Start Overview OF Cloud Native Security PracticeWhen managing Kubernetes clusters on Google Cloud Platform (GKE), Google manages the control plane infrastructure. Under the shared responsibility model, what is the customer primarily responsible for securing?
Explanation: In GKE's shared responsibility model, Google manages the control plane (including the API server, scheduler, controller manager, and etcd) as well as the physical infrastructure, hypervisors, and data center security. The customer is responsible for securing the worker nodes (which run the actual workloads) and the cluster configuration, such as network policies, RBAC, pod security, and node OS patching when using standard GKE nodes. This division is explicitly defined in Google Cloud's documentation: Google secures the infrastructure, while the customer secures what they deploy and how they configure it.
A platform engineering team is reviewing security layers for a newly provisioned Kubernetes cluster on AWS using Amazon EKS. Which layer of the 4Cs of Cloud Native Security encompasses patching the underlying Linux kernel of the worker nodes?
Explanation: In the 4Cs of Cloud Native Security (Cloud, Cluster, Container, Code), the Cluster layer encompasses the security of the Kubernetes cluster itself, including the control plane and worker nodes. Patching the underlying Linux kernel of the worker nodes is a cluster-level responsibility because it involves the host operating system that runs the container runtime and kubelet. Therefore, the Cluster layer is correct.
An organization adopts immutable infrastructure principles for their Kubernetes worker nodes. When a patch is required, they replace the entire node instance rather than updating packages in place. This practice primarily enhances security at which of the 4Cs layers?
Explanation: Immutable infrastructure for worker nodes maps to the Cluster layer of the 4Cs, because node lifecycle management—provisioning, patching by replacement, and decommissioning—is part of how the cluster infrastructure is built and maintained. Replacing rather than mutating nodes eliminates configuration drift and ensures every node conforms to a known-good, hardened image.
An organization is performing a threat modeling exercise for a Kubernetes cluster. They identify that an attacker could exploit a vulnerability in the container runtime (e.g., containerd) to access the underlying host. Which of the 4Cs does the container runtime belong to?
Explanation: The container runtime (e.g., containerd, CRI-O) is part of the Container layer in the 4Cs model. The 4Cs — Cloud, Cluster, Container, and Code — define layers of defense-in-depth, and the container runtime sits squarely in the Container layer because it directly manages container lifecycle, images, and isolation primitives (namespaces, cgroups, seccomp). A runtime escape vulnerability therefore represents a Container-layer failure that can compromise the host.
According to the shared responsibility model, when deploying a managed database service on cloud infrastructure, who is responsible for patching the database software and managing database user access control?
Explanation: For managed database services, the cloud provider typically patches the database engine software, while the customer manages user access, schemas, and data security. Wait, let's look at the options to align with standard cloud shared responsibility. Actually, database software patching is often managed by the provider in fully managed databases, but let's check customer responsibilities. Let's make sure the option is unambiguous.
