Il Server Message Block Protocol (SMB) esiste da tempo ed \u00e8 una sorta di spina dorsale per la condivisione di file e per varie altre operazioni di rete. <\/span>Tuttavia, la prima versione, SMBv1, \u00e8 oggi considerata un problema a causa delle numerose vulnerabilit\u00e0 di sicurezza.<\/span> Se <\/span>sei<\/span> un professionista IT o un fornitore di servizi gestiti (MSP), la sicurezza della rete dovrebbe essere la tua preoccupazione principale. Quindi, come puoi disabilitare SMBv1<\/strong> in modo efficace?<\/span><\/p>\n

Cosa fa la script?<\/h2>\n

Questo script PowerShell \u00e8 stato progettato in modo <\/span>molto specifico<\/span> per uno scopo: disabilitare SMBv1 negli ambienti Windows. Funziona utilizzando una sequenza di cmdlet PowerShell integrati e modifiche del Registro di sistema per garantire che SMBv1 sia completamente disabilitato. Lo script per disabilitare SMBv1 pu\u00f2 essere eseguito in ambiente Windows 10 o Windows Server 2016 o successivo, il che lo rende estremamente versatile e prezioso per qualsiasi sistema Windows moderno.<\/span><\/p>\n
