SLEM 5 must offload audit records onto a different system or media from the system being audited.

Information stored in one location is vulnerable to accidental or incidental deletion or alteration.

Offloading is a common process in information systems with limited audit storage capacity.

Verify what action the audit system takes if it cannot offload audit records to a different system or storage media from SLEM 5 being audited.

Check the action that the audit system takes in the event of a network failure with the following command:

     > sudo grep -i "network_failure_action" /etc/audisp/audisp-remote.conf
     network_failure_action = syslog

If the "network_failure_action" option is not set to "syslog", "single", or "halt" or the line is commented out, this is a finding.

Configure SLEM 5 to take the appropriate action if it cannot offload audit records to a different system or storage media from the system being audited due to a network failure.

Add or modify the following line in the "/etc/audisp/audisp-remote.conf" file:

network_failure_action = syslog
