소프트웨어 보안은 보안 소프트웨어가 아닙니다. 여기서는 인증, 액세스 제어, 기밀성, 암호화, 권한 관리 등의 항목에 대해 설명합니다.

Kubernetes Misconfiguration: Missing PodSecurityPolicy Admission Controller

YAML

Abstract

Kubernetes API 서버를 시작하는 이 명령은 PodSecurityPolicy 승인 컨트롤러를 활성화하지 않습니다.

Explanation

PodSecurityPolicy 승인 컨트롤러가 없으면 K-Rail, Kyverno, OPA/Gatekeeper와 같은 Kubernetes용 대체 보안 적용 도구가 없을 경우 보안 제어가 취약함을 나타냅니다. PodSecurityPolicy 승인 컨트롤러는 클러스터에서 허용 가능한 보안 관련 Pod 속성을 지정하는 Pod 보안 정책을 적용합니다. 예를 들어 PodSecurityPolicy를 사용하면 Pod가 생성될 때마다 기본적으로 권한 있는 컨테이너를 금지하고 권한 에스컬레이션을 허용하지 않을 수 있습니다.

예제 1: 다음 Pod 정의는 PodSecurityPolicy 승인 컨트롤러를 활성화하지 않고 Kubernetes API 서버를 시작합니다.
