KCSA Kubernetes Threat Model Practice Question
A cluster administrator is conducting a threat analysis regarding supply chain vulnerabilities in container registries and deployment pipelines. Which TWO of the following practices directly mitigate supply chain threats in Kubernetes? (Choose TWO)
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
✓
Enforcing cryptographic image signing and verification using tools like Sigstore Cosign
Supply chain security involves verifying software provenance and minimizing vulnerabilities. Using trusted signed base images and scanning images before deployment directly addresses supply chain vectors.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increasing the CPU limits on all worker nodes to handle larger container images
Why it's wrong here
CPU limits do not address supply chain integrity or vulnerabilities.
- ✓
Enforcing cryptographic image signing and verification using tools like Sigstore Cosign
Why this is correct
Correct. Image signing ensures that only artifacts from trusted build pipelines are deployed.
- ✗
Configuring static IP addresses for all worker nodes in the private subnet
Why it's wrong here
Static IP addressing is a network configuration practice, not a supply chain mitigation.
- ✓
Integrating automated vulnerability scanning into the CI/CD pipeline before pushing images to the registry
Why this is correct
Correct. Scanning images for known Common Vulnerabilities and Exposures (CVEs) before deployment prevents vulnerable code from entering the cluster.
- ✗
Disabling the default token automount on all namespaces globally
Why it's wrong here
Disabling token automount mitigates credential theft, not supply chain risks.
