Kubernetes Misconfiguration: Kernel Defaults Overridden

YAML

Abstract

이 Kubelet 구성은 Kubelet이 커널 기본값을 재정의하는 것을 허용합니다.

Explanation

ProtectKernelDefaults 설정을 설정하지 않은 상태로 두거나 false로 설정하면 Kubelet이 런타임에 커널 매개 변수를 수정할 수 있습니다. Kubernetes 배포 전에 커널 매개 변수를 최적화하고 강화해야 합니다. Kubelet에 커널 매개 변수를 변경할 수 있는 권한을 부여하면 호스트 운영 체제의 공격 표면이 확장됩니다.

예제 1: 다음 Kubelet 구성은 ProtectKernelDefaults: false 설정으로 인해 Kubelet이 커널 매개 변수를 구성하는 것을 허용합니다.


apiVersion: kubelet.config.k8s.io/v1beta1
kind: KubeletConfiguration
ProtectKernelDefaults: false
