질문 # 57
You have a Kubernetes cluster that runs a sensitive application called "banking-app" in a Deployment The application needs access to a private registry to pull container images. You want to ensure that the "banking-app" container only communicates with the private registry and no other external networks. How can you use NetworkPolicy to enforce this network security restriction?

정답：

설명：
Solution (Step by Step) :
1. Create a NetworkPolicy tor the Private Registry: You'll create a NetworkPolicy that allows the "banking-app" container to communicate with the private registry but blocks access to all other external networks.

'podSelectors: This defines which pods are affected by the policy. - 'policyTypeS: This specifies the type of traffic that the policy governs (Ingress in this case). - 'ingress': Defines the allowed incoming traffic. - 'trom': Specifies the source of allowed traffic. - spodSeIector': Allows traffic from other pods with the "banking-app" label. - 'ipBlock': Allows traffic from a specific CIDR range. - 'cidr': Replace '172.17.0.0/16' with the actual CIDR of your private registry. - 'except': Optional for excluding specific IP addresses or ranges. 2 Apply the NetworkPolicy: Apply the YAML file to your cluster: bash kubectl apply -f banking-app-registry-access.yaml 3. Verify NetworkPolicy: After applying the policy, run: bash kubectl get networkpolicy -n default # Replace 'default' with your namespace You should see your new "banking-app-registry-access" NetworkPolicy listed. 4. Test the Policy: - Try to access external networks from within the "banking-app" container. - You should observe that the container is unable to connect to any external services except the private registry. - Make sure your application can still pull images from the private registry. 5. Additional Considerations: - Egress Traffic: You might need to define a separate NetworkPolicy for 'Egress' traffic if you want to allow the "banking-app" to communicate with specific internal services. - Detailed Controls: You can add more specific rules to the 'ingress' section to allow specific ports or protocols from the private registry.


질문 # 58
SIMULATION

Context
AppArmor is enabled on the cluster's worker node. An AppArmor profile is prepared, but not enforced yet.

Task
On the cluster's worker node, enforce the prepared AppArmor profile located at /etc/apparmor.d/nginx_apparmor.
Edit the prepared manifest file located at /home/candidate/KSSH00401/nginx-pod.yaml to apply the AppArmor profile.
Finally, apply the manifest file and create the Pod specified in it.

질문 # 59
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 that the RotateKubeletServerCertificate argument is set to true.
b. Ensure that the admission control plugin PodSecurityPolicy is set.
c. Ensure that the --kubelet-certificate-authority argument is set as appropriate.
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
b. Ensure that the --peer-auto-tls argument is not set to true
Hint: Take the use of Tool Kube-Bench

질문 # 60
You're tasked With securing a Kubernetes cluster for a sensitive application. The application utilizes a service account for accessing a database. However, due to legacy reasons, this service account has broad permissions, including 'read', 'write', and 'delete' access to all resources in the cluster. How would you mitigate this security risk while maintaining application functionality? Implement a solution that minimizes the permissions granted to the service account and adheres to the principle of least privilege.

정답：

설명：
Solution (Step by Step) :
1. Create a new Role With restricted permissions:
- Define a Role that grants only the necessary permissions for the service account to interact with the database.
- The Role should have specific permissions for 'read' , 'write' , and 'delete' operations, but limited to the database resources used by the application.

2. Create a RoleBinding: - Bind the newly created Role to the service account. - This will grant the service account the specific permissions defined in the Role.

3. Update the Deployment - Update the Deployment configuration to use the new service account with restricted permissions.

4. Validate the Permissions: - Verity that the application still functions correctly with the restricted permissions. - Use 'kubectl auth can-i --list --as=your-service-account' to confirm the available permissions for the service account. 5. Revoke the Legacy Service Account: - Once the application is running with the new service account, revoke the old service account with broad permissions.
