For some reason I am unable to see any events being generated for denied IP addresses when running a container defender on one of our hosts.
Did the following:
Based on the above I expected to see host audit events alerting me to the denied IP address under Admin->Compute->Monitor->Events. But there is no activity.
If I do the exact same steps, but instead of adding an IP i add a port (e.g. 80,443) to the denied ports list, then I start to see activity in Monitor->Events immediately. So looks like the defender is able to detect some things from the host, but not IP connectivity for some reason.
Anybody have an idea of what is going on? And perhaps how to debug the issue? Or is there something fundamental I don't understand with host protection and container defenders.
But for some reason I don't see any events/alerts being generated when I try to ping or curl an IP that
To block dns at the host level, please install host defender on your linux host, and create a host policy.
Here is the documentation of runtime defense for hosts:
And to install host defender please refer to the following documentation:
Thanks for your reply, USheikh. My understanding of the container defender vs host defender is that the container defender does everything that the host defender does, so if a host runs the docker daemon then one should install a container defender (https://docs.paloaltonetworks.com/prisma/prisma-cloud/prisma-cloud-admin-compute/install/defender_ty...). But based on your answer, do I have to install both a container defender AND host defender to get full protection on the host?
Yes, they are very similar. The key difference is host protection is more geared towards the system services/apps that reside on the hosts - typically they need to be systemd services
