Cloud NAT Service: Use Cloud NAT (Network Address Translation) to allow VM instances without external IP addresses to access the internet securely.

Configuration: Configure Cloud NAT for the subnets containing your VM instances. This setup allows the VMs to initiate outbound connections to the internet for updates and other necessary communications.

Security Compliance: By using Cloud NAT, you adhere to the security policy of not assigning external IP addresses to VMs while still enabling necessary internet connectivity. Cloud NAT provides a secure method for outbound internet traffic without exposing VMs directly to the public internet. References:

Google Cloud Directory Sync (GCDS): Install and configure GCDS to synchronize your on-premises Active Directory with Google Cloud Identity. This tool helps in maintaining consistency between your local directory and Google Cloud.

IAM Groups: Create IAM groups in Google Cloud with permissions that correspond to your Active Directory groups. This mapping ensures that users inherit the appropriate permissions based on their AD group membership.

Synchronization: Set up regular synchronization schedules to keep the user and group information up-to-date between your on-premises AD and Google Cloud.

Access Management: Use these IAM groups to manage access to Google Cloud resources, ensuring that permissions are applied consistently and securely. This approach leverages existing AD infrastructure for identity management, providing a seamless integration with Google Cloud. References:

When a vulnerability patch is released for a running container in Google Kubernetes Engine (GKE), the recommended approach is to update the application code or apply the patch directly to the codebase. Then, a new container image should be built incorporating these changes. After building the new image, it should be deployed to replace the running containers. This method ensures that the containers run the updated, secure code.

Steps:

Update Application Code: Modify the application code or dependencies to incorporate the vulnerability patch.

Build New Image: Use a tool like Docker to build a new container image with the updated code.

Push New Image: Push the new container image to the Container Registry.

Update Deployments: Update the Kubernetes deployment to use the new image. This can be done by modifying the image tag in the deployment YAML file.

Redeploy Containers: Apply the updated deployment configuration using kubectl apply -f <deployment-file>.yaml, which will redeploy the containers with the new image.

Uniform bucket-level access allows you to manage permissions at the bucket level, rather than at the object level. This simplifies permission management and ensures that access to objects is controlled consistently via IAM roles, without allowing uploaders full control over the objects.

Steps:

Enable Uniform Bucket-Level Access: In the Google Cloud Console, enable uniform bucket-level access for the Cloud Storage bucket.

Configure IAM Policies: Assign appropriate IAM roles to users and groups to control access to the bucket.

Audit Logging: Enable Cloud Audit Logs to track access and modifications to the bucket.
