WPAW-00-000600 - All high-value IT resources must be assigned to a specific administrative tier to separate highly sensitive resources from less sensitive resources.

Information

Note: The Microsoft Tier 0-2 AD administrative tier model (https://docs.microsoft.com/en-us/windows-server/identity/securing-privileged-access/securing-privileged-access-reference-material#ADATM_BM) is an example.

A key security construct of a PAW is to separate high-value IT resources into specific trust levels so that if a device at one trust level is compromised the risk of compromise of more critical IT resources at a different tier is reduced. This architecture protects IT resources in a tier from threats from higher-risk tiers. Isolating administrative accounts by forcing them to operate only within their assigned trust zone implements the concept of containment of security risks and adversaries within a specific zone.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Set up an administrative tier model for the domain (for example, the Microsoft-recommended Tier 0-2 AD administrative tier model). (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.)

Using the list of site designated high-value IT resources (see check WPAW-00-000200), indicate on the list the administrative Tier level the resource is assigned to. (Note: The updated list will be used in check WPAW-00-000400.)

In Active Directory, assign all high-value IT resources to the appropriate Organizational Units (for example):

- Admin\Tier 0\Devices
- Admin\Tier 1\Devices
- Admin\Tier 2\Devices
