In order to safeguard the university against imminent and persistent threats, two high risk network ports will be blocked at the university's internet gateway starting on Monday, May 29, 2017.
These two high risk ports, Remote Desktop Protocol (RDP) and Telnet, are extremely insecure, derived from legacy technologies, and currently unnecessary as there are much more preferable and secure means.
If you currently use RDP to remotely connect to your university resources, you need to connect to the university's Virtual Private Network (VPN) service first. The VPN service protects both you and the university with respect to remote connectivity. More information on the VPN service is available here.
If you currently use Telnet to connect from one university computer to another within the same network and/or to remotely connect to a university computer, you must instead use adequately and appropriately secure means such as SSH2 or SFTP (for file transfers).
Other high risk network ports are currently under consideration and analysis too and respective communications will be provided in advance of any remediation.
Please contact IST for any technical assistance. 780 492-9400 or firstname.lastname@example.org
Thank you for your diligence.
