This template policy setting allows you to configure policy settings in this zone consistent with a selected security level for example Low Medium Low Medium or High. If you enable this template policy setting and select a security level all values for individual settings in the zone will be overwritten by the standard template defaults. If you disable this template policy setting no security level is configured. If you do not configure this template policy setting no security level is configured. Note. Local Machine Zone Lockdown Security and Network Protocol Lockdown operate by comparing the settings in the active URL’s zone against those in the Locked-Down equivalent zone. If you select a security level for any zone (including selecting no security) the same change should be made to the Locked-Down equivalent. Note. It is recommended to configure template policy settings in one Group Policy object (GPO) and configure any related individual policy settings in a separate GPO. You can then use Group Policy management features (for example precedence inheritance or enforce) to apply individual settings to specific targets.
