보통레벨 1자동azure-container-linux

설명

Although the useradd program will not let you create a duplicate User ID (UID), it is possible for an administrator to manually edit the /etc/passwd file and change the UID field. Audit: Passes when no value of field 3 in /etc/passwd appears more than once.

조치 방식: 가이드 또는 인프라 패치
