Description

Centralized cryptographic policies simplify applying secure ciphers across an operating system and the applications that run on that operating system. Using weak or untested encryption algorithms undermines the purposes of using encryption to protect data. Satisfies: SRG-OS-000396-GPOS-00176, SRG-OS-000393-GPOS-00173, SRG-OS-000394-GPOS-00174

ℹ️ Check

Verify OL 8 cryptographic policies are not overridden. Verify the configured policy matches the generated policy with the following command: $ sudo update-crypto-policies --is-applied The configured policy is applied If the returned message does not match the above, this is a finding.

✔️ Fix

Configure OL 8 to correctly implement the systemwide cryptographic policies by reinstalling the crypto-policies package contents. Reinstall crypto-policies with the following command: $ sudo dnf -y reinstall crypto-policies Set the crypto-policy to FIPS with the following command: $ sudo update-crypto-policies --set FIPS Setting system policy to FIPS Note: Systemwide crypto policies are applied on application startup. Restart the system for the changs to take place.
