Apple Ending Safari Support for TLS 1.0 and 1.1 in March 2020

by

safari iconApple today announced on its WebKit blog that it is ending support for TLS 1.0 and 1.1 starting in March 2020. TLS, or Transport Layer Security, is a security protocol used to protect web traffic.

Ahead of the planned deprecation, Apple recommends apps adopt TLS 1.2, which offers "security fit for the modern web." Upgrading from TLS 1.0 and 1.1 provides the following benefits, according to Apple:

- Modern cryptographic cipher suites and algorithms with desirable performance and security properties, e.g., perfect forward secrecy and authenticated encryption, that are not vulnerable to attacks such as BEAST.
- Removal of mandatory and insecure SHA-1 and MD5 hash functions as part of peer authentication.
- Resistance to downgrade-related attacks such as LogJam and FREAK.

TLS 1.2 is the standard on Apple platforms and already represents 99.6 percent of connections made from Safari. Apple says TLS 1.0 and 1.1 account for less than 0.36 percent of all connections.

Other browsers, including Firefox, Chrome, and Microsoft's Edge, are also planning to drop TLS 1.0 and 1.1 support starting in early 2020.

Good... there’s no reason to allow less secure communication protocols to continue functioning. It defeats the purpose of implementing stronger more secure protocols if we continue allow weaker entry points to function.

Curious to know what would happen to the small amount of apps/pages that don't update to TLS 1.2? Will they just stop working?
Essentially.

Which is a good thing.

Honestly I’m surprised they are waiting until then. At work we went round and disable everything below 1.2 both client and server side last year once Windows Vista went out of support (the last Windows OS to not support 1.2).

Guess I’ll be stuck using ancient versions of chrome/Firefox for a while longer. I get the reasons, but there are use cases in the enterprise realm where we need to connect to ancient internal systems. It’s not always easy upgrading a server due to various compatibility requirements.
The sad part is that if one brings it up to management, they would see 2020 as very far away and would never prioritize such an upgrade, even if it was easy.

Then when 2020 comes, big surprise and everyone starts running like chicken without their heads...

This should've been done this year or next year at the latest. 2020 is too far off.

Yes. The browser would deny the request because it can not negotiate a secure connection.
