The MQ Appliance network device must support organizational requirements to conduct backups of system level information contained in the information system when changes occur or weekly, whichever is sooner.
System-level information includes default and customized settings and security attributes, including ACLs that relate to the MQ Appliance network device configuration, as well as software required for the execution and operation of the device. Information system backup is a critical step in ensuring system integrity and availability. If the system fails and there is no backup of the system-level information, a denial of service condition is possible for all who utilize this critical network component.
This control requires the MQ Appliance network device to support the organizational central backup process for system-level information associated with the MQ Appliance network device. This function may be provided by the MQ Appliance network device itself; however, the preferred best practice is a centralized backup rather than each MQ Appliance network device performing discrete backups.
