KCSA Kubernetes Security Fundamentals Practice Question
A security engineer wants to ensure that a pod cannot escalate its privileges to gain root access on the node. Which securityContext setting should be configured to prevent privilege escalation?
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
✓
allowPrivilegeEscalation: false
Setting allowPrivilegeEscalation: false in the container's securityContext ensures that a process cannot gain more privileges than its parent process (e.g., via setuid binaries).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
runAsNonRoot: false
Why it's wrong here
Setting runAsNonRoot to false permits running as root, which does not prevent privilege escalation.
- ✓
allowPrivilegeEscalation: false
Why this is correct
This directly prevents processes from gaining additional privileges, such as through setuid/setgid binaries.
- ✗
hostNetwork: true
Why it's wrong here
hostNetwork shares the host's network namespace, which is unrelated to process privilege escalation.
- ✗
privileged: true
Why it's wrong here
Setting privileged to true actually grants the container nearly all host access capabilities.
