Changes to SSH

As part of the University of Illinois' ongoing battle against cyberattacks, Technology Services is implementing changes to how people who are away from campus connect to on-campus resources. These changes will help keep our network safe, our data secure, and our services healthy.

On May 30, people who use the Secure Shell (SSH) protocol to connect to on-campus resources will have to use the University’s VPN

Why we're making this change

In the fall of 2016, the University began experiencing increased cyber attacks on our network that were negatively impacting campus resources, like email and Skype for Business.  Our data remain safe, but the process of warding off these brute-force attacks taxes the overall system. In some cases, crucial services needed to be restarted in order to work properly.

To minimize these impacts, in November, it was announced that a series of significant network changes would be made that affect how people connect to on-campus resources from off campus. This change to SSH is similar to other changes that were made in 2016 and 2017, and is the last planned change. 

Who is affected

Everyone who uses SSH to connect to computers on campus will be affected by this change. Customers who connect through SSH will need to first log in to the University's VPN. 

For more information on using the VPN as an off-campus customer, please see this Knowledgebase article.

What you can do

If you are not already using VPN to connect through SSH, please begin doing so by May 30, 2017. The University's VPN service is free and easy to use.
