Step two. With WMI, you can also query the same exact BIOS information remotely, by using the WMIObject Cmdlet’s -computername parameter, as demonstrated below: Get-WMIObject Win32_BIOS –computername PCNAME The resulting output from running the command should appear like the image below: Step three. A Few Last Words: Using PowerShell and WMI Events Queries for Powerful Notifications.

I had to re-write last two parts of the series. So, lot of links you might have bookmarked may not be valid since the entire blog content went through a churn. So, I thought it will be good to publish one post with links to all articles in this series. So, here it is — all 10 parts of the series. 1. So, what is next?

By Jeff Hicks - November 15, 2011 Introduction IT Pros responsible for Windows Servers are hopefully already familiar with Windows Management Instrumentation, or WMI.
This technology has been a staple in Microsoft operating systems since the days of Windows 2000. Using WMI we can identify all types of management and system information from the BIOS to logical disks to the operating system. In the past, if we wanted to access this treasure trove of information we typically used VBScript. The primary cmdlet is Get-WMIObject. WMI datetime First up is converting those ugly WMI datetime strings like this: 20110128161223.000000-300. PS S:\> get-wmiobject win32_operatingsystem | select InstallDate,Caption InstallDate Caption ----------- ------- 20110128161223.000000-300 Microsoft Windows 7 Ultimate It would be much nicer if the install date was more user-friendly.

PowerShell Tutorial 11 – Part 3: Scripting with Windows Management Instrumentation (WMI) – Creating Reports In this, the last installment of the WMI tutorials we tackle creating reports.
Up until this point we have only been concern with outputting our results to the console. Being that we are in the real world and we work for bosses that like little “picture thingys” and reports, we need to send results to files. There is one small problem… the WMI Scripts on this site (so far) and the scripts in the Microsoft Script Repository only output results to the screen (Write-Host). When using “Write-Host, output is sent to the console and that’s it, the data no longer exists, there is nothing to redirect (>) or pipe (|) to another cmdlet or file. We will use an edited version of the List BIOS Information script found in the Microsoft Scripting Repository. $strComputer = “.” $colItems = get-wmiobject -class “Win32_BIOS” -namespace “rootCIMV2″ ` -computername $strComputer -or- Changes: 1. .BIOS.ps1.
Auditar grupos críticos y alertar por mail en Active Directory. Es muy importante para todo administrador de seguridad conocer en todo momento quienes tienen cuentas de usuario con privilegios elevados y "vigilarlos". A partir de esto se desprende que es todavía más importante saber cuando se otorgan privilegios a usuarios. En todo dominio existen grupos de usuario utilizados por administradores o helpdesk que cuentan con mayores privilegios que los usuarios comunes, por obvias razones. El problema es cuando se asignan estos privilegios y no todos (o ninguno) los administradores están informados. El caso más riesgoso es cuando un atacante logra escalar privilegios gracias a algún exploit o vulnerabilidad conocida (se acuerdan de pass-the-hash?). Active Directory posee grupos bien definidos con privilegios elevados, siendo "Domain Admins" el Dios supremo. Cada organización puede definir sus propios grupos, pero "Domain Admins" estará siempre presente como la autoridad máxima, así que debe estar auditado.
