorer security settings to their defaults.
No Add-ons Mode
If you are experiencing odd behavior with your browser, such as hanging or crashing, it could be due to an add-on. The best way to determine if an add-on is the culprit, is to start Internet Explorer with no add-ons.
To start IE 7 in ‘No Add-ons Mode’: click Start, All Programs, Accessories, System Tools and click Internet Explorer (No add-ons). When started in this mode, only the critical system add-ons are enabled.
