Ensure no duplicate user names exist

中レベル 1自動freebsd

説明

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.

チェック方法

監査方法: シェルコマンド

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

期待される出力: compliant

修正方法

修正方法: ガイダンスまたは IaC パッチ

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.
