Update to wireless network certificates

Incident Report for Missouri S&T IT Services & Systems

Identified

Missouri S&T Information Technology is updating the security certificates used for campus wireless authentication.

This maintenance is necessary due to a global security issue involving a certificate authority whose trust has been revoked. This global issue affects organizations worldwide and requires the replacement of impacted security certificates. This is an industry-wide issue and is not the result of a security incident at Missouri S&T.

During this update, mobile devices may prompt users to accept new certificates. Most laptops should automatically recognize the updated certificates without requiring user action.

If you experience connection issues, please contact the S&T IT Help Desk at https://it.mst.edu/.
