Firefox, Chrome, Edge, and Safari To Disable Transport Layer Security TLS 1.0 and TLS 1.1 in 2020. The TLS protocol used to secure the web traffic, it provides confidentiality and integrity of data in transit between the server and client.
PCI council has already depreciated the TLSv1.0 and TLSv1.1 by June 30, 2018, now the TLSv1.2 remains as the minimum baseline for TLs support.
TLS 1.0 and TLS 1.1 affected with major vulnerabilities such as POODLE and BEAST, which allows an attacker to launch a man in the middle and other types of attacks to steal session cookies.
TLS 1.0 and TLS 1.1
TLS 1.0 was released in 1999 and TLS 1.1 in 2006, many versions have been released since the release including the current standard TLS 1.2 and the new one TLS 1.3.
The move comes as Internet Engineering Task Force (IETF) no longer recommends using the older versions of TLS versions.
TLS 1.0 does not support modern cryptographic algorithms, Firefox to disable TLS 1.0 and TLS 1.1 in March 2020 and will be appearing earlier in pre-release versions of Firefox.
Safari to remove TLS 1.0 and 1.1 with updates Apple iOS and macOS beginning in March 2020 and Microsoft to disable Microsoft Edge and Internet Explorer 11 in the first half of 2020.
Google Chrome to deprecate TLS 1.0 and TLS 1.1 in Chrome 72, and the protocols will be completely disabled in Chrome 81.
TLS 1.3 released last August with various improvement to perform a secure communication for online commerce, medicine, and other sensitive transactions.
TLS 1.3 removes old and unsafe cryptographic primitives, it is built using modern analytic techniques to be safer, it is always forward secure, it encrypts more data, and it is faster than TLS 1.2.
