 Since domain-joined devices also use shared secrets for authentication, attackers can steal those secrets as well. By deploying device certificates with Credential Guard, the private key can be protected. Then authentication policies can require that users sign on devices which authenticate using those certificates. This prevents shared secrets on stolen from the device to be used with stolen user credentials to sign on as the user.
 
 Domain-joined device certificate authentication has the following requirements:
--   Devices' accounts are in Windows Server 2012 DFL or higher domains.

 #### Restricting user sign on

+So we now have the following:

 -   Created a special certificate issuance policy to identify devices which meet the deployment criteria required for the user to be able to sign on
 -   Mapped that policy to a universal security group or claim
 -   Provided a way for domain controllers to get the device authorization data during user sign on using Kerberos armoring-   
 so what is left to do is configuring the access check on the domain controllers. This is done with authentication policies.
