Les scripts PowerShell jouent un r\u00f4le inestimable dans les op\u00e9rations et la s\u00e9curit\u00e9 informatiques, en automatisant des t\u00e2ches et en extrayant des informations vitales \u00e0 des fins d’analyse. Aujourd’hui, nous allons nous pencher sur un script qui vous permet d’afficher l’historique des connexions des utilisateurs,<\/strong> une fonction importante pour l’audit et le contr\u00f4le de l’acc\u00e8s au syst\u00e8me.<\/p>\n

Contexte<\/h2>\n

Les journaux d’acc\u00e8s sont une mine d’or pour les professionnels de l’informatique. Ils permettent de surveiller l’utilisation du syst\u00e8me, de d\u00e9tecter les acc\u00e8s non autoris\u00e9s et d’assurer la responsabilit\u00e9. Le script fourni r\u00e9cup\u00e8re les \u00e9v\u00e9nements de d\u00e9marrage et d’arr\u00eat de la session de l’utilisateur, un ensemble de donn\u00e9es essentiel pour toute strat\u00e9gie de s\u00e9curit\u00e9 informatique solide. En excluant les comptes syst\u00e8me et en se concentrant uniquement sur les utilisateurs authentiques, il pr\u00e9sente un historique clair et concis des acc\u00e8s des utilisateurs, ce qui simplifie la vie des professionnels de l’informatique et des fournisseurs de services g\u00e9r\u00e9s (MSP) et les rend plus efficaces.<\/p>\n
