You can switch the cluster/configuration context using the following command: [desk@cli] $ kubectl config use-context dev A default-deny NetworkPolicy avoid to accidentally expose a Pod in a namespace that doesn't have any other NetworkPolicy defined.
Task: Create a new default-deny NetworkPolicy named deny-network in the namespace test for all traffic of type Ingress + Egress The new NetworkPolicy must deny all Ingress + Egress traffic in the namespace test.
Apply the newly created default-deny NetworkPolicy to all Pods running in namespace test.
You can find a skeleton manifests file at /home/cert_masters/network-policy.yaml

正解:A
質問 # 67
You have a Kubernetes cluster with a sensitive workload running in a specific namespace. You need to restrict access to this namespace to only authorized users- How would you achieve this using Role-Based Access Control (RBAC)?
正解:
解説:
Solution (Step by Step):
1. Create a Role: Define a Role that grants only the required permissions to access the sensitive namespace.
- Name: 'namespace-access-role' (you can choose any name)
- Namespace: The namespace you want to restrict access to.
- Rules:
- Resources: Specify the resources that the role allows access to. For example, 'pods", 'deployments', 'services', etc.
- Verbs: Define the allowed actions on tne resources. For example, 'get', 'list, 'watch', 'create', 'update' , 'delete', etc.
- ApiGroups: Specify the API group that the resources belong to. For example, 'apps', 'extensions' , etc.
- You can use wildcards to grant access to all resources or all verbs.
2. Create a ROIeBinding: Associate the Role with specific users or groups.
- Name: 'namespace-access-binding' (you can choose any name)
- Namespace: The namespace you want to restrict access to.
_ RoleRef-.
- Kind: 'Role' (since you are using a Role)
- Name: The name of the Role you created.
- ApiGroup: 'rbac.authorization.k8s.i0'
- Subjects: Define the users or groups that should have access to this Role.
- Kind: Specify whether it's a user or group.
- Name: The username or group name.
- ApiGroup: 'rbac.authorization.k8s.io'
3. Apply the Role and Role3inding:
- Use 'kubectl apply -f role.yaml' and 'kubectl apply -f rolebinding.yamr to create the Role and RoleBinding respectively
Example YAML for Role and Role8inding:
Role (role-yaml)
Role8inding (rolebinding.yaml)
- The Role 'namespace-access-role' grants permissions to access 'deployments' , 'pods' , 'services', and 'secrets' in the - The RoleBinding 'namespace-access-binding' associates this Role with the user - This setup Will restrict access to the namespace to only tne user Important Notes: - R8AC is a powerful mechanism to control access to resources in Kubernetes- - It's important to understand the different RBAC components (Role, RoleBinding, ClusterRole, ClusterRole8inding) and their usage. - Define granular permissions to ensure least privilege access and enhance security.
質問 # 68
You are running a Kubernetes cluster with a deployment named "my-app" that uses a container image from a public registry. The container image has a vulnerability in a library it uses. You want to prevent any container from using that vulnerable image. How would you implement this using a container image registry and admission control policies?
正解:
解説:
Solution (Step by Step) :
1. Create a Custom Container Image Registry:
- Create a private container image registry, such as Harbor, JFrog Xray, or GitLab Container Registry to manage your container images and enforce security policies.
2. Configure Image Scanning and Policies:
- Set up image scanning in your chosen registry to automatically scan incoming images for vulnerabilities. Configure policies to block images with specific vulnerabilities or based on severity levels.
3. Set up Admission Control Policies:
- Configure Kubernetes admission control to enforce image scanning and registry-based access control.
- Use admission webhooks to intercept pod creation requests and verify that the container image used in the pod is authorized.
- For example, you can create an admission webhook that checks if the image is stored in your private registry and has passed vulnerability scanning.
If the image is not in the registry or has known vulnerabilities, the webhook will deny the pod creation.
4. Deploy the Vulnerability-Free Image:
- Update the container image used by your "my-app" deployment with a patched or vulnerability-free version. Push this updated image to your private registry.
5. Update the Deployment
- Update the "my-app" deployment configuration to pull the container image from your private registry.
6. Monitor and Evaluate:
- Monitor the logs of your container image registry and Kubernetes admission controller for any errors or blocked images. Regularly review the vulnerability scan reports for any new vulnerabilities.
