Linux Foundation KCSA 認定試験の出題範囲：

トピック出題範囲
トピック 1
  • Kubernetes Security Fundamentals: This section of the exam measures the skills of a Kubernetes Administrator and covers the primary security mechanisms within Kubernetes. This includes implementing pod security standards and admissions, configuring robust authentication and authorization systems like RBAC, managing secrets properly, and using network policies and audit logging to enforce isolation and monitor cluster activity.
トピック 2
  • Kubernetes Cluster Component Security: This section of the exam measures the skills of a Kubernetes Administrator and focuses on securing the core components that make up a Kubernetes cluster. It encompasses the security configuration and potential vulnerabilities of essential parts such as the API server, etcd, kubelet, container runtime, and networking elements, ensuring each component is hardened against attacks.
トピック 3
  • Overview of Cloud Native Security: This section of the exam measures the skills of a Cloud Security Architect and covers the foundational security principles of cloud-native environments. It includes an understanding of the 4Cs security model, the shared responsibility model for cloud infrastructure, common security controls and compliance frameworks, and techniques for isolating resources and securing artifacts like container images and application code.

Linux Foundation Kubernetes and Cloud Native Security Associate 認定 KCSA 試験問題 (Q61-Q66):

質問 # 61
Which of the following statements on static Pods is true?

正解：D

解説：
* Static Podsare managed directly by thekubeleton each node.
* They arenot scheduled by the kube-schedulerand always remain bound to the node where they are defined.
* Exact extract (Kubernetes Docs - Static Pods):
* "Static Pods are managed directly by the kubelet daemon on a specific node, without the API server. They do not go through the Kubernetes scheduler."
* Clarifications:
* A: Static Pods do not span multiple nodes.
* B: No hard limit of 5 Pods per node.
* D: They are not a fallback mechanism; kubelet always manages them regardless of scheduler state.

質問 # 62
Which of the following statements best describes the role of the Scheduler in Kubernetes?

正解：A

解説：
* TheKubernetes Schedulerassigns Pods to nodes based on:
* Resource requests & availability (CPU, memory, GPU, etc.)
* Constraints (affinity, taints, tolerations, topology, policies)
* Exact extract (Kubernetes Docs - Scheduler):
* "The scheduler is a control plane process that assigns Pods to Nodes. Scheduling decisions take into account resource requirements, affinity/anti-affinity, constraints, and policies."
* Other options clarified:
* A: Monitoring cluster health is theController Manager's/kubelet's job.
* B: Security is enforced throughRBAC, admission controllers, PSP/PSA, not the scheduler.
* C: Deployment scaling is handled by theController Manager(Deployment/ReplicaSet controller).

質問 # 63
A container image istrojanizedby an attacker by compromising the build server. Based on the STRIDE threat modeling framework, which threat category best defines this threat?

正解：C

解説：
* In STRIDE,Tamperingis the threat category forunauthorized modification of data or code/artifacts. A trojanized container image is, by definition, an attacker'smodificationof the build output (the image) after compromising the CI/build system-i.e., tampering with the artifact in the software supply chain.
* Why not the others?
* Spoofingis about identity/authentication (e.g., pretending to be someone/something).
* Repudiationis about denying having performed an action without sufficient audit evidence.
* Denial of Servicetargets availability (exhausting resources or making a service unavailable).The scenario explicitly focuses on analtered imageresulting from a compromised build server-this squarely maps toTampering.
Authoritative references (for verification and deeper reading):
* Kubernetes (official docs)- Supply Chain Security (discusses risks such as compromised CI/CD pipelines leading to modified/poisoned images and emphasizes verifying image integrity/signatures).
* Kubernetes Docs#Security#Supply chain securityandSecuring a cluster(sections on image provenance, signing, and verifying artifacts).
* CNCF TAG Security - Cloud Native Security Whitepaper (v2)- Threat modeling in cloud-native and software supply chain risks; describes attackers modifying build outputs (images/artifacts) via CI
/CD compromise as a form oftamperingand prescribes controls (signing, provenance, policy).
* CNCF TAG Security - Software Supply Chain Security Best Practices- Explicitly covers CI/CD compromise leading tomaliciously modified imagesand recommends SLSA, provenance attestation, and signature verification (policy enforcement via admission controls).
* Microsoft STRIDE (canonical reference)- DefinesTamperingasmodifying data or code, which directly fits a trojanized image produced by a compromised build system.


質問 # 64
Given a standard Kubernetes cluster architecture comprising a single control plane node (hosting bothetcdand the control plane as Pods) and three worker nodes, which of the following data flows crosses atrust boundary
?

正解：B

解説：
* Trust boundariesexist where data flows between different security domains.
* In Kubernetes:
* Communication between thekubelet (node agent)and theAPI Server (control plane)crosses the node-to-control-plane trust boundary.
* (A) Kubelet to container runtime is local, no boundary crossing.
* (C) Kubelet does not communicate directly with the controller manager.
* (D) API server does not talk directly to the container runtime; it delegates to kubelet.
* Therefore, (B) is the correct trust boundary crossing flow.
References:
CNCF Security Whitepaper - Kubernetes Threat Model: identifies node-to-control-plane communications (kubelet # API Server) as crossing trust boundaries.
Kubernetes Documentation - Cluster Architecture


質問 # 65
What does thecluster-adminClusterRole enable when used in a RoleBinding?

正解：B

解説：
* Thecluster-adminClusterRole is asuperuser rolein Kubernetes.
* Binding it (via RoleBinding or ClusterRoleBinding) grantsunrestricted control over all resources in the cluster, across all namespaces.
* This includes management of cluster-scoped resources (nodes, CRDs, RBAC rules) and namespace- scoped resources.
* Therefore, cluster-admin is equivalent toroot-level accessin Kubernetes and must be used with extreme caution.
References:
Kubernetes Documentation - Default Roles and Role Bindings
CNCF Security Whitepaper - Identity and Access Management: cautions against assigningcluster-admin broadly due to its unrestricted nature.
