+title: 'Ensure System Log Files Have Correct Permissions'
+
+description: |-
+ <p>Log files record system operations. The log tool <tt>rsyslog</tt> can record logs
+ to specified files. When the specified log file does not exist in the system,
+ <tt>rsyslog</tt> can create a new log file. You can set the permission on new log files
+ in the <tt>rsyslog</tt> configuration file. You can set the default file permission to
+ ensure that new log files have proper and secure permissions.</p>
+ <p>Run the following command to manually check whether the log permission is properly set:</p>
+ <pre>$ ls -l <i>LOGFILE</i></pre>
+ <p>If the permissions are not 600 or more restrictive, run the following
+ command to correct this:</p>
+ <pre>$ sudo chmod 0600 <i>LOGFILE</i></pre>"
+
+rationale: |-
+ Log files can contain valuable information regarding system
+ configuration. If the system log files are not protected unauthorized
+ users could change the logged data, eliminating their forensic value.
