Ensure no duplicate user names exist

MediaNivel 1Automatizadafreebsd

Descripción

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.

Cómo se verifica

Método de auditoría: Comando de shell

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

Salida esperada: compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

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.
