Processors NOTE: Global Standard Products (GSP) are a subset of Dell's relationship products that are managed for availability and synchronized transitions on a worldwide basis. They ensure the same platform is available for purchase globally. This allows customers to reduce the number of configurations managed on a worldwide basis, thereby reducing their costs.

9 They also enable companies to implement global IT standards by locking in specific product configurations worldwide. Device Guard (DG) and Credential Guard (CG) are the new security features that are only available on Windows Enterprise operating system today. Device Guard is a combination of enterprise-related hardware and software security features. When you configure together, it locks a device down so that it can only run trusted applications. Credential Guard uses virtualization- based security to isolate secrets (credentials) so that only privileged system software can access them.

10 Unauthorized access to these secrets can lead to credential theft attacks. Credential Guard prevents these attacks by protecting NT LAN Manager (NTLM) password hashes and Kerberos Ticket Granting Tickets. NOTE: Processor numbers are not a measure of performance. Processor availability is subject to change and may vary by region/country. Table 3.
