최신 Kubernetes Security Specialist CKS 무료샘플문제 (Q65-Q70):

질문 # 65
A container image scanner is set up on the cluster.
Given an incomplete configuration in the directory
/etc/Kubernetes/confcontrol and a functional container image scanner with HTTPS endpoint https://acme.local.8081/image_policy

정답：A

설명：
2. Validate the control configuration and change it to implicit deny.
Finally, test the configuration by deploying the pod having the image tag as the latest.


질문 # 66
Your organization has a policy requiring all Kubernetes deployments to utilize Pod Security Policies (PSPs) to enforce security best practices. You're responsible for creating a PSP that enforces the following:
- Only allows containers with a specific security context (privileged: false, runAsUser: 1000, readOnlyRootFilesystem: true)
- Restricts access to most resources by denying the 'hostPort and 'hostNetwork' capabilities.
- Prohibits the use of privileged containers.
Implement the required PSP configuration

정답：

설명：
Solution (Step by Step) :
1. Create a PodSecurityPolicy:
- Define a PodSecurityP01icy named 'secure-policy' that enforces the specified security restrictions.

2. Create a PodSecurityPolicy8inding: - Bind the 'secure-policy' to a namespace or specific deployments. - This ensures that the PSP is enforced for deployments Within the bound scope.

3. Deploy the PSP: - Apply the 'secure-policy.yaml and 'secure-policy-binding.yaml files to the cluster - This will activate the PSP and enforce the defined security rules. 4. Validate PSP Enforcement - Attempt to create a deployment that violates the PSP rules. - Verifry that the deployment creation fails due to the PSP enforcement.


질문 # 67
You are tasked with ensuring the security of a Kubernetes cluster running a sensitive application. Describe now you would implement a "least privilege" principle for both users and service accounts in this cluster.

정답：

설명：
Solution (Step by Step) :
1. User Roles and Permissions:
- Define specific roles with minimal permissions for different user groups based on their responsibilities.
- For example, developers might have access to deploy applications, while operations team members might have access to manage resources.
- use RBAC (Role-Based Access Control) in Kubemetes to define roles and assign them to users.
2. Service Account Permissions:
- Create separate service accounts for each application or service in the cluster.
- Grant the service accounts only the necessary permissions to perform their specific tasks.
- Avoid using default service accounts with broad permissions.
- Employ the "principle ot least privilege" by defining minimal permissions for service accounts.
3. Pod Security Policies (PSPs):
- Implement PSPs to enforce security constraints on pods, restricting resources that they can access.
- Define PSPs to allow only specific container images, disable privileged containers, limit resource requests, and enforce other security controls.
- Consider using Pod Security Admission (PSA) as a replacement for PSPs in Kubernetes 1.25+.
4. Network Policies:
- Implement network policies to control network communication between pods and services.
- Define rules that allow only necessary traffic between pods, restricting any unnecessary or unauthorized connections.
5. Secret Management
- Utilize Kubernetes Secrets to store sensitive information like passwords and API keys.
- Limit access to secrets based on the principle of least privilege.
- Avoid storing sensitive information directly in deployment YAML files.


질문 # 68
You are running a Kubernetes cluster in AWS with a workload that involves sensitive data processing. You suspect that some of your pods might be compromised and are leaking data to an external server. You need to identify the compromised pods and isolate them from the network. Explain the steps you would take to achieve this, including the tools and techniques you would use to monitor network traffic, identify suspicious activity, and isolate compromised pods.

정답：

설명：
Solution (Step by Step):
1. Enable Network Policy: Start by enabling network policies in your Kubernetes cluster. This will restrict network traffic between pods based on predefined rules.
Implementation:

2. Monitor Network Traffic with tools like: Kubernetes Network Policy: Analyze the network policies configured on your cluster to identify any potentially suspicious traffic patterns. Kube-Proxy: Use 'kubectl proxy' to monitor the network traffic within your cluster. Observe incoming and outgoing traffic to identify any unusual patterns. Network Security Monitoring Tools: Consider using dedicated network security monitoring tools like Suricata, Zeek, or tcpdump for more comprehensive network analysis. Implementation: bash kubectl proxy --port=8001 # Start kubectl proxy # In a separate terminal, run the following command to view traffic to a specific pod: curl -v http://localhost.'8001/api/v1/namespaces/default/pods//proxy/ # Analyze the output to identify suspicious traffic. 3. Analyze Logs for Suspicious Activity: Kubernetes Logs: I-Ise tools like ' kubectl logs to inspect the logs of your pods, especially those related to data processing. Look for signs of unauthorized access, data exfiltration attempts, or unusual activity patterns. Security Logging: Configure your cluster to collect security-related events and logs in a centralized logging system like Elasticsearch, Fluentd, and Kibana (EFK) stack. Security Monitoring Tools: Employ tools like Falco or Auditd to actively monitor and analyze security-related events within your Kubernetes cluster. Implementation: bash kubectl logs -f # View logs of the pod 4. Isolate Compromised Pods: Network Segmentation: Use network policies to restrict the network access of suspected pods. Pod Disruption Budget (PDB): Ensure that your workload doesn't become unavailable during the isolation process. Service Disruption: If the compromised pod belongs to a service, consider temporarily removing it from the service's endpoint list to isolate the compromised service instance. Implementation:

5. Investigate and Remediate: Root Cause Analysis: Once the compromised pod is isolated, perform a thorough analysis to determine the cause of the compromise. This may involve examining system logs, network traffic, and potentially performing forensic analysis on the compromised pod Security Remediation: Address the root cause of the compromise by patching vulnerabilities, updating security configurations, and nardening your systems. Recovery and Restoration: If necessary, recover data that may have been leaked and restore your system to a secure state. Implementation: bash # Investigate the cause of the compromise: kubectl logs -f # Analyze the network traffic related to the pod using kubectl proxy and network monitoring tools. # Remediate the compromise: kubectl delete pod # Replace with the name of the compromised pod # Update security configurations # Patch vulnerabilities # Consider using a new container image with updated security measures # Restore data if necessary

Context:
Cluster: prod
Master node: master1
Worker node: worker1
You can switch the cluster/configuration context using the following command:
[desk@cli] $ kubectl config use-context prod
Task:
Analyse and edit the given Dockerfile (based on the ubuntu:18:04 image)
/home/cert_masters/Dockerfile fixing two instructions present in the file being prominent security/best-practice issues.
Analyse and edit the given manifest file
/home/cert_masters/mydeployment.yaml fixing two fields present in the file being prominent security/best-practice issues.
Note: Don't add or remove configuration settings; only modify the existing configuration settings, so that two configuration settings each are no longer security/best-practice concerns.
Should you need an unprivileged user for any of the tasks, use user nobody with user id 65535

정답：

설명：
1. For Dockerfile: Fix the image version & user name in Dockerfile
