Title

Supported authentication schemes must be configured. (Cat II impact)

Discussion

This setting specifies which HTTP authentication schemes are supported. The policy can be configured by using these values: "basic", "digest", "ntlm", and "negotiate". Separate multiple values with commas. If this policy is not configured, all four schemes are used.

Check Content

The policy value for "Computer Configuration/Administrative Templates/Microsoft Edge/HTTP authentication/Supported authentication schemes" must be set to "ntlm,negotiate". Use the Windows Registry Editor to navigate to the following key: HKLM\SOFTWARE\Policies\Microsoft\Edge If the value for "AuthSchemes" is not set to "REG_SZ = ntlm,negotiate", this is a finding.

Fix Text

Set the policy value for "Computer Configuration/Administrative Templates/Microsoft Edge/HTTP authentication/Supported authentication schemes" to "ntlm,negotiate".
