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

Kubernetes Misconfiguration: Missing Kubelet Certificate Authentication

Abstract
Kubelet의 HTTPS 끝점에 대한 X509 클라이언트 인증서 인증이 정의되지 않았습니다.
Explanation
Kubelet은 클라이언트를 인증할 수 있지만 클라이언트 인증서를 확인하는 데 사용되는 CA(인증 기관) 번들이 Kubelet 구성에 정의되어 있지 않습니다. Kubelet은 작업자 시스템 워크로드를 관리하는 Kubernetes 주요 에이전트이기 때문에 공격자는 익명 요청을 사용하여 충분히 보호되지 않고 보안에 민감한 서비스 API에 액세스할 수 있습니다.

예제 1: 다음 Kubelet 구성은 클라이언트 인증서를 확인하는 데 사용되는 CA 번들을 지정하는 clientCAFile 필드를 포함하지 않습니다.
