Getting Data In

What is S2S Protocol Specification?


Good Morning,

I’m looking for the specification of the S2S protocol.

We have some trouble with getting splunk uf data through a Palo Alto Firewall. 
the firewall has a Application Profile Engine.

So it not just looks at layer 4 for IP/Port and Protocol but also certain Aspekts of the packet like headers….

There is no predefined profile for splunk S2S so we need to create it, but I can‘t find the docs for Protocol definition. 
We are aware of the fact that it is possible to bypass this App engine and do a layer 4 filtering.

But it would be the only application in the company to do that and the fact that it would be for a Internet facing service and a security service seams  off. 🫣

We where adviced to use S2S over HEC for Stability reasons if it does not work out we have to switch but for now we want to try make it work.

The Splunk-to-Splunk protocol is proprietary.  There are no public documents about it.
