Streamline IT operations with ready-to-use scripts for centralized logging, email alerts, SIEM integration, and advanced monitoring. Unlock efficiency and enhance security with detailed automation solutions.
You Should Know:
1. Bulk User Creation in Active Directory
<h1>Import Active Directory module</h1>
Import-Module ActiveDirectory
<h1>CSV format: Name,SamAccountName,GivenName,Surname,UserPrincipalName,Password</h1>
$users = Import-Csv -Path "C:\Users.csv"
foreach ($user in $users) {
New-ADUser -Name $user.Name `
-SamAccountName $user.SamAccountName `
-GivenName $user.GivenName `
-Surname $user.Surname `
-UserPrincipalName $user.UserPrincipalName `
-AccountPassword (ConvertTo-SecureString $user.Password -AsPlainText -Force) `
-Enabled $true
}
2. Cleanup Inactive Accounts (30+ Days)
$inactiveThreshold = (Get-Date).AddDays(-30) $inactiveUsers = Search-ADAccount -AccountInactive -DateTime $inactiveThreshold -UsersOnly $inactiveUsers | Disable-ADAccount $inactiveUsers | Export-Csv -Path "C:\InactiveUsers.csv" -NoTypeInformation
3. Email Notifications for Critical Events
$smtpServer = "smtp.yourdomain.com" $to = "[email protected]" $from = "[email protected]" $subject = "Critical Event Alert" $body = "Check Event Log for critical issues." Send-MailMessage -SmtpServer $smtpServer -To $to -From $from -Subject $subject -Body $body
4. SIEM Integration (Splunk, ELK, Azure Sentinel)
<h1>Forward logs to Splunk HTTP Event Collector</h1>
$logData = @{
event = Get-EventLog -LogName System -EntryType Error -Newest 10
}
Invoke-RestMethod -Uri "https://your-splunk-server:8088/services/collector" `
-Method Post `
-Headers @{Authorization = "Splunk YOUR_TOKEN"} `
-Body (ConvertTo-Json $logData)
5. Real-Time Monitoring & Dashboards
<h1>Monitor CPU/Memory Usage</h1> Get-Counter '\Processor(_Total)\% Processor Time', '\Memory\Available MBytes' | Export-Csv -Path "C:\PerfStats.csv" -Append <h1>Generate HTML Dashboard</h1> ConvertTo-Html -InputObject (Get-Process | Sort-Object CPU -Descending | Select -First 10) | Out-File "C:\ProcessReport.html"
What Undercode Say:
PowerShell automation is a game-changer for IT administrators managing Active Directory and Windows Server environments. By leveraging scripts for bulk operations, log centralization, and SIEM integration, teams can drastically reduce manual effort while improving security.
Key Takeaways:
- Automate repetitive tasks (user provisioning, cleanup).
- Enhance monitoring with real-time alerts.
- Integrate with SIEM tools for better threat detection.
Expected Output:
Users created successfully. Inactive accounts disabled and exported. Email alert sent. Logs forwarded to Splunk. Performance stats logged.
