Attention aux professionnels de l’informatique et aux fournisseurs de services gérés (MSP) : si vous avez été chargé de maintenir la sécurité du réseau et l’accès administratif, vous savez que c’est souvent plus facile à dire qu’à faire. Un aspect essentiel est la gestion des outils d’administrateur local que les utilisateurs ne devraient pas pouvoir utiliser librement. Cela nous amène à une question souvent posée : Comment désactiver les outils d’administration locale à grande échelle ?
Nous avons un script PowerShell complet qui vous permet de désactiver les outils d’administration de votre choix dans un environnement Windows.
Le script PowerShell de désactivation des outils d’administration locale
#Requires -Version 5.1 <# .SYNOPSIS This will disable the selected administrator tools depending on your selection (Defaults to all). Can be given a comma separated list of users to exclude from this action. .DESCRIPTION This will disable the selected administrator tools. The options are "All", the command prompt, the control panel, the microsoft management console, the registry editor, the run command window and task manager. You can give it a comma separated list of items if you want to disable some but not all. Exit 1 is usually an indicator of bad input but can also mean editing the registry is blocked. .EXAMPLE PS C:> .Disable-LocalAdminTools.ps1 -Tools "MMC,Cmd,TaskMgr,RegistryEditor" Disabling MMC...

Comment fonctionne le script
Le script dont nous parlons est écrit en PowerShell et est conçu pour désactiver des outils d’administration spécifiques sur des machines locales. Il a été optimisé pour fonctionner avec PowerShell 5.1 et propose plusieurs options sélectionnables telles que l’Invite de commande, le Panneau de configuration, la Console de gestion Microsoft (MMC), l’Éditeur de registre, la Fenêtre d’exécution des commandes et le Gestionnaire des tâches. Vous pouvez désactiver tous ces outils ou choisir dans une liste séparée par des virgules de ne désactiver que certains d’entre eux.
De plus, le script permet d’exclure certains profils utilisateur de cette action. Si vous devez vous assurer que certains utilisateurs conservent leurs capacités d’administration, vous pouvez le faire facilement.
Ce script PowerShell effectue trois validations importantes :
- Vérifie si le script est exécuté avec des privilèges administrateur.
- Charge les clés de registre pour chaque profil utilisateur, à l’exception de celles qui sont explicitement exclues.
- Modifie ou définit les clés de registre pour désactiver les outils d’administration sélectionnés.
Il ne s’agit pas seulement de désactivation, mais aussi de contrôle et de spécificité, ce qui rend ce script très polyvalent pour les administrateurs informatiques et les MSP.
Pourquoi c’est important pour les professionnels de l’informatique et les MSP
Contrôle centralisé
En utilisant ce script PowerShell, les professionnels de l’informatique peuvent désactiver les outils d’administration locaux de manière centralisée, sans avoir besoin de le faire manuellement pour chaque utilisateur.
Sécurité
La désactivation de ces outils renforce la sécurité en limitant la capacité des utilisateurs à apporter des modifications au niveau du système. Ceci est particulièrement utile dans les environnements où l’on souhaite minimiser les risques potentiels de sécurité à l’intérieur de l’entreprise.
Polyvalence
La capacité du script à désactiver sélectivement des outils et à exclure des utilisateurs spécifiques lui confère une flexibilité adaptée à divers environnements informatiques. Il ne s’agit pas d’une solution unique, mais d’une solution adaptée à la façon dont vous voulez agir.
Automatisation et évolutivité
Pour les MSP, le script peut être intégré dans des processus de déploiement automatisés, ce qui le rend évolutif pour les grands réseaux. Imaginez la facilité avec laquelle vous pouvez déployer ce système sur des milliers de machines en quelques clics.
Comment le déployer
Il suffit de télécharger le script Disable-LocalAdminTools.ps1 et de l’exécuter via PowerShell sur les machines cibles. Le script prend en charge diverses options de ligne de commande pour affiner ce que vous souhaitez désactiver.
PS C :>.Disable-LocalAdminTools.ps1 -Tools « MMC,Cmd,TaskMgr,RegistryEditor »
Conclusions
Que vous soyez un professionnel de l’informatique à la recherche d’une solution pour désactiver les outils d’administration locaux ou une entreprise MSP à la recherche d’un script de désactivation des outils d’administration facile à déployer, ce script PowerShell fournit une solution fiable, flexible et efficace. Il transforme la complexité en simplicité, en vous donnant plus de contrôle sur les paramètres de sécurité de votre réseau.
Gardez une longueur d’avance en adoptant cette approche efficace et ciblée de l’accès administratif. Bon codage !
