Check Text ( C-43271r1_chk )
Examine the rsyslog.conf file for any references to remote log hosts. # grep -v "^#" /etc/rsyslog* \| grep '@' # grep -v "^#" /etc/rsyslog.d/* \| grep '@' Destination locations beginning with an '@' represent log hosts. If the log host name is a local alias such as "loghost", consult the /etc/hosts or other name databases as necessary to obtain the canonical name or address for the log host. Determine if the host referenced is a log host documented using site-defined procedures. If an undocumented log host is referenced, this is a finding.
