Active Directory Audit Scripts
The scripts on this page are designed to query Active Directory to extract data for audit-related purposes. These scripts were designed by the Arizona Auditor General's IT Audit team for internal purposes, but have been released to assist similar government audit shops in Active Directory work.
The scripts on this page were compiled by from the work and research of others. We wish to thank the communities around Active Directory, Windows, Python, and PowerShell for making content readily and freely accessible for the benefit of others.
Querying an Active Directory Domain
-
Download the script (right-click "script" and choose 'Save As') from the repository. Alternatively, download a zip file to of the entire repository.
-
Open PowerShell either directly on server or on a management workstation with RSAT installed.
-
If running directly on server, you should run from an Administrative PowerShell Prompt (Avoids UAC issues).
-
Use the following command to bring your PowerShell working directory to the location where you placed the script (edit location as appropriate).
PS C:\> cd C:\Users\EmployeeName\Desktop -
-
Run the script: .\Get-ADAuditData.ps1
Example:
PS C:\Users\EmployeeName\Desktop> .\Get-ADAuditData.ps1
-
'Get-Help .\Get-ADAuditData' to read the built-in help, if you need to use the built-in parameters.
Example:
PS C:\Users\EmployeeName\Desktop> Get-Help .\Get-ADAuditData
Analyzing the data
Through the use of these scripts, the Arizona Auditor General has gravitated towards using SQL Server for analysis. The primary reasons for this were instabilities with Excel in large AD environments and desire for standardized queries. The files can be imported quickly, run against a standard, but flexible set of queries, and can be compared to other relevant data sets.
A .sql file containing sample queries has been uploaded to this repository to show standard checks run by the Arizona Auditor General. These checks are not an exhaustive list of everything that can be reviewed in an Active Directory domain, nor are they necessarily the items that you will want to review for your environment/audit. These are simply the checks that have, over the years, shown to be areas of frequent issues.
If you do not use SQL Server, you can still use the .sql file for inspiration for your own checks, using your own audit tool(s) of choice.
