Verify the action the operating system takes if the disk the audit records are written to becomes full. To determine the action that takes place if the disk is full on the remote server, use the following command: # grep -i disk_full_action /etc/audisp/audisp-remote.conf disk_full_action = single To determine the action that takes place if the network connection fails, use the following command: # grep -i network_failure_action /etc/audisp/audisp-remote.conf network_failure_action = stop If the value of the "network_failure_action" option is not "syslog", "single", or "halt", or the line is commented out, this is a finding. If the value of the "disk_full_action" option is not "syslog", "single", or "halt", or the line is commented out, this is a finding.

To determine the action that takes place if the network connection fails, use the following command:

# grep -i network_failure_action /etc/audisp/audisp-remote.conf
network_failure_action = stop

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