Microsoft® Internet Explorer 4.0 and later versions provide users with a set of templates that they can use to determine the level of security they want for a particular URL security zone. For more information on URL security zones, see the About URL Security Zones section of URL Security Zones Overview.
The URL security zone templates provide different levels of security. The High template contains settings that provide the highest level of security by restricting Web sites from doing potentially damaging operations. The Low template, on the other hand, contains the settings that provide the lowest level of security, allowing Web sites more access to the user's system.
When URL security zones was introduced in Internet Explorer 4.0, there were three default templates (High, Medium, and Low). Beginning with Internet Explorer 5, a fourth template, Medium-Low, was added.
The following list contains links to the templates that are used by Internet Explorer.
Currently, the settings for each of the default templates are stored in the registry. For more information about the registry keys used, see the Registry Keys section below.
The High template is used for URL security zones that contain Web sites that could cause damage to you computer or data. The settings used by this template will restrict sites from doing potentially damaging operations. By default, the Restricted sites zone uses this template.
The following table contains the URL actions whose URL policy was changed in Internet Explorer 5. Next to each URL action is the the URL policy assigned by the Internet Explorer 4.0 version of this template.
| URL action | URL policy |
|---|---|
| URLACTION_HTML_SUBMIT_FORMS | URLPOLICY_DISALLOW |
| URLACTION_SHELL_MOVE_OR_COPY | URLPOLICY_DISALLOW |
The Medium template is used for URL security zones that contain Web sites that are neither trusted nor untrusted. By default, the Internet zone uses this template.
The following table contains the URL actions whose URL policy has changed in Internet Explorer 5. Next to each URL action is the the URL policy assigned by the Internet Explorer 4.0 version of this template.
| URL action | URL policy |
|---|---|
| URLACTION_ACTIVEX_OVERRIDE_OBJECT_SAFETY | URLPOLICY_QUERY |
| URLACTION_SHELL_FILE_DOWNLOAD | URLPOLICY_QUERY |
| URLACTION_SHELL_MOVE_OR_COPY | URLPOLICY_QUERY |
The Medium-Low template is used for URL security zones that contain Web sites that are unlikely to cause damage to your computer or data. By default, the Intranet zone uses this template.
The Low template is used for URL security zones that contain Web sites that are fully trusted by the user. By default, the Trusted sites zone uses this template.
The following table contains the URL actions whose URL policy has changed in Internet Explorer 5. Next to each URL action is the the URL policy assigned by the Internet Explorer 4.0 version of this template.
| URL action | URL policy |
|---|---|
| URLACTION_SHELL_FILE_DOWNLOAD | URLPOLICY_QUERY |
| URLACTION_SHELL_VERB | URLPOLICY_QUERY |
Currently, the settings for each template are stored in the registry under the following keys:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
Internet Settings\TemplatePolicies
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
Internet Settings\TemplatePolicies
The information under these registry keys should be used for reference only. Future versions of Internet Explorer may not use the registry to store template information, so developers should not directly manipulate the registry.
