Linux Foundation KCSA 考試大綱：

主題簡介
主題 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.
主題 2
  • 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 3
  • 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.
主題 4
  • 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.

最新的 Kubernetes and Cloud Native KCSA 免費考試真題 (Q40-Q45):

問題 #40
Which information does a user need to verify a signed container image?

答案：A

解題說明：
* Container image signing (e.g., withcosign, Notary v2) uses asymmetric cryptography.
* Verification process:
* Retrieve theimage's digital signature.
* Validate the signature with thepublic keyof the signer.
* Exact extract (Sigstore Cosign Docs):
* "Verification of an image requires the signature and the signer's public key. The signature proves authenticity and integrity."
* Why others are wrong:
* A & B: The private key is only used by the signer, never shared.
* C: The hash alone cannot prove authenticity without the digital signature.

問題 #41
Which of the following is a control for Supply Chain Risk Management according to NIST 800-53 Rev. 5?

答案：D

解題說明：
* NIST SP 800-53 Rev. 5 introduces a dedicated family of controls calledSupply Chain Risk Management (SR).
* Within SR,SR-2 (Supply Chain Risk Management Plan)is a specific control.
* Exact extract from NIST 800-53 Rev. 5:
* "The organization develops and implements a supply chain risk management plan for the system, system component, or system service."
* While Access Control, System and Communications Protection, and Incident Response are control families, the correctsupply chain-specific controlis theSupply Chain Risk Management Plan (SR-2).

問題 #42
What was the name of the precursor to Pod Security Standards?

答案：C

解題說明：
* Kubernetes originally had a feature calledPodSecurityPolicy (PSP), which provided controls to restrict pod behavior.
* Official docs:
* "PodSecurityPolicy was deprecated in Kubernetes v1.21 and removed in v1.25."
* "Pod Security Standards (PSS) replace PodSecurityPolicy (PSP) with a simpler, policy- driven approach."
* PSP was often complex and hard to manage, so it was replaced by Pod Security Admission (PSA) which enforcesPod Security Standards.

問題 #43
To restrict the kubelet's rights to the Kubernetes API, whatauthorization modeshould be set on the Kubernetes API server?

答案：A

解題說明：
* TheNode authorization modeis designed to specifically limit what kubelets can do when they connect to the Kubernetes API server.
* It authorizes requests from kubelets based on the Pods scheduled to run on their nodes, ensuring kubelets cannot interact with resources beyond their scope.
* Incorrect options:
* (B)AlwaysAllowallows unrestricted access (insecure).
* (C) No kubelet authorization mode exists.
* (D)Webhookmode delegates authorization decisions to an external service, not specifically for kubelets.

問題 #44
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：B

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).
