SV-78117r1_rule Systems must at least attempt device authentication using certificates.

Vulnerability discussion

Using certificates to authenticate devices to the domain provides increased security over passwords. By default systems will attempt to authenticate using certificates and fall back to passwords if the domain controller does not support certificates for devices. This may also be configured to always use certificates for device authentication.

Check content

This requirement is applicable to domain-joined systems, for standalone systems this is NA. The default behavior for "Support device authentication using certificate" is "Automatic". If the registry value name below does not exist, this is not a finding. If it exists and is configured with a value of "1", this is not a finding. If it exists and is configured with a value of "0", this is a finding. Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\Kerberos\Parameters\ Value Name: DevicePKInitEnabled Value Type: REG_DWORD Value: 1 (or if the Value Name does not exist)

Fix text

This requirement is applicable to domain-joined systems, for standalone systems this is NA. The default behavior for "Support device authentication using certificate" is "Automatic". If this needs to be corrected, configured the policy value for Computer Configuration >> Administrative Templates >> System >> Kerberos >> "Support device authentication using certificate" to "Not Configured or "Enabled" with either option selected in "Device authentication behavior using certificate:".

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
