I'm running a cluster of PA (4.0.8) with SSL Decryption configured.
SSL Decryption is not able to decrypt SSL traffic if the HTTPS session is using TLS 1.1 or TLS 1.2.
Test with www.gmail.com
Chrome : OK (see gmail application in the traffic log)
Firefox : idem
IE 8 or 9 with TLS 1.1 or TLS 1.2 DISABLED : idem
IE 8 or 9 with TLS 1.1 or TLS 1.2 ENABLED : see only SSL application
Is it solved in 4.1.6 (I plan to upgrade my cluster with this release) ??
we currently do not support decryption of TLS1.2. TLS 1.2 hasn't be broadly supported by browsers until more or less practical TLS 1.0 and block cipher related attacks where demonstrated by cryptographers as proof of concept code. We do see a slow increase of TLS 1.2 support in major browsers lately. Especially Google Chrome and Apple Safari support in their standard configuration now. Since PANOS 5.0, if we detect a TLS1.1 or TLS1.2 session, we first try to downgrade it to TLS1.0 and decrypt. If that fails, we won't decrypt the session and either drop the session or allow it encrypted based upon your policy settings.
First, thanks for your answer.
The document only mention SSL2.0, 3.0 and TLS 1.0. No infos about TLS 1.1 or TLS 1.2...
In my case, we don't have any problem with the certificate itself because the SSL interception is not doing it's job...
I will upgrade 4.1.6 and keep you inform if it's solved or not...
I have been in relation for months with product and support managers, it was said many times that 1.1 is not supported and 1.0 is partially (lack of critical extensions).
Strange we don't have same informations :smileygrin:
Anyway, I am always running my own tests and found out that above SSLv2, compatibility is poor.
