Abstract
已停用串流連線的閒置逾時。
Explanation
Kubelet 組態的 streamingConnectionIdleTimeout 欄位指定在連線自動關閉之前,串流連線閒置的最長時間。設定閒置逾時可以防止 Denial of Service 攻擊及耗盡所有連線。將欄位值設定為 0 會停用閒置逾時。

範例 1:以下 Kubelet 組態透過將 streamingConnectionIdleTimeout 欄位設定為 0 來停用串流連線逾時。

apiVersion: kubelet.config.k8s.io/v1beta1
kind: KubeletConfiguration
streamingConnectionIdleTimeout: 0

Abstract
Kubernetes API 伺服器對於要求不需要任何授權。
Explanation
Kubernetes API 伺服器可使用多種授權模式之一來授權要求。API 伺服器在 AlwaysAllow 模式下不會執行任何授權,因為這個模式允許所有要求。

範例 1:以下組態將啟動一部 Kubernetes API 伺服器,並使用 AlwaysAllow 做為授權模式之一。

...
kind: Pod
...
spec:
containers:
- command:
- kube-apiserver
...
- --authorization-mode=...,AlwaysAllow,...

Abstract
當 Pod 建立 SSL 連線時會停用 API 伺服器身分驗證。
Explanation
Kubernetes Controller Manager 在沒有 --root-ca-file 旗標的情況下啟動,此時會指定根憑證授權單位 (CA) 檔案。所以,Kubernetes Controller Manager 不會將對應的根 CA 憑證發佈至 Pod。若沒有根 CA 憑證,Pod 就無法在建立連線之前驗證 API 伺服器的服務憑證。這樣的連線容易遭到 man-in-the-middle 攻擊。

範例 1:以下組態將在沒有 --root-ca-file 旗標的情況下啟動一個 Kubernetes Controller Manager。

Abstract
未指定對已終止 Pod 啟用垃圾回收的閾值。
Explanation
當已終止 Pod 的數量超過閾值時,Kubernetes 控制器就會起始垃圾回收來回收這些 Pod 佔用的資源。雖然垃圾回收過度會降低效能,但預設閾值 12500 對於典型叢集來說過高。在發生任何垃圾回收之前,叢集可能會因資源不足而變得不穩定。

範例 1:以下組態將啟動一個 Kubernetes Controller Manager 而不指定旗標。

Abstract
Kubelet 對於要求不需要任何授權。
Explanation
Kubelet 使用 AlwaysAllow 模式或 Webhook 模式授權要求。如未指定授權模式,將預設為 AlwaysAllow。Kubelet 在 AlwaysAllow 模式下不會執行任何授權檢查,因為這個模式允許所有要求。由於 Kubelet 是管理工作者機器工作負載的 Kubernetes 主要代理程式,所以攻擊者可使用未控制的要求來存取保護不足和安全性敏感的服務 API。

範例 1:Kubelet 不進行任何授權檢查,因為授權模式設定為 AlwaysAllow

Abstract
未定義對 Kubelet 的 HTTPS 端點進行 X509 用戶端憑證驗證。
Explanation
Kubelet 可以對用戶端進行驗證,但用於驗證用戶端憑證的憑證授權單位 (CA) 組合並未定義於 Kubelet 組態。由於 Kubelet 是用於管理背景工作機器工作負載的 Kubernetes 主要代理程式,所以攻擊者可使用匿名要求來存取保護不足和安全性敏感的服務 API。

範例 1:以下 Kubelet 組態不包含 clientCAFile 欄位,此欄位指定用於驗證用戶端憑證的 CA 組合。

Abstract
Kubernetes API 伺服器不會向 Kubelet 的 HTTPS 端點驗證自己的身分。
Explanation
依預設,Kubernetes API 伺服器在提交要求時不會向 Kubelet 驗證自己的身分。若 Kubelet 提供對各種資源的存取,將無法驗證這些要求的真實性。

範例 1:以下指令將啟動 Kubernetes API 伺服器,但未分別利用 --kubelet-client-certificate 旗標和 --kubelet-client-key 旗標指定用戶端憑證和對應私密金鑰,來啟用對 Kubelet 進行以憑證為基礎的驗證。

Abstract
當 Kubernetes API 伺服器建立 SSL 連線時,Kubelet 的伺服器身分驗證會停用。
Explanation
Kubernetes API 伺服器傳送指令給 Kubelet 以建立工作負載、查詢 Kubelet 管理之資源的狀態,並為 Kubelet 提供選用的連接埠轉送服務。依預設,API 伺服器在建立連線之前不會驗證 Kubelet 的服務憑證。此連線因而容易遭到 man-in-the-middle 攻擊。

範例 1:以下指令將啟動 Kubernetes API 伺服器,而不指定根憑證組合來利用 --kubelet-certificate-authority 旗標驗證 Kubelet 的服務憑證。

Abstract
Kubernetes API 伺服器不使用 Node 模式來授權 Kubelet 發出的要求。
Explanation
Kubernetes API 伺服器可使用多種授權模式之一來授權要求。Node 授權是一種特殊用途的授權模式,專門用於授權 Kubelet 發出的 API 要求。這可確保 Kubelet 擁有正確操作所需的最少權限組。

範例 1:以下組態將啟動一部 Kubernetes API 伺服器,而不使用 Node 授權模式。

Abstract
啟動 Kubernetes API 伺服器的指令不會啟用 NodeRestriction 准入控制器。
Explanation
請始終為 Kubernetes API 伺服器啟用 NodeRestriction 准入控制器。NodeRestriction 准入控制器會限制每個 Kubelet 修改其 Node 和 Pod 物件,也會拒絕存取敏感系統物件。如此一來,即可防止任何遭到入侵的節點在 Kubernetes 叢集的其他節點上獲得特權。

範例 1:以下 Pod 定義在不啟用 NodeRestriction 准入控制器的情況下啟動 Kubernetes API 伺服器。

Abstract
啟動 Kubernetes API 伺服器的指令不會啟用 PodSecurityPolicy 准入控制器。
Explanation
缺乏 PodSecurityPolicy 准入控制器表示安全性控制較弱,除非有用於 Kubernetes 的替代原則強制執行工具,例如 K-Rail、Kyverno、OPA/Gatekeeper。PodSecurityPolicy 准入控制器會強制執行 Pod 安全性原則,這些原則指定叢集中許可的安全性相關 Pod 屬性。例如,您可以使用 PodSecurityPolicy 預設在每次建立 Pod 時禁用具有特權的容器並禁止提升特權。

範例 1:以下 Pod 定義在不啟用 PodSecurityPolicy 准入控制器的情況下啟動 Kubernetes API 伺服器。

Abstract
Container 缺少安全性環境。
Explanation
較好的做法是根據最小特權原則來定義精細的權限。Kubernetes 安全性環境定義 Container 或 Pod 的特權和存取控制設定。如果 Pod 和 Container 層級都沒有這類的設定,則 Container 會缺少安全性環境。

範例 1:以下組態定義一個沒有任何安全性環境的 Pod,這是因為沒有 securityContext 欄位。

apiVersion: v1
kind: Pod
...
spec:
containers:
- name: web
image: nginx
ports:
- name: web
containerPort: 80
protocol: TCP

Abstract
未指定用於簽署服務帳戶權杖的私密金鑰。
Explanation
Kubernetes API 伺服器可以透過服務帳戶權杖對 API 要求進行驗證。這類權杖由 Kubernetes 權杖控制器產生並簽署。請使用 --service-account-private-key-file 標誌來指定權杖簽署金鑰。

範例 1:以下組態將在沒有 --service-account-private-key-file 旗標的情況下啟動一個 Kubernetes Controller Manager。

apiVersion: v1
kind: Pod
...
spec:
containers:
- command:
- kube-controller-manager

Abstract
啟動 Kubernetes API 伺服器的指令會停用 ServiceAccount 准入控制器。
Explanation
Kubernetes 將使用者帳戶與服務帳戶的概念區分開來,目的是為了讓處理程序在 Pod 中執行。ServiceAccount 准入控制器會自動執行服務帳戶管理。ServiceAccount 准入控制器有幾項優點,包括透過自動化認證輪換來減輕存取權杖洩露問題,並消除將密鑰存留在儲存空間中的必要。ServiceAccount 准入控制器預設為啟用,但已被蓄意停用。

範例 1:以下 Pod 定義會啟動 Kubernetes API 伺服器並停用 ServiceAccount 准入控制器。

apiVersion: v1
kind: Pod
...
spec:
containers:
- command:
- kube-apiserver
...
- --disable-admission-plugins=ServiceAccount,PodNodeSelector

Abstract
Kubernetes API 伺服器中的 NamespaceLifecycle 准入控制器已停用。
Explanation
若刪除 Kubernetes 命名空間,將會移除該命名空間中的所有物件,包括 Pod 和服務在內。NamespaceLifecycle 准入控制器使用兩種方式維護 Kubernetes 系統的完整性。第一種方式是防止在不存在的名稱空間或正在終止的名稱空間中建立物件。第二種方式是防止系統保留的命名空間 (其包含 Kubernetes 關鍵服務) 被刪除。

NamespaceLifecycle 准入控制器預設為啟用,但啟動 Kubernetes API 伺服器的指令已利用 --disable-admission-plugin 旗標將其停用。

範例 1:以下組態將啟動 Kubernetes API 伺服器。如果 NamespaceLifecycle 包含在 --disable-admission-plugins 旗標中,就會停用 NamespaceLifecycle 准入控制器。

...
kind: Pod
...
spec:
containers:
- command:
- kube-apiserver

- --disable-admission-plugins=...,NamespaceLifecycle,...

Abstract
etcd 執行個體會接受來自使用自行簽署憑證之對等端的 TLS 連線。
Explanation
Kubernetes 將敏感資料保存在 etcd 叢集中。因此,每個 etcd 執行個體都應該僅接受來自已驗證且獲授權之對等端的連線,並拒絕任何使用自行簽署憑證進行 TLS 連線的對等端。

範例 1:以下組態將啟動一個 etcd 執行個體,並將 --peer-auto-tls 旗標設定為 true。因此,etcd 執行個體會使用自行簽署憑證與對等端進行 TLS 連線。

...
spec:
containers:
- command:
...
- etcd
...
- --peer-auto-tls=true

Abstract
Kubernetes 容器可以在特權模式下執行。
Explanation
依預設,系統會拒絕 Kubernetes 容器存取主機上的所有裝置。privileged 欄位允許容器與主機上執行的其他處理程序具有幾乎所有相同權限。這會擴大受攻擊面,違反以最小權限執行映像的原則。

範例 1:Pod 透過設定 privileged: true 以特權模式執行。
