Title

The Red Hat Enterprise Linux operating system must be configured so that the audit system takes appropriate action when there is an error sending audit records to a remote system. (Cat II impact)

Discussion

Taking appropriate action when there is an error sending audit records to a remote system will minimize the possibility of losing audit records. One method of off-loading audit logs in Red Hat Enterprise Linux is with the use of the audisp-remote dameon.

Check Content

Verify the action the operating system takes if there is an error sending audit records to a remote system. Check the action that takes place if there is an error sending audit records to a remote system with the following command: # grep -i network_failure_action /etc/audisp/audisp-remote.conf network_failure_action = syslog If the value of the "network_failure_action" option is not "syslog", "single", or "halt", or the line is commented out, ask the System Administrator to indicate how the audit logs are off-loaded to a different system or storage media, and to indicate the action taken if there is an error sending audit records to the remote system. If there is no evidence that the system is configured to off-load audit logs to a different system or storage media, or if the configuration does not take appropriate action if there is an error sending audit records to the remote system, this is a finding.

Fix Text

Configure the action the operating system takes if there is an error sending audit records to a remote system. Uncomment the "network_failure_action" option in "/etc/audisp/audisp-remote.conf" and set it to "syslog", "single", or "halt". network_failure_action = syslog
