Discussion

Service configuration files enable or disable features of their respective services, which if configured incorrectly, can lead to insecure and vulnerable configurations. Therefore, service configuration files must be owned by the correct group to prevent unauthorized changes.

Check Content

Verify that OL 9 configures ownership of the "/etc/ssh/sshd_config" file with the following command:

$ ls -al /etc/ssh/sshd_config
rw-------. 1 root root 3669 Feb 22 11:34 /etc/ssh/sshd_config

If the "/etc/ssh/sshd_config" file does not have an owner of "root", this is a finding.

Fix Text

Configure the "/etc/ssh/sshd_config" file to be owned by root with the following command:

$ sudo chown root /etc/ssh/sshd_config
