Fix Recommendation

Configure the AlmaLinux OS 9 SSH daemon to use systemwide crypto policies by running the following commands:

$ sudo dnf reinstall openssh-server

Check Contents

Verify that systemwide crypto policies are in effect with the following command:

$ sudo /usr/sbin/sshd -dd 2>&1 | awk '/filename/ {print $4}' | tr -d '\r' | tr '\n' ' ' | xargs sudo grep -iH '^\s*include'

/etc/ssh/sshd_config:Include /etc/ssh/sshd_config.d/*.conf
/etc/ssh/sshd_config.d/50-redhat.conf:Include /etc/crypto-policies/back-ends/opensshserver.config

If "Include /etc/ssh/sshd_config.d/*.conf" or "Include /etc/crypto-policies/back-ends/opensshserver.config" are not included in the system sshd config or the file /etc/ssh/sshd_config.d/50-redhat.conf is missing, this is a finding.
