Fix Text (Documentation Requirement)

The responsible MQ systems programmer(s) shall create and maintain a spreadsheet that contains a list of all Production WebSphere MQ Remotes, associated individual USERIDs with corresponding valid Certified Name Filters (CNF). This documentation will be reviewed and validated annually by responsible MQ systems programmer(s) and forwarded for approval by the ISSM. The ISSO will define the associated USERIDs, the CNF, and grant the minimal need-to-know access by granting only the required resources and Commands for each USERID in the ACP. Refer to IBM WebSphere MQ Security manual for details on defining CNF for WebSphere MQ. Generic access shall not be granted such as resource permission at the SSID. MQ resource level.
