Linux Foundation Certified Kubernetes Security Specialist (CKS) 認定 CKS 試験問題 (Q16-Q21):質問 # 16
You must complete this task on the following cluster/nodes: Cluster: immutable-cluster Master node: master1 Worker node: worker1 You can switch the cluster/configuration context using the following command: [desk@cli] $ kubectl config use-context immutable-cluster Context: It is best practice to design containers to be stateless and immutable.  Task: Inspect Pods running in namespace prod and delete any Pod that is either not stateless or not immutable.  Use the following strict interpretation of stateless and immutable: 1. Pods being able to store data inside containers must be treated as not stateless.  Note: You don't have to worry whether data is actually stored inside containers or not already. 2. Pods being configured to be privileged in any way must be treated as potentially not stateless or not immutable.

質問 # 17
Context
A PodSecurityPolicy shall prevent the creation of privileged Pods in a specific namespace.
Task
Create a new PodSecurityPolicy named prevent-psp-policy,which prevents the creation of privileged Pods.
Create a new ClusterRole named restrict-access-role, which uses the newly created PodSecurityPolicy prevent-psp-policy.
Create a new ServiceAccount named psp-restrict-sa in the existing namespace staging.
Finally, create a new ClusterRoleBinding named restrict-access-bind, which binds the newly created ClusterRole restrict-access-role to the newly created ServiceAccount psp-restrict-sa.

質問 # 18
You are configuring a Kubernetes cluster with a deployment named 'secure-app' that uses a secret named 'my-secret to access sensitive information You need to implement an Admission Controller webhook to enforce a policy that prevents the deployment from starting if the 'my-secret secret is not present in the cluster.
正解：
解説：
Solution (Step by Step) :
1. Create a Deployment with a Secret Dependency:
- Create a Deployment YAML file named 'secure-app-deployment.yaml that depends on the 'my-secret secret.

2. Create the Admission Controller Webhook Server: - You will need to create a server that will implement the Admission Controller webhook logic This can be a simple web server written in any language that can receive and process AdmissionReview requests. - Here's an example in Node.js using the 'express' framework:

3. Configure the Admission Controller Webhook in Kubernetes: - Create a ValidatingWebhookConfiguration YAML file named 'secure-app-webhook.yaml that specifies the webhook configuration:

- Create the Webhook Service: - Create a Service YAML file named 'secure-app-webhook-service.yamr to expose the webhook server:k

4. Apply the Webhook Configuration and Service: - Apply the YAML files using kubectl apply -f secure-app-webhook.yaml secure-app-webhook-service.yaml 5. Test the Admission Controller: - Try creating the 'secure-app' deployment without the 'my-secret' secret. The deployment creation should fail, and you should see the message from the webhook server - Create the 'my-secret' secret and then try creating the 'secure-app' deployment again. The deployment should now be created successfully.

SIMULATION
You can switch the cluster/configuration context using the following command:
[desk@cli] $ kubectl config use-context qa
Context:
A pod fails to run because of an incorrectly specified ServiceAccount
Task:
Create a new service account named backend-qa in an existing namespace qa, which must not have access to any secret.
Edit the frontend pod yaml to use backend-qa service account
Note: You can find the frontend pod yaml at /home/cert_masters/frontend-pod.yaml
正解：
解説：
See the Explanation belowExplanation:
[desk@cli] $ k create sa backend-qa -n qa
sa/backend-qa created
[desk@cli] $ k get role,rolebinding -n qa
No resources found in qa namespace.
[desk@cli] $ k create role backend -n qa --resource pods,namespaces,configmaps --verb list
# No access to secret
[desk@cli] $ k create rolebinding backend -n qa --role backend --serviceaccount qa:backend-qa
[desk@cli] $ vim /home/cert_masters/frontend-pod.yaml
apiVersion: v1
kind: Pod
metadata:
name: frontend
spec:
serviceAccountName: backend-qa # Add this
image: nginx
name: frontend
[desk@cli] $ k apply -f /home/cert_masters/frontend-pod.yaml
pod created
[desk@cli] $ k create sa backend-qa -n qa
serviceaccount/backend-qa created
[desk@cli] $ k get role,rolebinding -n qa
No resources found in qa namespace.
[desk@cli] $ k create role backend -n qa --resource pods,namespaces,configmaps --verb list role.rbac.authorization.k8s.io/backend created
[desk@cli] $ k create rolebinding backend -n qa --role backend --serviceaccount qa:backend-qa rolebinding.rbac.authorization.k8s.io/backend created
[desk@cli] $ vim /home/cert_masters/frontend-pod.yaml
apiVersion: v1
kind: Pod
metadata:
name: frontend
spec:
serviceAccountName: backend-qa # Add this
image: nginx
name: frontend
[desk@cli] $ k apply -f /home/cert_masters/frontend-pod.yaml

質問 # 20
You are responsible for managing the software supply chain of a critical application deployed in a Kubernetes cluster. This application utilizes a library called 'lib-crypto' for secure cryptographic operations. How can you ensure that the version of 'lib-ctypto' deployed in your Kubernetes environment is the same as the one specified in the Software Bill of Materials (SBOM) for the application?
正解：
解説：
Solution (Step by Step) :
1. Obtain the SBOM: Retrieve the SBOM for your application. This document will contain a list of all the components and their versions, including 'lib- crypto'. The SBOM can be generated using various tools like 'cyclonedx-boms or 'Sbom-cli'.
2. Parse the S80M: IJse a suitable tool or script to parse the SdOM and extract the version of 'lib-crypto' from the S80M_
3. Verify in the Deployment Manifest: Inspect the deployment manifest for your application. Look for the container definition that uses the 'lib-crypto' image. Ensure that the image tag used in the deployment manifest matches the version of 'Iib-crypto' extracted from the SBOM_
4. Implement Image Scanning: Integrate an image scanning tool like 'Clair' or 'Anchores into your CI/CD pipeline. This will scan the 'Iib-crypto' image before deployment to ensure it doesn't contain any vulnerabilities or unexpected components.
5. Use a Container Registry with SBOM Support: Consider using a container registry like JFrog Xray or Snyk Container which supports storing and verifying S80Ms for each image. This provides a centralized mechanism for tracking and validating the software components in your container images.
