Verify that the SUSE operating system must off-load rsyslog messages for networked systems in real time and off-load standalone systems at least weekly. For stand-alone hosts, verify with the System Administrator that the log files are off-loaded at least weekly. For networked systems, check that rsyslog is sending log messages to a remote server with the following command: # sudo grep "\.\" /etc/rsyslog.conf \| grep "@" \| grep -v "^#" .;mail.none;news.none @192.168.1.101:514 If any active message labels in the file do not have a line to send log messages to a remote server, this is a finding.

Verify that the SUSE operating system must off-load rsyslog messages for networked systems in real time and off-load standalone systems at least weekly.

For stand-alone hosts, verify with the System Administrator that the log files are off-loaded at least weekly.

For networked systems, check that rsyslog is sending log messages to a remote server with the following command:

# sudo grep "\*.\*" /etc/rsyslog.conf | grep "@" | grep -v "^#"

*.*;mail.none;news.none @192.168.1.101:514

If any active message labels in the file do not have a line to send log messages to a remote server, this is a finding.

Fix Text (F-84125r1_fix)
Configure the SUSE operating system to off-load rsyslog messages for networked systems in real time. For stand-alone systems establish a procedure to off-load log messages at least once a week. For networked systems add a "@[Log_Server_IP_Address]" option to every active message label in "/etc/rsyslog.conf" that does not have one. Some examples are listed below: .;mail.none;news.none -/var/log/messages .;mail.none;news.none @192.168.1.101:514 An additional option is to capture all of the log messages and send them to a remote log host: . @@loghost:514
