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) ??
Solved! Go to Solution.
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...
After upgrading to 4.1.6, I can confirm PA is NOT ABLE to decrypt TLS 1.1 or TLS1.2.
I'm waiting an OFFICIAL answer from PA now : When will it be supported ???
as far as i know later Versions of TLS are currently not supported.
This Information was from PanOS 4.0.x
but since i didn't see anything in the Release Notes of 4.1.x it should be still correct.
I totally second your claims. In addition TLS 1.0 is partially finished : it lacks TLS Extensions, which make for example https://www.gmail.com to fail decryption.
According to Chrome dev team, newest version has TLS 1.1 disabled because of issues with IIS : Chrome Releases: Stable Channel Update
Thank you Microsoft, you're saving us for once :smileysilly:
This is answer is receiver from my local SE.
"TLS v1.1 should be supported as of v4.0.x.
I found a note that if diffie hellman is used in the key establishment we can’t decrypt."
"v1.2 seems to be targeted for the next major release (5.x)."
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.
Would TLS 1.1 and 1.2 be decrypted by PANOS 5.0 for now?
TLS 1.1 with differ hellman could no be decrypted on PANOS 5.0 also?
