| Set up an administrative tier model for the domain (for example, the Microsoft recommended Tier 0-2 AD administrative tier model). |
Note: Details of the Tier model are found at https://docs.microsoft.com/en-us/windows-server/identity/securing-privileged-access/securing-privileged-access-reference-material#ADATM_BM.
Set up an Admin Organizational Unit (OU) Framework to host site PAWs. (Recommend the Microsoft PAW scripts be used to set up the PAW OU and group framework. They can be downloaded at http://aka.ms/PAWmedia.)
- Admin\Tier 0\Accounts
- Admin\Tier 1\Accounts
- Admin\Tier 2\Accounts
- Admin\Tier 0\Groups
- Admin\Tier 1\Groups
- Admin\Tier 2\Groups
- Admin\Tier 0\Devices
- Admin\Tier 1\Devices
- Admin\Tier 2\Devices
Note: If using the Microsoft scripts, after running the scripts, PAW Users Tier 0, PAW Users Tier 1, and PAW Users Tier 2 groups may need to be created under Admin/Tier 0/Groups, Admin/Tier 1/Groups, and Admin/Tier 2/Groups, respectively.
Set up administrative accounts for each assigned administrator for high-value IT resources.
Based on the list of high-value IT resources with assigned administrative tier level, move Tier 0-2 administrative accounts to the appropriate Organizational Units and add the appropriate members to the relevant groups. Make sure each account and group has been assigned to one and only one tier.
