+title: Appropriate Action Must be Setup When the Internal Audit Event Queue is Full
+
+description: |-
+ The audit system should have an action setup in the event the internal event queue becomes full.
+ To setup an overflow action edit <tt>/etc/audit/auditd.conf</tt>. Set <tt>overflow_action</tt>
+ to one of the following values: <tt>syslog</tt>, <tt>single</tt>, <tt>halt</tt>.
+
+
+rationale: |-
+ The audit system should have an action setup in the event the internal event queue becomes full

+ Verify the audit system is configured to take an appropriate action when the internal event queue is full:
+ <pre>$ sudo grep -i overflow_action /etc/audit/auditd.conf</pre>
+
+ The output should contain be like <tt>overflow_action = syslog</tt>
+
+ If the value of the "overflow_action" option is not set to <tt>syslog</tt>,
+ <tt>single</tt>, <tt>halt</tt> or the line is commented out, ask the System Administrator
+ to indicate how the audit logs are off-loaded to a different system or media.
