Security zones: adding or removing websites

The information in this Help topic applies to Windows Internet Explorer 7 and Windows Internet Explorer 8.

Internet Explorer assigns all websites to one of four security zones: Internet, Local intranet, Trusted sites, or Restricted sites. The zone to which a website is assigned specifies the security settings that are used for that site. You can choose which websites to assign to the Intranet, Trusted, or Restricted zones. By adding a website to a specific zone, you can control the level of security used on that site. For example, if you have a list of websites that you visit and you completely trust those sites, add those sites to the Trusted zone.

For more information about security zones, see Change Internet Explorer Security Settings.
