最新的 Kubernetes Security Specialist CKS 免費考試真題 (Q44-Q49):

問題 #44
Fix all issues via configuration and restart the affected components to ensure the new setting takes effect.
Fix all of the following violations that were found against the API server:- a. Ensure the --authorization-mode argument includes RBAC b. Ensure the --authorization-mode argument includes Node c. Ensure that the --profiling argument is set to false Fix all of the following violations that were found against the Kubelet:- a. Ensure the --anonymous-auth argument is set to false.
b. Ensure that the --authorization-mode argument is set to Webhook.
Fix all of the following violations that were found against the ETCD:-
a. Ensure that the --auto-tls argument is not set to true
Hint: Take the use of Tool Kube-Bench

答案：

解題說明：
API server:
Ensure the --authorization-mode argument includes RBAC
Turn on Role Based Access Control. Role Based Access Control (RBAC) allows fine-grained control over the operations that different entities can perform on different objects in the cluster. It is recommended to use the RBAC authorization mode.

Ensure the --authorization-mode argument includes Node
Remediation: Edit the API server pod specification file /etc/kubernetes/manifests/kube-apiserver.yaml on the master node and set the --authorization-mode parameter to a value that includes Node.
--authorization-mode=Node,RBAC
Audit:
/bin/ps -ef | grep kube-apiserver | grep -v grep
Expected result:
'Node,RBAC' has 'Node'
Ensure that the --profiling argument is set to false
Remediation: Edit the API server pod specification file /etc/kubernetes/manifests/kube-apiserver.yaml on the master node and set the below parameter.
--profiling=false
Audit:
/bin/ps -ef | grep kube-apiserver | grep -v grep
Expected result:
'false' is equal to 'false'
Fix all of the following violations that were found against the Kubelet:- Ensure the --anonymous-auth argument is set to false.
Remediation: If using a Kubelet config file, edit the file to set authentication: anonymous: enabled to false. If using executable arguments, edit the kubelet service file /etc/systemd/system/kubelet.service.d/10-kubeadm.conf on each worker node and set the below parameter in KUBELET_SYSTEM_PODS_ARGS variable.
--anonymous-auth=false
Based on your system, restart the kubelet service. For example:
systemctl daemon-reload
systemctl restart kubelet.service
Audit:
/bin/ps -fC kubelet
Audit Config:
/bin/cat /var/lib/kubelet/config.yaml
Expected result:
'false' is equal to 'false'
2) Ensure that the --authorization-mode argument is set to Webhook.
Audit
docker inspect kubelet | jq -e '.[0].Args[] | match("--authorization-mode=Webhook").string' Returned Value: --authorization-mode=Webhook Fix all of the following violations that were found against the ETCD:- a. Ensure that the --auto-tls argument is not set to true Do not use self-signed certificates for TLS. etcd is a highly-available key value store used by Kubernetes deployments for persistent storage of all of its REST API objects. These objects are sensitive in nature and should not be available to unauthenticated clients. You should enable the client authentication via valid certificates to secure the access to the etcd service.

問題 #45
You're in charge of enforcing a secure supply chain in your Kubernetes environment. You need to ensure that all container images deployed to your cluster are scanned for known vulnerabilities before being deployed. How would you achieve this?

答案：

解題說明：
Solution (Step by Step) :
1. Choose a Vulnerability Scanner:
- Select a reputable container image vulnerability scanner. Popular options include:
- Aqua Security: A comprehensive platform that offers image scanning, runtime security, and policy enforcement.
- JFrog Xray: A vulnerability scanner that integrates with JFrog Artifactory, providing deep scanning capabilities.
- Ancnore Engine: An open-source scanner that can be deployed on-premises or in the Cloud.
2. Integrate with Your Registry (if applicable):
- If your vulnerability scanner support integration with your registry (e.g., Docker Hub, Harbor), configure it to scan images automatically as they are pushed.
- This approach provides real-time vulnerability scanning, ensuring that only secure images are available for deployment.
3. Implement a Scanning Pipeline (if needed):
- If your chosen scanner doesn't integrate with your registry, build a scanning pipeline using a CI/CD tool like Jenkins, GitLab Cl, or CircleCl.
- The pipeline should:
- Pull the image from the registry.
- Run the vulnerability scanner against the image.
- Fail the build if any critical vulnerabilities are found.
- If no critical vulnerabilities are found, push the scanned image to the registry with a tag indicating its scan status.
4. Configure Kubernetes Policies:
- Use Kubernetes policies (like Pod Security Policies or Admission Controllers) to enforce the following:
- Restrict deployments to images with a "scanned" tag: This ensures only images that have undergone vulnerability scanning are deployed.
- Block deployments of images with known critical vulnerabilities: This prevents deployment of images with unacceptable risks.
5. Monitor Scanning Results:
- Continuously monitor vulnerability scanning results.
- Keep track of vulnerabilities found and their severity.
- Update your policies to reflect changes in vulnerability scanning results.
6. Remediation and Patching:
- Have a process in place to remediate and patch vulnerabilities found in images.
- Work with developers and security teams to address vulnerabilities promptly.


問題 #46
SIMULATION
Use the kubesec docker images to scan the given YAML manifest, edit and apply the advised changes, and passed with a score of 4 points.
kubesec-test.yaml
apiVersion: v1
kind: Pod
metadata:
name: kubesec-demo
spec:
containers:
- name: kubesec-demo
image: gcr.io/google-samples/node-hello:1.0
securityContext:
readOnlyRootFilesystem: true
Hint: docker run -i kubesec/kubesec:512c5e0 scan /dev/stdin < kubesec-test.yaml

答案：A


問題 #47
You are tasked with implementing a security policy that prohibits the use of privileged containers in your Kubernetes cluster. Implement a solution that uses KubeLinter to enforce this policy by automatically scanning all deployments and preventing deployments that violate the policy.

答案：

解題說明：
Solution (Step by Step):
1. Install KubeLinter: Download and install the 'kubevar binary from the official GitHub repository.
2. Create a custom KubeLinter check: Define a custom check that prohibits the use of privileged containers. This check can be defined in a separate
YAML file or embedded in your '.kubeval.yaml configuration file.

3. Configure KubeLinter to use the custom check: Add the custom check to your .kuoeval.yaml configuration file.

4. Integrate KubeLinter into your CI/CD pipeline: Add a step to your pipeline that runs KubeLinter against your deployment YAML manifests. This step should be executed before the manifests are deployed to the cluster.

5. (Optional) Implement an admission controller: For real-time enforcement, deploy an admission controller that uses KubeLinter to validate deployments as they are created or updated. This will prevent any deployments that violate the policy from being created in the cluster. Tools like Kyverno or Gatekeeper can be used to create and enforce such policies.


問題 #48
Context
A container image scanner is set up on the cluster, but it's not yet fully integrated into the cluster s configuration. When complete, the container image scanner shall scan for and reject the use of vulnerable images.
Task

Given an incomplete configuration in directory /etc/kubernetes/epconfig and a functional container image scanner with HTTPS endpoint https://wakanda.local:8081 /image_policy :
1. Enable the necessary plugins to create an image policy
2. Validate the control configuration and change it to an implicit deny
3. Edit the configuration to point to the provided HTTPS endpoint correctly Finally, test if the configuration is working by trying to deploy the vulnerable resource /root/KSSC00202/vulnerable-resource.yml.
