Check Text (C-256578r991589_chk)
At the command line, run the following command:
# stat -c "%n permissions are %a and owned by %U:%G" /etc/ssh/*key
Expected result:
/etc/ssh/ssh_host_dsa_key permissions are 600 and owned by root:root
/etc/ssh/ssh_host_ecdsa_key permissions are 600 and owned by root:root
/etc/ssh/ssh_host_ed25519_key permissions are 600 and owned by root:root
/etc/ssh/ssh_host_rsa_key permissions are 600 and owned by root:root
If any key file listed is not owned by root or not group owned by root or does not have permissions of "0600", this is a finding.
Fix Text (F-60196r887407_fix)
At the command line, run the following commands for each returned file:
# chmod 600 <file>
# chown root:root <file>
