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
  • 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.
トピック 2
  • 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.
トピック 3
  • 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 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.
トピック 5
  • Compliance and Security Frameworks: This section of the exam measures the skills of a Compliance Officer and focuses on applying formal structures to ensure security and meet regulatory demands. It covers working with industry-standard compliance and threat modeling frameworks, understanding supply chain security requirements, and utilizing automation tools to maintain and prove an organization's security posture.

Linux Foundation Kubernetes and Cloud Native Security Associate 認定 KCSA 試験問題 (Q29-Q34):質問 # 29
Which of the following represents a baseline security measure for containers?
  • A. Run containers as the root user.
  • B. Configuring a static IP for each container.
  • C. Configuring persistent storage for containers.
  • D. Implementing access control to restrict container access.
正解：D
解説：
* Access control (RBAC, least privilege, user restrictions)is abaseline container security best practice.
* Exact extract (Kubernetes Pod Security Standards - Baseline):
* "The baseline profile is designed to prevent known privilege escalations. It prohibits running privileged containers or containers as root."
* Other options clarified:
* B: Static IPs not a security measure.
* C: Persistent storage is functionality, not security.
* D: Running as root is explicitlyinsecure.

質問 # 30
Why mightNetworkPolicyresources have no effect in a Kubernetes cluster?
  • A. NetworkPolicy resources are only enforced if the Kubernetes scheduler supports them.
  • B. NetworkPolicy resources are only enforced for unprivileged Pods.
  • C. NetworkPolicy resources are only enforced if the networking plugin supports them.
  • D. NetworkPolicy resources are only enforced if the user has the right RBAC permissions.
正解：C
解説：
* NetworkPolicies define how Pods can communicate with each other and external endpoints.
* However, Kubernetes itselfdoes not enforce NetworkPolicy. Enforcement depends on theCNI plugin used (e.g., Calico, Cilium, Kube-Router, Weave Net).
* If a cluster is using a network plugin that does not support NetworkPolicies, then creating NetworkPolicy objects hasno effect.

Kubernetes Documentation - Network Policies
CNCF Security Whitepaper - Platform security section: notes that security enforcement relies on CNI capabilities.

質問 # 31
What is the purpose of the Supplier Assessments and Reviews control in the NIST 800-53 Rev. 5 set of controls for Supply Chain Risk Management?
  • A. To conduct regular audits of suppliers' financial performance.
  • B. To identify potential suppliers for the organization.
  • C. To evaluate and monitor existing suppliers for adherence to security requirements.
  • D. To establish contractual agreements with suppliers.
正解：C
解説：
* In NIST SP 800-53 Rev. 5,SR-6: Supplier Assessments and Reviewsrequires evaluating and monitoring suppliers' security and risk practices.
* Exact extract (NIST SP 800-53 Rev. 5, SR-6):
* "The organization assesses and monitors suppliers to ensure they are meeting the security requirements specified in contracts and agreements."
* This is aboutongoing monitoringof supplier adherence, not financial audits, not contract creation, and not supplier discovery.

質問 # 32
As a Kubernetes and Cloud Native Security Associate, a user can set upaudit loggingin a cluster. What is the risk of logging every event at the fullRequestResponselevel?
  • A. Reduced storage requirements and faster performance.
  • B. Increased storage requirements and potential impact on performance.
  • C. No risk, as it provides the most comprehensive audit trail.
  • D. Improved security and easier incident investigation.
正解：B
解説：
* Audit loggingrecords API server requests and responses for security monitoring.
* TheRequestResponse levellogs the full request and response bodies, which can:
* Significantly increasestorage and performance overhead.
* Potentially log sensitive data (including Secrets).
* Therefore, while comprehensive, it introduces risks of performance degradation and excessive log volume.

質問 # 33
In a Kubernetes cluster, what are the security risks associated with using ConfigMaps for storing secrets?
  • A. ConfigMaps store sensitive information in etcd encoded in base64 format automatically, which does not ensure confidentiality of data.
  • B. Storing secrets in ConfigMaps can expose sensitive information as they are stored in plaintext and can be accessed by unauthorized users.
  • C. Using ConfigMaps for storing secrets might make applications incompatible with the Kubernetes cluster.
  • D. Storing secrets in ConfigMaps does not allow for fine-grained access control via RBAC.
正解：B
解説：
* ConfigMaps are explicitly not for confidential data.
* Exact extract (ConfigMap concept):"A ConfigMap is an API object used to store non- confidential data in key-value pairs."
* Exact extract (ConfigMap concept):"ConfigMaps are not intended to hold confidential data. Use a Secret for confidential data."
* Why this is risky:data placed into a ConfigMap is stored as regular (plaintext) string values in the API and etcd (unless you deliberately use binaryData for base64 content you supply). That means if someone has read access to the namespace or to etcd/APIServer storage, they can view the values.
* Secrets vs ConfigMaps (to clarify distractor D):
* Exact extract (Secret concept):"By default, secret data is stored as unencrypted base64- encoded strings.You canenable encryption at restto protect Secrets stored in etcd."
* This base64 behavior applies toSecrets, not to ConfigMap data. Thus optionDis incorrect for ConfigMaps.
* About RBAC (to clarify distractor A):Kubernetesdoessupport fine-grained RBAC forboth ConfigMaps and Secrets; the issue isn't lack of RBAC but that ConfigMaps arenotdesigned for confidential material.
* About compatibility (to clarify distractor C):Using ConfigMaps for secrets doesn't make apps
"incompatible"; it's simplyinsecureand against guidance.
References:
Kubernetes Docs -ConfigMaps: https://kubernetes.io/docs/concepts/configuration/configmap/ Kubernetes Docs -Secrets: https://kubernetes.io/docs/concepts/configuration/secret/ Kubernetes Docs -Encrypting Secret Data at Rest: https://kubernetes.io/docs/tasks/administer-cluster
/encrypt-data/
Note: The citations above are from the official Kubernetes documentation and reflect the stated guidance that ConfigMaps are fornon-confidentialdata, while Secrets (with encryption at rest enabled) are forconfidential data, and that the 4C's map todefense in depth.
