4.2.1.2 Ensure logging is configured (Not Scored)
Profile Applicability
Level 1 - Server Level 1 - Workstation
Description
The /etc/rsyslog.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 rsyslog (e.g., successful and failed su attempts, failed login attempts, root login attempts, etc.).
Audit
Review the contents of the /etc/rsyslog.conf
file to ensure appropriate logging is set. In addition, run the following command and verify that the log files are logging information:
# ls -l /var/log/
Remediation
Edit the following lines in the /etc/rsyslog.conf file as appropriate for your environment:
*.emerg :omusrmsg:* mail.* -/var/log/mail mail.info -/var/log/mail.info mail.warning -/var/log/mail.warn mail.err /var/log/mail.err news.crit -/var/log/news/news.crit news.err -/var/log/news/news.err news.notice -/var/log/news/news.notice *.=warning;*.=err -/var/log/warn *.crit /var/log/warn *.*;mail.none;news.none -/var/log/messages local0,local1.* -/var/log/localmessages local2,local3.* -/var/log/localmessages local4,local5.* -/var/log/localmessages local6,local7.* -/var/log/localmessages
Run the following command to restart rsyslogd
:
# pkill -HUP rsyslogd
