Description
If a remote log host is in use and it has not been justified and documented, sensitive information could be obtained by unauthorized users without the administrator’s knowledge. Satisfies: SRG-OS-000480-GPOS-00227, SRG-OS-000342-GPOS-00133, SRG-OS-000479-GPOS-00224

ℹ️ Check
Examine the "syslog.conf" file for any references to remote log hosts using command: # grep -v "^#" /etc/syslog.conf \| grep '@' @<loghost> Ask ISSO/SA for a list of valid remote syslog servers justified and documented using site-defined procedures. Destination locations beginning with "@" represent log hosts. If the log host name is a local alias, such as log host, 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 syslog host documented using site-defined procedures. If a loghost is not defined, not documented, or is commented out this is a finding.

✔️ Fix
Edit the /etc/syslog.conf file to include a documented and approved remote log host.
