Lokale Verwaltungstools in Windows deaktivieren [PowerShell Script]

Achtung IT-Fachleute und Managed Service Provider (MSPs): Wenn Sie schon einmal mit der Aufrechterhaltung der Netzwerksicherheit und des administrativen Zugriffs betraut waren, wissen Sie, dass dies oft leichter gesagt als getan ist. Ein wichtiger Aspekt dabei ist die Verwaltung lokaler Administrator-Tools, über die die Benutzer:innen nicht frei verfügen sollten. Dies führt uns zu einer häufig gestellten Frage: Wie deaktiviere ich lokale Verwaltungstools bei der Skalierung?

Wir haben ein umfassendes PowerShell-Skript, mit dem Sie die Verwaltungstools in einer Windows-Umgebung selektiv deaktivieren können.

Das PowerShell-Skript „Lokale Admin-Tools deaktivieren

#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.

    PS C:> .Disable-LocalAdminTools.ps1 -Tools "MMC,Cmd,TaskMgr,RegistryEditor"
    Disabling MMC...

Wie das Skript funktioniert

Das Skript, das wir hier besprechen, ist in PowerShell geschrieben und dient dazu, bestimmte Verwaltungstools auf lokalen Computern zu deaktivieren. Es wurde für die Arbeit mit PowerShell 5.1 optimiert und bietet verschiedene auswählbare Optionen wie Eingabeaufforderung, Systemsteuerung, Microsoft Management Console (MMC), Registrierungseditor, Befehlsfenster und Task-Manager. Sie können entweder alle diese Tools deaktivieren oder aus einer durch Kommata getrennten Liste auswählen, um nur bestimmte Tools zu deaktivieren.

Außerdem bietet das Skript die Möglichkeit, bestimmte Benutzerprofile von dieser Aktion auszuschließen. Wenn Sie sicherstellen müssen, dass einige Benutzer:innen ihre Verwaltungsfunktionen beibehalten, können Sie dies problemlos tun.

Dieses PowerShell-Skript führt drei wichtige Überprüfungen durch:

  1. Überprüft, ob das Skript mit administrativen Rechten ausgeführt wird.
  2. Lädt die Registrierungsschlüssel für jedes Benutzerprofil, mit Ausnahme derjenigen, die ausdrücklich ausgeschlossen sind.
  3. Ändert oder setzt Registrierungsschlüssel, um die ausgewählten Verwaltungstools zu deaktivieren.

Es geht nicht nur um die Deaktivierung, sondern auch um Kontrolle und Spezifität, was dieses Skript für IT-Administratoren und MSPs sehr vielseitig macht.

Warum IT-Fachleute und MSPs sich darum kümmern sollten

Zentralisierte Kontrolle

Mithilfe dieses PowerShell-Skripts können IT-Experten lokale Verwaltungstools zentral deaktivieren, was den Zeitaufwand für die manuelle Deaktivierung für jeden einzelnen Benutzer erheblich verringert.

Sicherheit

Die Deaktivierung dieser Tools erhöht die Sicherheit, da sie die Möglichkeiten der Benutzer:innen, Änderungen auf Systemebene vorzunehmen, einschränkt. Dies ist besonders in Umgebungen nützlich, in denen Sie potenzielle Sicherheitsrisiken von innen heraus minimieren möchten.

Vielseitigkeit

Die Fähigkeit des Skripts, Tools selektiv zu deaktivieren und bestimmte Benutzer:innen auszuschließen, verleiht ihm eine Flexibilität, die für unterschiedliche IT-Umgebungen maßgeschneidert ist. Es ist keine Einheitsgröße, sondern eine Einheitsgröße, die passt, wie Sie es wollen.

Automatisierung und Skalierbarkeit

Für MSPs kann das Skript in automatisierte Bereitstellungsprozesse integriert werden, wodurch es für große Netzwerke skalierbar ist. Stellen Sie sich vor, Sie könnten dies mit wenigen Klicks auf Tausende von Rechnern ausweiten.

Wie wird es eingesetzt?

Laden Sie einfach das Skript Disable-LocalAdminTools.ps1 herunter und führen Sie es über PowerShell auf den Zielcomputern aus. Das Skript unterstützt verschiedene Befehlszeilenoptionen zur Feinabstimmung dessen, was Sie deaktivieren möchten.

PS C:>.Disable-LocalAdminTools.ps1 -Tools „MMC,Cmd,TaskMgr,RegistryEditor“

Abschließende Überlegungen

Ganz gleich, ob Sie als IT-Experte nach einer Lösung zum Deaktivieren lokaler Administratortools oder als MSP nach einem einfach zu implementierenden Skript zum Deaktivieren von Administratortools suchen, dieses PowerShell-Skript bietet eine robuste, flexible und effiziente Lösung. Es macht aus der Komplexität eine Einfachheit und gibt Ihnen mehr Kontrolle über die Sicherheitseinstellungen Ihres Netzwerks.

Mit diesem effizienten, zielgerichteten Ansatz für den administrativen Zugriff sind Sie dem Wettbewerb immer einen Schritt voraus. Viel Spaß beim Schreiben!
