5.1.2.5 Ensure logging is configured (Manual)
Profile
- Level: 1 - Server
- Level: 1 - Workstation
- Assessment Status: Manual
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
Command Line
Review the contents of /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 as expected:
ls -l /var/log/
Expected Result
Log files should exist and be actively receiving log data appropriate for the system.
Remediation
Command Line
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:*

local0,local1.* -/var/log/localmessages
local2,local3.* -/var/log/localmessages
local4,local5.* -/var/log/localmessages
