Information
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.).
Solution
Edit the following lines in the /etc/rsyslog.conf and /etc/rsyslog.d/*.conf files as appropriate for your environment.
NOTE: The below configuration is shown for example purposes only. Due care should be given to how the organization wish to store log data.
*.emerg :omusrmsg:*
auth,authpriv.* /var/log/secure
mail.* -/var/log/mail
mail.info -/var/log/mail.info
mail.warning -/var/log/mail.warn
mail.err /var/log/mail.err
cron.* /var/log/cron
*.=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:
