iPATH Agility Controller
2.3.3 User Types
This guide refers to the two main categories of users involved with the iPATH Agility Controller system:
• An Admin (administrator) user accesses the iPATH Agility Controller system via a network-linked computer running an
Internet browser. Once the necessary username and password have been entered, Admin users can make changes to the
operation of the iPATH Agility Controller system.
• A Regular user has a keyboard, video monitor and mouse (plus speakers where appropriate) attached to a Agility receiver unit
and can access one or more computers that are linked to Agility transmitters. The Agility receiver provides an On-Screen Display
(OSD) that lists all accessible computers and allows easy access to them.
2.3.4 Security
Security considerations form a major part of iPATH Agility Controller operation, ensuring that users have rapid access only to the
systems for which they have permission. At its core, iPATH Agility Controller manages an important three-way relationship
between the users, the Agility receiver(s) and the channels from the host computers.
The diagram shows a representation of the three-way relationship which exists between users, receivers and channels, as shown
in Figure 2-3:
To successfully gain access to a channel:
• The user requires permission to use the receiver,
• The receiver requires permission to connect with the channel,
AND
• The user must have permission to access the channel.
In most cases, the need for three access permissions per connection is unnecessary and raises administration overheads. Hence, by
default, iPATH Agility Controller grants open access for the user to the receiver and the receiver to the channel while restricting
the final, most crucial piece of the puzzle. For those who require it, the lock upon the user to receiver stage can be applied
individually or globally.
