Ensure no duplicate UIDs exist

보통레벨 1자동freebsd

설명

Although the adduser or pw program will not let you create a duplicate User ID (UID), an administrator can manually edit the /etc/passwd file and change the UID field. Users must be assigned unique UIDs for accountability and to ensure appropriate access protections. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.

점검 방법

감사 방식: 셸 명령

shell

command -v cut >/dev/null 2>&1 || exit 1; out=$( { cut -d: -f3 /etc/passwd | sort -n | uniq -d ; } 2>/dev/null ); [ -z "$out" ] && echo compliant || printf '%s\n' "$out" | head -n 20

예상 출력: compliant

조치 방법

조치 방식: 가이드 또는 인프라 패치

Based on the audit script's results, establish unique UIDs and review all files owned by the shared UIDs to determine which UID they are supposed to belong to.
