Cet article vous aide à désactiver certains protocoles pour réussir les analyses de conformité de l'industrie des cartes de paiement (PCI) à l'aide de Windows® PowerShell®.
Le bloc de script suivant inclut des éléments qui désactivent les mécanismes d'affaiblissement du chiffrement à l'aide de modifications du registre. Voir les commentaires du bloc de script pour plus de détails. Après avoir exécuté n'importe quel élément du script, vous devez redémarrer le serveur Windows pour appliquer pleinement les modifications.
