La detecci\u00f3n del tiempo de inactividad en los ordenadores es un aspecto cr\u00edtico para los profesionales de TI, especialmente en la era del aumento de las amenazas a la ciberseguridad y la gesti\u00f3n de recursos. A medida que las organizaciones se digitalizan r\u00e1pidamente y los usuarios suelen permanecer conectados durante largos periodos, detectar el tiempo de inactividad del usuario<\/strong> se convierte en algo primordial tanto por motivos de seguridad como operativos. En este post, profundizaremos en un script de PowerShell dise\u00f1ado para detectar el tiempo de inactividad del usuario, haciendo que la tarea sea fluida y eficiente.<\/p>\n

Antecedentes<\/h2>\n

La capacidad de determinar cu\u00e1nto tiempo ha estado inactivo un usuario puede proporcionar informaci\u00f3n valiosa para los profesionales de TI y los proveedores de servicios gestionados (MSP). Tanto si se trata de liberar recursos como de garantizar que las sesiones no permanezcan abiertas a posibles amenazas para la seguridad, o incluso de consideraciones de facturaci\u00f3n para los proveedores de servicios en la nube, disponer de un m\u00e9todo eficaz y fiable para determinar la inactividad de los usuarios se convierte en algo esencial. Este script en particular le saca el m\u00e1ximo partido a PowerShell para interactuar directamente con el sistema operativo Windows y extraer datos relevantes para medir los tiempos de inactividad.<\/p>\n

#Requires -Version 5.1\r\n\r\n<#\r\n.SYNOPSIS\r\n    Returns the longest idle time of any user logged in or for a specific user.\r\n.DESCRIPTION\r\n    Returns the longest idle time of any user logged in or for a specific user.\r\n    If RDS(Remote Desktop Services) is installed and the RSAT tools for it as well,\r\n     then this will get the idle time of each logged in user.\r\n    For workstations and servers(with out RDS installed),\r\n     this will get the current idle of the currently logged in user.\r\n    If a user is logged in via the console and another is via the admin RDP session,\r\n     then both will be considered as one user for calculating idle time.\r\n.EXAMPLE\r\n    No parameters needed.\r\n    Returns the longest idle time of all users logged in.\r\n.EXAMPLE\r\n     -UserName \"Fred\"\r\n    Returns the longest idle time of the user Fred.\r\n.EXAMPLE\r\n    PS C:> Get-User-Idle-Time.ps1 -UserName \"Fred\"\r\n    Returns the longest idle time of the user Fred.\r\n.OUTPUTS\r\n    PSCustomObject[]\r\n.NOTES\r\n    Minimum OS Architecture Supported: Windows 10, Windows Server 2016\r\n    Release Notes:\r\n    Adds functions to get idle time from RDS and non-RDS computers.\r\nBy using this script, you indicate your acceptance of the following legal terms as well as our Terms of Use at https:\/\/www.ninjaone.com\/terms-of-use.\r\n    Ownership Rights: NinjaOne owns and will continue to own all right, title, and interest in and to the script (including the copyright).
