KCSA Platform Security Practice Question
A platform engineer wants to configure a container runtime security tool that monitors system calls and sends alerts about potential threats in a Kubernetes cluster. Which component of the container runtime architecture intercepts these system calls?
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
✓
eBPF kernel probes
The Linux kernel relies on security modules and tracing mechanisms, while the container runtime uses interfaces like seccomp or Linux Security Modules (LSM) to interact with the kernel. Container runtime monitors often use eBPF programs attached to kernel tracepoints to observe system calls without modifying the kernel.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
eBPF kernel probes
Why this is correct
eBPF allows safe execution of programs in the Linux kernel space to capture system calls and monitor runtime behavior efficiently.
- ✗
The coreDNS plugin
Why it's wrong here
CoreDNS manages cluster internal DNS resolution and does not intercept system calls.
- ✗
The Kubernetes storage controller
Why it's wrong here
Storage controllers manage persistent volumes and have no visibility into container execution or system calls.
- ✗
The kube-apiserver admission webhook
Why it's wrong here
Admission webhooks validate API requests, not the runtime system calls made by running containers.
