Secure Renegotiation in PANOS 9x?

[richardhicks]

I'm seeing some posts stating that Secure Renegotiation is not supported on the Palo Alto platform. Is this still true for the latest release, v9.x? If so, how is it enabled?

@richardhicks,

I'm fairly certain that TLS Renegotiation was fixed in an update to 6.0, so it's been available for a while. Regardless renegotiation is dying anyways; TLS 1.3 removes it completely.

Good to hear. So how to enable it? I'm certainly glad that TLS 1.3 eliminates it, but my customer has TLS 1.2 at the moment and need to elminate this audit finding. 🙂

Hi @richardhicks 

At least on a global protect portal website secure renegotiation is still not supported ... so I assume this also applies to inbound decryption.

@BPry 

What do you think when TLS1.3 support will be added? I would saysomewhere in 2021 😛 (with PAN-OS 10?)

@vsys_remo,

Last I heard it was still being targeted for 9.1**, but it wouldn't suprise me at all of this got pushed back to 10*. There's some really interesting papers you can find that speak in detail about the additional issues with TLS 1.3 and attempting to intercept that communication in a passive format.
