Check Text ( C-202r1_chk )
Analyze the system using the Security Configuration and Analysis snap-in. Expand the Security Configuration and Analysis tree view. Navigate to Local Policies -> Security Options. If the value for “System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing” is not set to “Enabled”, then this is a finding. The policy referenced configures the following registry value: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \System\CurrentControlSet\Control\Lsa\ Value Name: FIPSAlgorithmPolicy 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. Both the browser and web server must be configured to use TLS, or the browser will not be able to connect to a secure site.
