Microsoft has recently announced that it is planning to enforce TLS (Transport Layer Security) 1.2 in its latest version of Office suite, i.e. 365. The company is silently deprecating the earlier versions i.e. 1.0 and 1.1 of this security. From March 1, 2018, it will become necessary for all client-server as well as browser-server combinations to use this latest or the further protocol versions in order to connect to Office 365 suite. If you don’t use TLS 1.2, you will not be able to access all the features of Office 365.
The latest version of TLS is getting huge support and the earlier versions, i.e. TLS 1.0 and TLS 1.2 have started to represent a big security threat. Microsoft, the tech leader has also assured the users that these earlier versions have no known security vulnerabilities that may harm your device and data.
However, the main reason behind deprecation or the disabling of both the older versions is to completely remove the chances of future protocol downgrade attacks along with the other Transport Layer Security vulnerabilities.
With the launch of TLS 1.3, you can expect more and more organizations to support TLS 1.0 and TLS 1.1, which is actually being recommended by this American multinational technology company. The company has also given a link to a recent white paper to provide the complete information about all the TLS 1.0 dependencies.
