Deploy Office for Mac 2011 security preferences
You can deploy the privacy options, document protection settings, and security settings for macros by using Workgroup Manager or as part of a .pkg file. For more information about how to deploy security preferences, see Deploy Office for Mac 2011 preferences.
There are no administrative settings that allow you to enforce security preferences that you specify. Even if you set and deploy security preferences, users can change these preferences at a later time. Therefore, if you are deploying security settings as part of your organization's policy, you must educate your users about the risks associated with changing default settings.
