4.2.2.2 Ensure logging is configured (Not Scored)
Profile Applicability
- Level 1 - Server
- Level 1 - Workstation
Description
The /etc/syslog-ng/syslog-ng.conf file specifies rules for logging and which files are to be used to log certain classes of messages.
Rationale
A great deal of important security-related information is sent via syslog-ng (e.g., successful and failed su attempts, failed login attempts, root login attempts, etc.).
Audit Procedure
Review the contents of the /etc/syslog-ng/syslog-ng.conf file to ensure appropriate logging is set. In addition, run the following command and ensure that the log files are logging information:
ls -l /var/log/
Expected Result
Log files should exist and contain recent entries for all configured facilities.
Remediation
Edit the log lines in the /etc/syslog-ng/syslog-ng.conf file as appropriate for your environment:
log { source(src); source(chroots); filter(f_console); destination(console); };
log { source(src); source(chroots); filter(f_console); destination(xconsole); };
log { source(src); source(chroots); filter(f_newscrit); destination(newscrit); };
log { source(src); source(chroots); filter(f_newserr); destination(newserr); };
log { source(src); source(chroots); filter(f_newsnotice); destination(newsnotice); };
log { source(src); source(chroots); filter(f_mailinfo); destination(mailinfo); };
log { source(src); source(chroots); filter(f_mailwarn); destination(mailwarn); };
log { source(src); source(chroots); filter(f_mailerr); destination(mailerr); };
log { source(src); source(chroots); filter(f_mail); destination(mail); };
log { source(src); source(chroots); filter(f_acpid); destination(acpid); flags(final); };
log { source(src); source(chroots); filter(f_acpid_full); destination(devnull); flags(final); };
log { source(src); source(chroots); filter(f_acpid_old); destination(acpid); flags(final); };
log { source(src); source(chroots); filter(f_netmgm); destination(netmgm); flags(final); };
log { source(src); source(chroots); filter(f_local); destination(localmessages); };
log { source(src); source(chroots); filter(f_messages); destination(messages); };
log { source(src); source(chroots); filter(f_iptables); destination(firewall); };
log { source(src); source(chroots); filter(f_warn); destination(warn); };
Run the following command to reload the syslog-ng configuration:
pkill -HUP syslog-ng
Default Value
Basic logging is configured by default.
