Major browsers deprecating Transport Layer Security(TLS)1.0 and 1.1 in March 2020.

Hi All,

I'm not sure of how many of us have seen the PSN below from Avaya:

If I've read it right, then major browsers (IE/Firefox/Chrome) will no longer support TLS 1 and 1.1 from March 2020. Once TLS 1.0 and TLS 1.1 have been deprecated we won't be able to HTTP/HTTPS onto various Avaya systems.

We've still got a lot of customers running older versions of CM/AES/SMGR/CMM/AMM/US so this is going to cause us a few issues.

Has anyone considered this and got a workaround?

I've been thinking of a Virtual Machine on my laptop (Virtualbox) running Win7 without any updates to IE etc and I'd use that whenever I need to browse onto a CM etc.

Thanks

Glimma

I saw this and I'm concerned as I still have lots of Avaya 6.3 in production. I'm working the upgrade to 7, but its taking time. This is going to be a problem for a lot of people. I tested this yesterday by setting my IE to only use TLS 1.2 and all my Avaya 6.3 webUI's would NOT respond. I think your work around is the only valid solution. Don't upgrade your browser or setup a VM with an old browser that doesn't upgrade and direct all webUI use to that.

I'll be following this thread as this appears to be a big issue for anyone with older stuff.

portable version of old chrome/firefox is good too. You can't just install an old version of Firefox or Chrome - it'll just upgrade itself no matter how you try to stop it.

I got c:\oldfirefox running 52.3 ESR. I think around release 53, Firefox went to "Quantum" which is basically a rewrite from the ground up and deprecated a lot of add-ons, some of which i couldn't live without.

I have no problem running old and new firefox on my machine with the condition I can only run one at a time.
