As part of our continuing efforts to enhance IT security, SMU OIT will start to deprecate older Transport Layer Security (TLS) 1.0 & 1.1 protocols from several SMU web-based services, including www.smu.edu, Webmail, and my.SMU on Thursday, September 26, 2019.
Few users should be impacted, as the TLS 1.0/1.1 protocols have already been disabled by popular service providers for other campus services, including Box@SMU and Microsoft Office 365. However, some users with older versions of browsers, email clients and/or operating systems may be required to upgrade before September 26, 2019, in order to continue accessing these resources. This process will be completed over several weeks, so some services might be available to older web browsers while others will require a browser that supports the newer security protocols. SMU OIT recommends keeping these resources up to date in order to ensure the latest security patches, as this helps protect our users against malware and other malicious exploits.
Updated 09/24/2019: Clarified that the update will be completed over several weeks.
