Description
Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. The operating system must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated. This includes NIST FIPS-validated cryptography for the following: Provisioning digital signatures, generating cryptographic hashes, and to protect data requiring data-at-rest protections in accordance with applicable federal laws, Executive Orders, directives, policies, regulations, and standards. Satisfies: SRG-OS-000033-GPOS-00014, SRG-OS-000125-GPOS-00065, SRG-OS-000396-GPOS-00176, SRG-OS-000423-GPOS-00187, SRG-OS-000478-GPOS-00223

Check Text ( C-61971r926675_chk )
Verify that RHEL 9 is in FIPS mode with the following command: $ sudo fips-mode-setup --check FIPS mode is enabled. If FIPS mode is not enabled, this is a finding.

Fix Text (F-61895r926676_fix)
Configure the operating system to implement FIPS mode with the following command $ sudo fips-mode-setup --enable Reboot the system for the changes to take effect.
