Ensure no duplicate GIDs exist

MittelStufe 1Automatisiertfreebsd

Beschreibung

Although the pw program will not let you create a duplicate Group ID (GID), it is possible for an administrator to manually edit the /etc/group file and change the GID field. User groups must be assigned unique GIDs 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=$( { cut -d: -f3 /etc/group | sort -n | uniq -d ; } 2>/dev/null ); [ -z "$out" ] && echo compliant || printf '%s\n' "$out" | head -n 20

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