KCSA Platform Security Practice Question
When configuring a Pod to run securely, which setting in the container's securityContext should be used to explicitly drop all default Linux capabilities and only retain required ones?
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
✓
capabilities.drop: ["ALL"]
The capabilities.drop field allows administrators to drop specific Linux capabilities (or 'ALL'), reducing the attack surface by removing root-like privileges from the container process.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
capabilities.drop: ["ALL"]
Why this is correct
Dropping 'ALL' capabilities removes all Linux capabilities, adhering to the principle of least privilege.
- ✗
runAsNonRoot: true
Why it's wrong here
While runAsNonRoot ensures the user ID is not 0, it does not manage Linux kernel capabilities directly.
- ✗
capabilities.add: ["ALL"]
Why it's wrong here
This would incorrectly attempt to add all capabilities, severely lowering the security posture.
- ✗
privileged: true
Why it's wrong here
Privileged mode grants all capabilities and disables container isolation features, which is the opposite of securing the container.
