Fix Recommendation

Configure the AlmaLinux OS 9 OpenSSL library to use the system cryptographic policy.

Edit the "/etc/pki/tls/openssl.cnf" and add or modify the following line:

.include = /etc/crypto-policies/back-ends/opensslcnf.config

Check Contents

Verify that AlmaLinux OS 9 OpenSSL library is configured to use only ciphers employing FIPS 140-3 approved algorithms with the following command:

$ grep -i opensslcnf.config /etc/pki/tls/openssl.cnf

.include = /etc/crypto-policies/back-ends/opensslcnf.config

If the "opensslcnf.config" is not defined in the "/etc/pki/tls/openssl.cnf" file, this is a finding.
