Security Concerns and Costs
Ø Which network will you connect
your devices to?
Ø In compliance with Security?
² SSH? SSL? Radius or TACACS+?
Ø Extending your management
network may add cost to your
terminal server deployment.
² Network links between data centers
² Extra switch/hub ports
² Cost-per-port is a bad metric because
If your site is small, you may not have the security overhead, but as you move
into larger enterprises, there may be security policies that you need to be aware
of before you deploy, so you should investigate the security issues before you
buy hardware.
Determine which network(s) will host the terminal servers. Do you have
available network capacity? Sufficient physical space, power, and cooling?
Is your deployment in compliance with any existing security policies? (You
may not be able to connect to certain networks, or you may not be allowed to
extend those networks into certain non-secure areas, or you may need
permission first.)
You may plan to put the terminal servers on the management network for
security reasons. But find out if that network is currently in the area(s) where
you want to put the terminal servers. (You may need to use media converters
to let you use spare fiber between data centers, or add memory to routers to
allow you to use encrypted tunnels, etc.)
Do you have enough open network connections in those places, on those
networks, reserved for your terminal servers (or do you need to order more
hubs or switches)?
