Profile Applicability

Description
The /etc/rsyslog.conf and /etc/rsyslog.d/*.conf files 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 Procedure
Review the contents of the /etc/rsyslog.conf and /etc/rsyslog.d/*.conf files 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/
Expected Result
Log files should exist and contain recent entries for all configured facilities.
Remediation
Edit the following lines in the /etc/rsyslog.conf and /etc/rsyslog.d/*.conf files 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 reload the rsyslogd configuration:
pkill -HUP rsyslogd
Default Value
Basic logging is configured by default.
