Check Text (C-271778r1092046_chk)
Verify that OL 9 configures permissions 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" permissions are not "0600", this is a finding.
Fix Text (F-75735r1092045_fix)
Configure the "/etc/ssh/sshd_config" permissions to be "0600" with the following command:
$ sudo chmod 0600 /etc/ssh/sshd_config
