However, pulling out the legacy versions wasn’t easy for all the adopters as it presented a few challenges including the requirement to maintain backward compatibility.
In January 2021, the National Security Agency (NSA) released guidance on eliminating obsolete TLS configurations, and many technology giants including Apple, Google, Mozilla and (now) Microsoft have announced plans to move from the outdated protocols.
Several Microsoft applications are set to break
Microsoft has warned enterprise users about a list of applications that can be expected to break as older TLS versions are disabled. Topping the list of endangered applications is SQL Server.
The 2012, 2014, and 2016 editions of the SQL Server are expected to break. While both 2014 and 2016 still remain in support, 2012 is out of support but will receive extended security updates.
Other popular applications listed in the red zone by the company include MS Office 2008 Professional, Safari 5.1.7, EVault Data Protection-7.01.6125, and Xbox One SmartGlass – 2.2.1702.2004.
Microsoft has advised upgrading applications that show hints of failure after the change. “Most newer versions of applications support TLS 1.2 or higher protocol versions,” Microsoft said. “Therefore, if an application starts failing after this change, the first step is to look for a newer version of the application that has TLS 1.2 or TLS 1.3 support.”
