Ensure no duplicate UIDs exist

SedangLevel 1Otomatisfreebsd

Deskripsi

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.

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

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.
