KCSA Platform Security Practice Question
A security engineer is configuring a seccomp profile for a critical application pod running in a hardened Kubernetes cluster to restrict system calls. The pod requires access to the networking stack but must block module loading. Where must this custom JSON seccomp profile be placed on a worker node running containerd so that it can be referenced via the pod security spec?
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
✓
/var/lib/kubelet/seccomp/
Container runtime implementations like containerd look for custom seccomp profiles relative to the kubelet root directory, specifically inside the seccomp subdirectory (e.g., /var/lib/kubelet/seccomp/).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
/var/log/containers/
Why it's wrong here
This directory is designated for container log files, not system configuration or security profiles.
- ✗
/etc/kubernetes/manifests/
Why it's wrong here
The manifests directory is exclusively used for static pods managed directly by the kubelet.
- ✓
/var/lib/kubelet/seccomp/
Why this is correct
Kubelet and container runtimes look for localhost seccomp profiles relative to the kubelet root directory's seccomp folder.
- ✗
/etc/containerd/certs.d/
Why it's wrong here
This directory is used for configuring container image registry certificates, not seccomp profiles.
