CKS 인증 시험은 컨테이너 보안, Kubernetes API 보안, 네트워크 보안, 접근 제어, 감사 및 로깅 등 보안 관련 주제를 다룹니다. 후보자들은 Kubernetes 보안 개념을 확실하게 이해해야 하며, Kubernetes 배포를 보호하고 보안 정책을 구현하며 보안 위험을 관리하는 방법을 알아야 합니다. 또한, kube-bench, kube-hunter 등 Kubernetes 보안 도구를 사용하여 보안 취약점을 식별하고 완화하는 능력을 증명해야 합니다. 전반적으로, CKS 인증 시험은 전문가들이 Kubernetes 보안 기술을 향상시키고 이 경쟁이 치열한 분야에서 전문성을 증명하는 데 탁월한 방법입니다.
질문 # 51
Context
A default-deny NetworkPolicy avoids to accidentally expose a Pod in a namespace that doesn't have any other NetworkPolicy defined.
Task
Create a new default-deny NetworkPolicy named defaultdeny in the namespace testing for all traffic of type Egress.
The new NetworkPolicy must deny all Egress traffic in the namespace testing.
Apply the newly created default-deny NetworkPolicy to all Pods running in namespace testing.

질문 # 52
You have a Kubernetes cluster with a custom admission controller that enforces certain security policies. You need to write a script that can be used to test the functionality of the admission controller by creating a Pod With specific properties that should be rejected by the controller.
정답:
설명:
Solution (Step by Step) :
1. Define tne admission controller policy:
- Assume the admission controller is configured to reject Pods that are not running in a specific namespace, like 'secure-namespace
2. Create a test Pod YAML file:
3. Write a Python script to create the Pod and check the result
4. Run the script: - Save the script as . - Execute the script using 'python test _ admission_controller.py' 5. Verify the results: - You should see the output indicating that the pod creation was rejected by the admission controller.
질문 # 53
You are deploying a Kubernetes cluster in a public cloud environment and are considering using a managed container registry service offered by the Cloud provider. What are the security considerations you Should take into account before Choosing a managed container registry service?
정답:
설명:
Solution (Step by Step) :
1. Data Security: Ensure that the managed container registry service has strong encryption mechanisms in place for data at rest and in transit Verity if they support encryption keys managed by you or if they provide their own key management service.
2. Access Control and Authentication: Check the service's access control policies and authentication mechanisms. Verify if you can enforce granular access permissions for different users and roles and whether you can integrate with your existing identity management systems.
3. Vulnerability Scanning: Determine if the managed container registry service includes built-in vulnerability scanning capabilities. If not, consider using third-pany tools that can integrate with the service.
4. Compliance and Certification: Evaluate whether the managed container registry service complies with relevant security standards and certifications, such as ISO 27001, SOC 2, or PCl DSS.
5. Service Availability: Consider the service's availability and redundancy guarantees. Evaluate the providers SLAS for uptime and performance.
6. Auditing and Logging: Check it the managed container registry service provides comprehensive auditing and logging features to track access patterns and identify potential security breaches.
7. Data Residency and Sovereignty: If you have data residency or sovereignty requirements, ensure that the managed container registry service can fulfill those requirements.
8. Open Source Components: Review the open-source components used by the managed container registry service. Ensure that these components are regularly updated and patched to mitigate security risks.
9. Data Backup and Recovery: Determine how data backups are handled. Ensure that you have access to backups and a clear recovery plan.

Secrets stored in the etcd is not secure at rest, you can use the etcdctl command utility to find the secret value for e.g:- ETCDCTL_API=3 etcdctl get /registry/secrets/default/cks-secret --cacert="ca.crt" --cert="server.crt" --key="server.key" Output
Using the Encryption Configuration, Create the manifest, which secures the resource secrets using the provider AES-CBC and identity, to encrypt the secret-data at rest and ensure all secrets are encrypted with the new configuration.
정답:
설명:
See the Explanation belowExplanation:
ETCD secret encryption can be verified with the help of etcdctl command line utility.
ETCD secrets are stored at the path /registry/secrets/$namespace/$secret on the master node.
The below command can be used to verify if the particular ETCD secret is encrypted or not.
# ETCDCTL_API=3 etcdctl get /registry/secrets/default/secret1 [...] | hexdump -C

Documentation
Deployment, Pod Security Admission, Pod Security Standards
You must connect to the correct host . Failure to do so may result in a zero score.
[candidate@base] $ ssh cks000036
Context
For compliance, all user namespaces enforce the restricted Pod Security Standard .
Task
The confidential namespace contains a Deployment that is not compliant with the restricted Pod Security Standard . Thus, its Pods can not be scheduled.
Modify the Deployment to be compliant and verify that the Pods are running.
The Deployment's manifest file can be found at /home/candidate/nginx-unprivileged.yaml.
정답:
설명:
See the Explanation below for complete solution
Explanation:
1) Connect to the correct host
ssh cks000036
sudo -i
export KUBECONFIG=/etc/kubernetes/admin.conf
2) Confirm the failing Pods + see the PSA error (fast)
kubectl -n confidential get deploy
kubectl -n confidential get pods
kubectl -n confidential describe deploy <deployment-name> | sed -n '/Events/,$p' (You'll usually see "violates PodSecurity 'restricted' ..." with the exact missing fields.)
3) Edit the provided manifest
vi /home/candidate/nginx-unprivileged.yaml
You must ensure the Pod template becomes compliant. Add/ensure the following exact blocks:
4) Add Pod-level securityContext (under spec.template.spec)
Find:
spec:
template:
spec:
Add this block under it (or merge if securityContext: already exists):
securityContext:
runAsNonRoot: true
runAsUser: 65535
seccompProfile:
type: RuntimeDefault
5) Add Container-level securityContext (under the nginx container)
Find:
containers:
- name: ...
image: ...
Under that container, add (or adjust) this exact block:
securityContext:
allowPrivilegeEscalation: false
readOnlyRootFilesystem: true
capabilities:
drop:
- ALL
If there are multiple containers, apply the same container securityContext to each one.
Save and exit:
:wq
6) Apply the manifest to the confidential namespace
kubectl -n confidential apply -f /home/candidate/nginx-unprivileged.yaml Wait rollout:
kubectl -n confidential rollout status deployment/<deployment-name>
If you don't know the deployment name from the file, list:
kubectl -n confidential get deploy
7) Verify Pods are running
kubectl -n confidential get pods -o wide
If still failing, show the exact PSA violation (this tells you what else to fix):
kubectl -n confidential describe pod <pod-name> | sed -n '/Events/,$p'
Quick "if it still fails" fixes (common restricted blockers)
Open the manifest again and ensure these are NOT set (or are removed/false):
hostNetwork: true
hostPID: true
hostIPC: true
any hostPort:
privileged: true
capabilities.add:
seccompProfile: Unconfined
runAsUser: 0 or runAsNonRoot: false
Then re-apply.
Minimal compliant result (what the grader expects)
Your Pod template should include:
seccompProfile: RuntimeDefault
runAsNonRoot: true (and a non-root UID like 65535)
container: allowPrivilegeEscalation: false
container: capabilities.drop: [ALL]
container: readOnlyRootFilesystem: true
