Check for Duplicate UIDs

MediaNivel 1Automatizadasolaris

Descripción

Although the useradd program will not let you create a duplicate User ID (UID), it is possible for an administrator to manually modify passwd 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.

Cómo se verifica

Método de auditoría: Comando de shell

shell

command -v logins >/dev/null 2>&1 || exit 1; out=$( { logins -d ; } 2>/dev/null ); [ -z "$out" ] && echo compliant || printf '%s\n' "$out" | head -n 20

Salida esperada: compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

Correct or justify any items discovered in the Audit step. Determine if there exists any users who share a common UID, and work with those users to determine the best course of action in accordance with site policy.
