KCSA Kubernetes Threat Model Practice Question
An engineer is reviewing the threat model of a Kubernetes cluster exposed to the public internet via a LoadBalancer service. Which configuration flaw most commonly leads to unintended external exposure of administrative dashboards?
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
✓
Exposing management dashboards via LoadBalancer or NodePort services without authentication or IP whitelisting
Deploying management tools (like Kubernetes dashboards, monitoring UIs, or debugging tools) with external LoadBalancer services or NodePorts without authentication or network restriction is a major threat vector.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configuring liveness probes with HTTP GET requests instead of TCP socket checks
Why it's wrong here
Probe types affect health checking mechanisms, not external network exposure.
- ✓
Exposing management dashboards via LoadBalancer or NodePort services without authentication or IP whitelisting
Why this is correct
Unauthenticated or loosely secured dashboards exposed to the public internet allow arbitrary attackers to gain administrative cluster control.
- ✗
Setting imagePullPolicy to IfNotPresent on production deployments
Why it's wrong here
imagePullPolicy controls when the kubelet downloads images, unrelated to service exposure.
- ✗
Using ClusterIP service types for internal database connectivity
Why it's wrong here
ClusterIP services are internal-only by default and do not expose services to the public internet.
