XK0-006 Practice Question: A security policy requires that containers run…
A security policy requires that containers run with minimal privileges. Which THREE measures should be implemented? (Select THREE.)
⚠ Common exam trap
Candidates often think that 'minimal privileges' only means running as non-root, when in fact seccomp profiles and capability dropping are equally critical to enforce kernel-level restrictions and prevent syscall-based exploits.
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
✓
Use --security-opt seccomp=default
The `--security-opt seccomp=default` flag applies the default seccomp (secure computing mode) profile, which restricts the system calls available to the container. This enforces the principle of least privilege by blocking dangerous syscalls (e.g., `mount`, `reboot`) while allowing necessary ones, reducing the attack surface without manual profile creation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use --security-opt seccomp=default
Why this is correct
The default seccomp profile restricts system calls, improving security.
- ✗
Mount host filesystem read-write
Why it's wrong here
This grants the container write access to the host, violating minimal privilege.
- ✓
Run as non-root user
Why this is correct
Running as non-root limits the impact of a container compromise.
- ✗
Expose all ports to host
Why it's wrong here
Exposing all ports increases the attack surface; only expose necessary ports.
- ✓
Drop all Linux capabilities and add only required
Why this is correct
Capabilities should be minimized; drop all and add back only what is needed.
