The following table describes the four Internet Explorer security zones.
Internet security zone settings are applied to all websites except those in the Local intranet, Trusted, or Restricted site security zones.
Local intranet security zone settings are applied to websites and content stored on a corporate or business network. You can define sites in this zone or add sites to this zone by clicking the Sites button.
Trusted sites security zone settings are applied to websites that you trust not to damage your computer or information. You can add sites to this zone by clicking the Sites button.
Restricted sites security zone settings are applied to websites that you think might damage your computer or your information. Adding sites to the Restricted zone doesn't block them, but it prevents them from running programs or any active content. You can add sites to this zone by clicking the Sites button.
