Secure User Account Audit Script

Security & AuditingJanuary 13, 2025

In this post, we will share a useful PowerShell script that audits user accounts for security compliance. This script will help system administrators identify inactive user accounts and report them for further action. This is an important step in maintaining a secure environment by ensuring that only active accounts have access to critical resources.

powershell
$logFile = "C:\UserAccountAudit.log"
$inactiveDaysThreshold = 90

$currentDate = Get-Date

$users = Get-ADUser -Filter * -Property LastLogonDate

$inactiveUsers = $users | Where-Object {
    ($currentDate - $_.LastLogonDate).Days -gt $inactiveDaysThreshold
}

if ($inactiveUsers) {
    $inactiveUsers | ForEach-Object {
        Add-Content -Path $logFile -Value "$($_.Name) is inactive since $($_.LastLogonDate)"
    }
} else {
    Add-Content -Path $logFile -Value "No inactive accounts found."
}

Get-Content -Path $logFile | Write-Host
