Description
Digest authentication is not as strong as other options and may be subject to man-in-the-middle attacks. Disallowing Digest authentication will reduce this potential.
ℹ️ Check
If the following registry value does not exist or is not configured as specified, this is a finding:
Registry Hive: HKEY_LOCAL_MACHINE
Registry Path: \SOFTWARE\Policies\Microsoft\Windows\WinRM\Client\
Value Name: AllowDigest
Type: REG_DWORD
Value: 0x00000000 (0)
✔️ Fix
Configure the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> Windows Remote Management (WinRM) >> WinRM Client >> Disallow Digest authentication to "Enabled".
