L’un des aspects essentiels du maintien de la s\u00e9curit\u00e9 du syst\u00e8me est le suivi des administrateurs locaux sur les machines Windows. L’utilisation de PowerShell pour r\u00e9cup\u00e9rer ces donn\u00e9es peut \u00eatre tr\u00e8s utile \u00e0 de nombreux professionnels de l’informatique.

PowerShell est devenu un langage de script et un shell performant. Pour les professionnels de l’informatique et les fournisseurs de services g\u00e9r\u00e9s (MSP)<\/a> en particulier, des scripts comme celui qui est propos\u00e9 sont devenus indispensables. Les MSP g\u00e8rent souvent plusieurs environnements clients, ce qui rend difficile le contr\u00f4le manuel de chaque d\u00e9tail. En utilisant des scripts pour r\u00e9cup\u00e9rer des informations, telles que la liste des administrateurs locaux, les MSP peuvent s’assurer que seules les personnes autoris\u00e9es disposent d’un acc\u00e8s \u00e9lev\u00e9, ce qui les prot\u00e8ge contre les menaces potentielles et les activit\u00e9s malveillantes.<\/p>\n
