界: Security Features

ソフトウェアのセキュリティは、セキュリティソフトウェアではありません。ここでは、認証、アクセス制御、機密性、暗号化、権限管理などのトピックについて説明します。

Kubernetes Misconfiguration: Missing Security Context

YAML

Abstract

コンテナーにセキュリティコンテキストがありません。

Explanation

最小特権の原則に準拠した、詳細な権限を定義することをお勧めします。Kubernetes セキュリティコンテキストは、コンテナーまたは Pod の権限とアクセス制御設定を定義します。Pod レベルとコンテナーレベルの両方にそのような設定がない場合、コンテナーにはセキュリティコンテキストがありません。

例 1: 次の構成では、セキュリティコンテキストなしで Pod を定義します。これは、securityContext フィールドがないためです。


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