What about accessing campus devices from outside the network? Normally most access will be carried out from on-site from within the campus NOC but what about if you're not at the NOC? What about if you're away? You may be at home working at home, you may be traveling for a business or educational or research meeting and you end up being completely off campus. The solution here is a jumphost. What a jumphost is is basically a secure shell server host and that's all it does. Running inside the NOC it only listens on the ssh port and has no other services running. You will connect in there and then you will use ssh onwards to the campus devices. The alternative is to use a secure VPN access server but the advantage with the ssh server host as the jumphost is that you can build it yourself, it's not expensive and a simple device that you can set up.
