On Tuesday, June 26th, from 6 to 8 am, CCS will be performing maintenance on the campus Internet firewall in an effort to continually improve our security posture and reduce our overall attack surface. Security rules will be implemented to block a number of known dangerous applications based on application signatures. No service interruption is expected.
A complete list of all ports that have already been blocked and applications that are in-scope for this change be found here - https://www.uoguelph.ca/ccs/infosec/blockedports
