Fix Recommendation

Obtain the Command and AO approval for the implementation or transition to UC soft clients as the primary endpoints in writing.

Approval documentation must be maintained by the ISSO for future inspection by IA reviewers or auditors. If Command and AO written approval is not available, hardware endpoints must be used as the primary endpoints.

NOTE: This requirement is in addition to AO approval for deploying UC soft clients on DOD networks. When UC soft clients are deployed as the primary endpoint, additional risks to availability exist.
