ISC2 Certified Cloud Security Professional (CCSP) Practice Question

Your organization is refactoring a monolithic web shop into several microservices that will be deployed as containers on a managed Kubernetes cluster. Security wants the strongest possible runtime isolation so that, even if an attacker obtains root inside one container, they cannot escape to the node's kernel or gain access to other namespaces-without forcing developers to rewrite code. Which approach best meets this requirement?

  • Apply custom AppArmor profiles to every node to limit the system calls available to containers.

  • Enable Kubernetes PodSecurityPolicies to drop all privileged capabilities and enforce non-root containers.

  • Create default-deny Kubernetes network policies between namespaces and only whitelist required service ports.

  • Run each microservice with a hypervisor-isolated container runtime (e.g., Kata Containers) so every pod executes inside a lightweight VM.
