You will install Management and Security Server 12.6 SP1 and Reflection Desktop 16.2 on the same Windows workstation, provided you have both an administrator logon and a user logon.
(This approach is ok for testing, but not for production.)
Then you will use Management and Security Server to:
assign sessions to only authorized users.
configure secure connections to host applications.
restrict users’ access to application settings.
See the Configuration Overview for a high-level view of the tasks.
