Verify what action the audit system takes if it cannot off-load audit records to a different system or storage media from the SUSE operating system 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.

Verify what action the audit system takes if it cannot off-load audit records to a different system or storage media from the SUSE operating system 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.

Fix Text (F-38129r619204_fix)
Configure the SUSE operating system to take the appropriate action if it cannot off-load audit records to a different system or storage media from the system being audited due to a network failure. Uncomment the "network_failure_action" option in "/etc/audisp/audisp-remote.conf" and set it to "syslog", "single", or "halt". See the example below: network_failure_action = syslog
