220 Ensuring a Secure Dell OpenManage IT Assistant Installation
Setting Up Additional Security for IT Assistant
Access
So far in this section, security has been addressed with respect to the existing
TCP/IP connection between IT Assistant and the managed system. In
addition to these security precautions, Microsoft Terminal Services, which
allows uncharted remote connection only by users with administrator
accounts (administrative mode), can also be used to limit user interface
connections to a system running IT Assistant user interface and Services.
An example of a network which leverages Terminal Services is shown in
Figure 11-2.
