filter ssh v1

Hi

I have a request to filter in the firewall ssh v1. Is there any way to identify and filter ssh v1? can the firewall identify ssh v2 some way?

Hi Cesar,

ssh is at least listed in the applipedia as a known App.

Thanks Roland

The problem I have is that I don't see any reference to the version of SSH in the app description. I will like to know if there is any mechanism to diferentiate v1 from v2, so I can permit only v1.

It seems the APP does not differentiate between ssh1 and ssh2, just my guess....

You can setup a SSH decryption policy to handle ssh vs ssh-tunnel. But I dont think it currently supports stuff like v1 vs v2.

Look at page 143 in the PA-4.1_Administrators_Guide.pdf for more info.

I think you need to contact your sales rep. to file this as a feature request.

I can see 'SSH2 Login Attempt' (ID:31914) under vulnerability protection signature.

If you permit ssh in security rule and block this signature  on the same rule,

can't you permit ssh v1 only?

Just my guess.

Regards,

Emr
