| Description | ||||
| This setting ensures 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. Note: A different registry location is needed when systems are managed by Intune versus GPO. | ||||

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\ (For GPO-managed systems)
Or
Registry Path: \SOFTWARE\Microsoft\PolicyManager\current\device\Cryptography!AllowFipsAlgorithmPolicy_ProviderSet (For Intune-managed systems)
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.
Fix Text (F-56869r1210240_fix)
For GPO-managed systems:
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".
For Intune-managed systems:
Set the Intune System Cryptography Policy to use FIPS-compliant algorithms for encryption, hashing, and signing.
