CCSP Cloud Platform and Infrastructure Security Practice Question
A security auditor is reviewing a Kubernetes cluster and identifies that containers are running as root with full Linux capabilities. Which TWO security measures would help mitigate container escape risks in this environment?
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
✓
Set the container to run as a non-root user
Dropping all Linux capabilities and setting the container to run as a non-root user are effective. Running with a read-only root filesystem also helps, but the question asks for two measures: dropping capabilities and using a non-root user are the most direct.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set the container to run as a non-root user
Why this is correct
Running as non-root reduces the impact of a compromise.
- ✗
Enable host networking mode
Why it's wrong here
Host networking mode gives the container access to the host network stack, increasing risk.
- ✗
Use a privileged container
Why it's wrong here
Privileged containers have all capabilities and should be avoided.
- ✓
Drop all Linux capabilities except those needed
Why this is correct
Reducing capabilities limits the container's ability to perform privileged operations.
- ✗
Mount the host filesystem as read-write
Why it's wrong here
Mounting host filesystem gives the container access to host files, increasing escape risk.
