Ciao, professionista della tecnologia! Se <\/span>sei<\/span> un amministratore IT o lavori nell’ambito dei servizi gestiti (MSP), sai gi\u00e0 che mantenere l’ambiente sicuro \u00e8 una priorit\u00e0 assoluta. Un’area che spesso deve essere esaminata \u00e8 la configurazione di PowerShell sui sistemi Windows. Quindi, <\/span>iniziamo a<\/span> parlare di PowerShell 2.0 e del motivo per cui \u00e8 consigliabile disabilitarlo<\/strong>. O, ancora meglio, <\/span>iniziamo a<\/span> parlare di uno script che lavora al posto tuo per farlo.<\/span><\/span>\u00a0<\/span><\/p>\n

Perch\u00e9 disabilitare PowerShell 2.0?<\/h2>\n

In primo luogo, cerchiamo di capire perch\u00e9 dovresti voler disabilitare PowerShell 2.0. Questa versione legacy di PowerShell non dispone di molte delle funzioni di sicurezza e dei miglioramenti disponibili nelle versioni pi\u00f9 recenti. \u00c8 praticamente un invito aperto ai malintenzionati a sfruttare i tuoi sistemi.<\/span>\u00a0<\/span><\/p>\n

Lo script per disabilitare PowerShell 2.0<\/h2>\n

Ora che abbiamo stabilito il “perch\u00e9”, parliamo del “come”. Lo script per disabilitare PowerShell 2.0 \u00e8 una soluzione completa. Scritto in PowerShell 5.1, lo script \u00e8 progettato per funzionare su Windows 10, Windows Server 2016 e versioni successive.<\/span><\/p>\n

Ecco cosa offre questo script:<\/span><\/b>\u00a0<\/span><\/h3>\n

Controllo dei privilegi elevati<\/span><\/i>\u00a0<\/span><\/h4>\n

Lo script esegue un controllo iniziale per verificare se sia stato eseguito con privilegi amministrativi e, in caso contrario, ti notifica la necessit\u00e0 di essere lanciato da un amministratore.<\/span>\u00a0<\/span><\/p>\n

Controllo del sistema operativo e della versione<\/span><\/i>\u00a0<\/span><\/h4>\n

Prima di tentare di disabilitare PowerShell 2.0, lo script controlla la versione di PowerShell in uso. \u00c8 necessario eseguire PowerShell 5.1 o successivo. \u00c8 una funzionalit\u00e0 utile, che consente di non creare problemi alla configurazione esistente.<\/span>\u00a0<\/span><\/p>\n

La rimozione<\/span><\/i>\u00a0<\/span><\/h4>\n

Lo script utilizza diversi comandi (<\/span>Disable-WindowsOptionalFeature e Uninstall-WindowsFeature<\/span><\/i>) in base al sistema operativo in uso per disabilitare PowerShell 2.0. Se PowerShell 2.0 \u00e8 gi\u00e0 disabilitato, lo script te lo far\u00e0 sapere.<\/span>\u00a0<\/span><\/p>\n
