RKE2 CIS 1.6 Benchmark - 自我评估指南 - Rancher 2.6

CIS 1.6 Kubernetes Benchmark - Rancher 2.6 RKE2 与 Kubernetes 1.21 到 1.23

点击此处下载本文档的 PDF 版本。

概述

本文档是 Rancher 2.6 RKE2 安全强化指南的配套文件。强化指南（Hardening Guide）为通过 RKE2 配置集群的 Rancher 强化生产安装提供了说明，本 Benchmark 指南旨在帮助你根据 Benchmark 来评估强化集群的安全级别。

本指南对应以下强化指南、Rancher、CIS Benchmark 和 Kubernetes 版本：

强化指南版本Rancher 版本CIS Benchmark 版本Kubernetes 版本
强化指南 CIS v1.6 BenchmarkRancher v2.6.5+CIS v1.6Kubernetes v1.21 到 v1.23

由于 Rancher 和 RKE2 将 Kubernetes 服务安装为容器，因此 CIS Kubernetes Benchmark 中的许多管控验证检查都不适用，且结果会是 Not Applicable。本指南将介绍各种管控，并提供更新的示例命令来审核 Rancher 创建的集群的合规性。

本文档供 Rancher 开发、安全团队、审计员和决策者使用。

有关各个审核的更多详细信息，包括失败测试的理由和修正措施，你可以参考 CIS Kubernetes Benchmark v1.6 的对应内容。创建免费帐户后，你可以在 Center for Internet Security (CIS) 下载 Benchmark。

测试管控方法

RKE2 将 controlplane 组件作为由 kubelet 管理的静态 pod 启动，并使用 containerd 作为容器运行时。配置是通过初始化时传递给容器的参数或配置文件定义的。

如果管控审计与原始 CIS Benchmark 出现差异，针对 Rancher 提供的的审计命令可用于进行测试。执行测试时，你需要访问所有 RKE2 节点主机上的命令行。这些命令还使用了测试和评估测试结果所需的 kubectl（带有有效的配置文件）和 jq 工具。

1.2.27确保 —service-account-lookup 参数设置为 true（自动）

结果：pass

修正措施： 在 Master 节点上编辑 API Server pod 规范文件 /var/lib/rancher/rke2/agent/pod-manifests/kube-apiserver.yaml 并设置以下参数。 —service-account-lookup=true

你也可以删除此文件的 —service-account-lookup 参数，从而使默认设置生效。
