Use lockdown mode

Lockdown mode is a feature that you can use to secure published sites. When lockdown mode is turned on, fine-grain permissions for the limited access permission level are reduced. The following table details the default permissions of the limited access permission level and the reduced permissions when lockdown mode is turned on.

Lockdown mode is applied to sites under the following circumstances:

• The Stsadm.exe command-line tool is used to turn lockdown mode on.
• The Publishing Portal site template is applied to the site collection. By default, lockdown mode is turned on when this template is applied.

Consider using lockdown mode on published sites if greater security on these sites is a requirement. Additionally, if you applied the Publishing Portal site template, determine if lockdown mode is the desired configuration for these sites. If not, use the Stsadm.exe command-line tool to turn off lockdown mode.

The following table lists the Stsadm commands related to using lockdown mode.
