General Concept

Run containers without root, period Take advantage of all security features the host provides

Configuring CRI-O:

Run containers with read-only images Limit the linux capabilities running within your container Set up container storage to modify the storage options in a more secure manner Configure alternative OCI Runtimes: Kata, Gvisord and Nabla to run locked down containers

Building images with security in mind.

Limit packages/attack surface of container images Build container images within a locked down kubernetes container

Advances in User Namespaces

Demonstrate running each container with a different User Namespace Configure system to take advantage of user namespace container separation, without taking a drastic speed hit
