Linux Foundation Certified Kubernetes Security Specialist (CKS) Sample Questions (Q48-Q53):

NEW QUESTION # 48
You are responsible for securing the Kubernetes clusters supply chain. Your organization utilizes a private Docker registry to host container images. Currently, images are built and pushed to this registry without any validation or signing. How can you implement a policy to ensure that only signed and verified images are deployed to the cluster?

Answer:

Explanation:
Solution (Step by Step) :
1. Set Up a Signing Authority:
- Choose a trusted entity (e.g., a dedicated server or a dedicated user account) to act as the signing authority.
- Generate a private and public key pair using tools like 'openssr or 'gpg'
- Store the private key securely and ensure only authorized individuals have access.
2. Configure Image Signing:
- Create a script or integrate signing into your image build process.
- when building an image, use the private key from the signing authority to sign the image.
- The signing process embeds a digital signature within the image manifest.
3. Integrate Image Verification
- Configure the Kubernetes cluster to enforce image signature verification.
- Utilize tools like 'admission webhookS to inspect incoming images.
- The webh00k will check if the image has a valid signature from the trusted authority.
- If the signature is invalid or missing, the deployment will be blocked.
4. Example Implementation (using 'cosign'):
-

5. Integrate with CI/CD pipelines: - Integrate image signing and verification into your automated CI/CD pipelines. - This ensures consistency and prevents accidental deployment of unsigned images.
