RADIUS authentication: MS-CHAP v2?

L3 Networker

Currently, my PA-3050 devices (PAN-OS 6.1.12) utilize RADIUS authentication.  I know that this uses the completely unencrypted PAP protocol.

 

I have asked PAN about MS-CHAP v2 support in the past and was told that the device must be placed into FIPS mode in order to gain the ability to do RADIUS authentication over MS-CHAP v2, but by putting a device into FIPS mode you are effectively performing a factory reset.

 

I've always thought that was completely ridiculous.  If the device supports MS-CHAP v2 in FIPS mode, it's clearly capable of using the protocol.  Why not make MS-CHAP v2 available in standard mode as a choice over PAP?


In any case, I've seen that PAN has removed the FIPS mode from newer PAN-OS releases.  As such, is PAN adding MS-CHAP v2 support?  Or are they dropping MS-CHAP v2 support entirely along with the associated FIPS mode?

Well, I guess it's good that they have finally moved beyond PAP, but it's a shame they aren't using MS-CHAP v2 which is the most secure RADIUS authentication protodcol available.

Hi Scottsander,

 

As CHAP has only just been implemented, I'm sure MS-CHAP v2 is around the corner. I'm sure you could also speak to your account manager to raise this as a Feature request to add in future releases.

 

Thanks

Jack

 

 

I already did that three years ago.
