Processors
The following table lists the details of the processors supported by your OptiPlex 3090 Tower
Device Guard (DG) and Credential Guard (CG) are the security features that are available on Windows 10 Enterprise today.
Device Guard is a combination of enterprise-related hardware and software security features that, when configured together, will lock a device down so that it can only run trusted applications. If it is not a trusted application, it cannot run.
Credential Guard uses virtualization-based security to isolate secrets (credentials) so that only privileged system software can access them. Unauthorized access to these secrets can lead to credential theft attacks. Credential Guard prevents these attacks by protecting NTLM password hashes and Kerberos Ticket Granting Tickets.
