About security zones

You can use security zones to specify how you want Microsoft Internet Explorer to download applications and files from different Web sites. Assigning a Web site to a zone lets you specify a level of security based on your level of confidence. Then, when you open or download content from a Web site, Internet Explorer uses the security settings you specified for the site’s zone. The zone of the current Web page appears on the Status Bar.

You can divide your Internet world into four security zones:

You can change the security level of each zone, and you can customize a zone’s security level by choosing the permission options you want. For example, if you’re confident that anything you download from your corporate intranet is safe, you can set the security level for your local intranet zone to low. That way, you can download files without receiving security alerts. Alternatively, for the Internet zone and the restricted sites zone, you may want to set the security levels to medium or high to see a warning before you open or download potentially damaging files or to prevent opening or downloading these files altogether.
