PA newbie here! I am digging in to the PA traffic processing algorithm & on the 4th leg of the process I see that the traffic is allowed at this point but gets scanned against the configured security profile. This sounds like where IPS comes into the picture am I correct? I read the PAN-OS 8.0 Admin Guide and I don't see anything that mentions IPS but maybe its just not using the term in the guide. Is it safe to assume that IPS comes into play at this point in the process?
The PAN does parrallel processing of packets so it does quite a few things at once to keep things moving quickly. Check out this article and see if helps out:
