The result is that all members of "Tier0-Users" and "Tier0-Computers" are allowed to log on to Tier 0 systems only. and finally the "T0 Access (Computer)" GPO is applied to Tier 0 systems only removing all "Deny" restrictions for those targets:.

followed by the "T0 Initial Isolation (Computer)" GPO effectively blocking all members of both the "Tier0-Users" and "Tier0-Computers" security groups from logging on to any Windows systems.

The Default Domain Controllers Policy is processed first.

Although this would protect domain admin credentials as much as possible, it is obviously not a great idea. If the link order is wrong, we block domain admins from logging on to any Windows system in the domain including domain controllers. NOTE: The link order of the two GPOs is extremely important, so you want to test this in a non-production environment first. Even linking both GPOs to the domain node has no impact yet. So far we did not add any members to the "Tier0-Users" and "Tier0-Computers" security groups.

The resulting GPO "T0 Access (Computer)" looks like this: The resulting GPO "T0 Initial Isolation (Computer)" looks like this:

"Deny log on through Terminal Services" is defined but has no one added.

"Deny log on locally" is defined but has no one added.

"Deny log on as a service" is defined but has no one added."Deny log on as a batch job" is defined but has no one added."Deny access to this computer from the network" is defined but has no one added.The "T0 Access (Computer)" GPO defines the following local security policy and targets all Windows systems in Tier 0 with security filtering set to "Tier0-Computers":."Deny log on through Terminal Services" for both the security groups "Tier0-Users" and "Tier0-Computers"."Deny log on locally" for both the security groups "Tier0-Users" and "Tier0-Computers"."Deny log on as a service" for both the security groups "Tier0-Users" and "Tier0-Computers"."Deny log on as a batch job" for both the security groups "Tier0-Users" and "Tier0-Computers"."Deny access to this computer from the network" for both the security groups "Tier0-Users" and "Tier0-Computers".The "T0 Initial Isolation (Computer)" GPO defines the following local security and targets all Windows systems in the domain with security filtering set to "Authenticated Users":.We need at least two GPOs which both are linked to the domain node: Permissions to create Group Policy objects on the domain level.At the very least all domain controllers must be added to this group Its members will be all highly privileged computers accounts which must not connect to systems other than Tier 0. An initially empty global security group "Tier0-Computers".At the very least all domain admins must be added to this group Its members will be all highly privileged user accounts which must not exposed on systems other than Tier 0. An initially empty global security group "Tier0-Users".The target audience are organizations which have not yet restrictions for the movement of domain admins in their environment. Implementing complete administrative tiering would require additional steps like creating a new structure of Organizational Units (OUs) in Active Directory to securely host Tier 0 assets, apply restricted delegations and security baselines from the Microsoft Security Compliance Toolkit (SCT). Enforce the use of dedicated administrative workstations at least for domain controller access.Prevent exposure of highly privileged domain admin accounts on lower privileged systems.The approach outlined in this article has the following goals: If you are not familiar with Microsoft's administrative tiering model, a great starting point would be this article and this one.

In this post, I am going to show you how to use a minimal set of Group Policy objects to isolate domain admins and domain controllers and other Tier 0 assets. Hello everyone, my name is Daniel Metzger and I am a Senior Premier Field Engineer for Secure Infrastructure based in Switzerland.
