Question regarding Customer Advisory "Content Delivery Network Infrastructure Update"

Anon1 — Mon, 20 Jan 2020 08:37:13 GMT

There is a new Customer Advisory "Content Delivery Network Infrastructure Update".

https://live.paloaltonetworks.com/t5/Customer-Advisories/Content-Delivery-Network-Infrastructure-update/ta-p/307121

We use AppID "paloalto-updates" to allow download of updates. Does this need to be adapted?

The firewall devices are configured to use update server "updates.paloaltonetworks.com". Does this need to be adapted?

Unfortunately the Customer Advisory does not elaborate on this.

Hello,

If you are using URL filtering to download your PAN updates, then yes you should update the PAN to allow that URL. If you are letting your PAN hit anything on the internet and just using app-id to filter, then probably (BTW I dont recommend this method).

I know its a bit vague, however I would say have a policy that allows the PAN to go and get updates, but only from the Palo Alto URL's and specify app-ids. This is very narrow/specific policy and will allow your PAN to get updates.

Regards,

I think @Anon1 was asking about the following value where normally updates.paloaltonetworks.com is configured:

Thanks for all your answers. Yes, I meant the "Update Server" setting on the firewall devices.

@OtakarKlier : Do you mean to create a custom URL category object with the *.paloaltonetworks.com URLs and attach it to the firewall rule with the paloalto-updates appid? Isn´t this redundant? I assume the paloalto-updates appid does exactly this (allow access only to the relevant resources for the update service.)

Hello,

Exactly, a custom URL category with the update URL's.
