Ensure no duplicate user names exist

보통레벨 1자동freebsd

설명

Although the adduser or pw program will not let you create a duplicate user name, it is possible for an administrator to manually edit the /etc/passwd file and change the username. If a user is assigned a duplicate user name, it will create and have access to files with the first UID for that username in /etc/passwd. 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=$( { cut -d: -f1 /etc/passwd | sort | uniq -d ; } 2>/dev/null ); [ -z "$out" ] && echo compliant || printf '%s\n' "$out" | head -n 20

예상 출력: compliant

조치 방법

조치 방식: 가이드 또는 인프라 패치

Establish unique user names for the users based on the audit script's results. As long as the users have unique UIDs, file ownership will automatically reflect the change.
