The system must be configured to use FIPS-compliant algorithms for encryption, hashing, and signing.

STIG ID: WN11-SO-000230 |  SRG: SRG-OS-000478-GPOS-00223 |  Severity: medium |  CCI:  | Vulnerability Id: V-253466

Vulnerability Discussion

This setting ensures that the system uses algorithms that are FIPS-compliant for encryption, hashing, and signing. FIPS-compliant algorithms meet specific standards established by the U.S. Government and must be the algorithms used for all OS encryption functions.

Check

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> Security Options >> "System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing" to "Enabled".

Fix

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: \SYSTEM\CurrentControlSet\Control\Lsa\FIPSAlgorithmPolicy\

Value Name: Enabled

Value Type: REG_DWORD
Value: 1

Warning: Clients with this setting enabled will not be able to communicate via digitally encrypted or signed protocols with servers that do not support these algorithms.
