What are the security zones?

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.

The following table describes the four Internet Explorer security zones.



The level of security set for the Internet zone is applied to all websites by default. The security level for this zone is set to Medium High (but you can change it to either Medium or High). The only websites for which this security setting is not used are those in the Local intranet zone or sites that you specifically entered into the Trusted or Restricted site zones.

Local intranet

The level of security set for the Local intranet zone is applied to websites and content that is stored on a corporate or business network. The security level for the Local intranet zone is set to Medium (but you can change it to any level).

Trusted sites

The level of security set for Trusted sites is applied to sites that you have specifically indicated to be ones that you trust not to damage your computer or information. The security level for Trusted sites is set to Medium (but you can change it to any level).

Restricted sites

The level of security set for Restricted sites is applied to sites that might potentially damage your computer or your information. Adding sites to the Restricted zone does not block them, but it prevents them from using scripting or any active content. The security level for Restricted sites is set to High and can't be changed.
