Weight

Fix Recommendation

Configure OL 9 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. It is recommended to restart the system for the change of policies to fully take place.

Check Contents

Verify OL 9 cryptographic policies are not overridden.

Verify the configured policy matches the generated policy with the following command:

$ sudo update-crypto-policies --check && echo PASS
The configured policy matches the generated policy
PASS

If the last line is not "PASS", this is a finding.

List all of the crypto backends configured on the system with the following command:

$ ls -l /etc/crypto-policies/back-ends/
lrwxrwxrwx. 1 root root 40 Nov 13 16:29 bind.config -> /usr/share/crypto-policies/FIPS/bind.txt

If the paths do not point to the respective files under /usr/share/crypto-policies/FIPS path, this is a finding.

Note: nss.config should not be hyperlinked.
