Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Seccomp profile
Why this is correct
Correct: Seccomp limits syscalls, directly reducing kernel attack surface.
- ✗
Read-only root filesystem
Why it's wrong here
Prevents writes to container filesystem but does not limit syscalls.
- ✗
Resource limits (CPU/memory)
Why it's wrong here
Resource limits prevent DoS but not kernel compromise.
- ✗
Image vulnerability scanning
Why it's wrong here
Scanning identifies known vulnerabilities but does not prevent runtime attacks.
