Title

The SUSE operating system must off-load audit records onto a different system or media from the system being audited. (Cat II impact)

Discussion

Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading is a common process in information systems with limited audit storage capacity.

Check Content

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

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
