CPENT Cloud And Hybrid Infrastructure Security Practice Question
When reviewing container security and Kubernetes cluster configurations, which THREE practices or misconfigurations commonly lead to container escapes or host compromise? (Choose three)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Exposing sensitive host directories (such as '/' or '/proc') via 'hostPath' volumes.
Common container security issues include mounting the Docker socket, running containers in privileged mode, and exposing sensitive host paths.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Using a non-root user directive (USER 1000) inside the Dockerfile.
Why it's wrong here
Incorrect. Running as a non-root user is a security best practice that hinders, rather than helps, container escapes.
- ✓
Exposing sensitive host directories (such as '/' or '/proc') via 'hostPath' volumes.
Why this is correct
Correct. Mounting host root directories allows direct manipulation of host files, cron jobs, or binaries.
- ✓
Enabling the 'privileged: true' security context flag in the pod specification.
Why this is correct
Correct. Privileged containers disable all kernel namespaces and cgroups isolation, granting full access to the host.
- ✓
Mounting the Docker daemon UNIX socket (/var/run/docker.sock) inside a container.
Why this is correct
Correct. Access to docker.sock allows a container to create sibling containers with host mounts, easily escaping the container.
- ✗
Enabling Kubernetes Role-Based Access Control (RBAC) with least-privilege binding.
Why it's wrong here
Incorrect. Least-privilege RBAC is a hardening control, not a misconfiguration.
