Linux Foundation KCSA 考試大綱：

主題簡介
主題 1
  • 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.
主題 2
  • Platform Security: This section of the exam measures the skills of a Cloud Security Architect and encompasses broader platform-wide security concerns. This includes securing the software supply chain from image development to deployment, implementing observability and service meshes, managing Public Key Infrastructure (PKI), controlling network connectivity, and using admission controllers to enforce security policies.
主題 3
  • 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.
主題 4
  • 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.
主題 5
  • Kubernetes Threat Model: This section of the exam measures the skills of a Cloud Security Architect and involves identifying and mitigating potential threats to a Kubernetes cluster. It requires understanding common attack vectors like privilege escalation, denial of service, malicious code execution, and network-based attacks, as well as strategies to protect sensitive data and prevent an attacker from gaining persistence within the environment.

最新的 Kubernetes and Cloud Native KCSA 免費考試真題 (Q12-Q17):

問題 #12
In the event that kube-proxy is in a CrashLoopBackOff state, what impact does it have on the Pods running on the same worker node?

答案：C

解題說明：
* kube-proxy:manages cluster network routing rules (via iptables or IPVS). It enables Pods to communicate with Services and Pods across nodes.
* If kube-proxy fails (CrashLoopBackOff), service IP routing and cluster-wide pod-to-pod networking breaks. Local Pod-to-Pod communication within the same node may still work, butcross-node communication fails.
* Exact extract (Kubernetes Docs - kube-proxy):
* "kube-proxy maintains network rules on nodes. These rules allow network communication to Pods from network sessions inside or outside of the cluster." References:
Kubernetes Docs - kube-proxy: https://kubernetes.io/docs/reference/command-line-tools-reference/kube- proxy/


問題 #13
Which other controllers are part of the kube-controller-manager inside the Kubernetes cluster?

答案：D

解題說明：
* kube-controller-managerruns a set of controllers that regulate the cluster's state.
* Exact extract (Kubernetes Docs):"The kube-controller-manager runs controllers that are core to Kubernetes. Examples of controllers are: Node controller, Replication controller, Endpoints controller, Namespace controller, and ServiceAccounts controller."
* Why D is correct:All listed are actual controllers within kube-controller-manager.
* Why others are wrong:
* A:Job and CronJob controllers are managed by kube-controller-manager, but DaemonSet controller is managed by the kube-scheduler/deployment logic.
* B:Pod, Service, Ingress controllers are not part of kube-controller-manager.
* C:ConfigMap and Secret do not have dedicated controllers.

Kubernetes Docs - kube-controller-manager: https://kubernetes.io/docs/reference/command-line-tools- reference/kube-controller-manager/


問題 #14
In which order are thevalidating and mutating admission controllersrun while the Kubernetes API server processes a request?

答案：A

解題說明：
* Theadmission control flowin Kubernetes:
* Mutating admission controllersrun first and can modify incoming requests.
* Validating admission controllersrun after mutations to ensure the final object complies with policies.
* This ensures policies validate thefinal, mutated object.

Kubernetes Documentation - Admission Controllers
CNCF Security Whitepaper - Admission control workflow.


問題 #15
A container running in a Kubernetes cluster has permission to modify host processes on the underlying node.
What combination of privileges and capabilities is most likely to have led to this privilege escalation?

答案：C

解題說明：
* hostPID:When enabled, the container shares the host's process namespace # container can see and potentially interact with host processes.
* SYS_PTRACE capability:Grants the container the ability to trace, inspect, and modify other processes (e.g., via ptrace).
* Combination of hostPID + SYS_PTRACE allows a container toattach to and modify host processes, which is a direct privilege escalation.
* Other options explained:
* hostPath + AUDIT_WRITE:hostPath exposes filesystem paths but does not inherently allow process modification.
* hostNetwork + NET_RAW:grants raw socket access but only for networking, not host process modification.
* A:Incorrect - such combinationsdo exist(like B).

Kubernetes Docs - Configure a Pod to use hostPID: https://kubernetes.io/docs/tasks/configure-pod-container
/share-process-namespace/
Linux Capabilities man page: https://man7.org/linux/man-pages/man7/capabilities.7.html


問題 #16
Which of the following statements best describes the role of the Scheduler in Kubernetes?

答案：B

解題說明：
* 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).
