Verify that OL 9 monitors all remote access methods.

Check that remote access methods are being logged by running the following command:

$ grep -rE '(auth.\*|authpriv.\*|daemon.\*)' /etc/rsyslog.conf
authpriv.* /var/log/secure

If "auth.*", "authpriv.*" or "daemon.*" are not configured to be logged, this is a finding.
