$trigger = New-ScheduledTaskTrigger -Daily -At 12am
Register-ScheduledTask -Action $action -Trigger $trigger -TaskName "SecurityLogExport" -Description "Daily Security Log Export"
Important Notes: - Requires administrative privileges - Consider log size and retention policies - Be aware of system performance impact when running large queries - Always test filters before running on production systems - Consider storage space requirements for exports - Use appropriate file permissions for exported logs These methods provide various ways to access and export security events using only built-in Windows tools, allowing for both manual and automated log collection and analysis.

- Open Event Viewer (eventvwr.msc)
- Navigate to Windows Logs -> Security
- Right-click "Security" and select "Save All Events As..."
- Choose a location and save as .evtx format
2. Using Windows Management Instrumentation Command-line (WMIC):
1
wmic ntevent where "logfile='Security'" list full > security_events.txt
3. Using PowerShell commands: Basic event export:
1
Get-WinEvent -LogName Security | Export-Csv -Path "C:\security_events.csv"
Filtered export (last 24 hours):
1
2
3
4
5
$StartTime = (Get-Date).AddDays(-1)
Get-WinEvent -FilterHashTable @{
    LogName='Security';
    StartTime=$StartTime
} | Export-Csv -Path "C:\last24h_security_events.csv"
Export specific event IDs (e.g., 4624 for successful logons):
1
2
3
4
Get-WinEvent -FilterHashTable @{
    LogName='Security';
    ID=4624
} | Export-Csv -Path "C:\logon_events.csv"
4. Using built-in wevtutil command: Export entire security log:
1
wevtutil epl Security C:\security_log.evtx
Export and convert to XML:
1
wevtutil qe Security /f:xml > security_events.xml

    ID=4624,4625,4634
} | Select-Object TimeCreated, ID, Message | 
Export-Csv -Path "C:\filtered_security_events.csv" -NoTypeInformation
Key points for implementation: 1. Access Rights: - Must run as Administrator - Need appropriate security permissions to access logs 2. Performance Considerations: - Large log files can take time to process - Consider using filters to limit data size - Export during low-activity periods 3. Storage Requirements: - Ensure sufficient disk space for exports - .evtx files maintain all metadata - CSV/TXT exports are smaller but contain less detail 4. Filtering Best Practices: - Use specific time ranges - Filter by relevant Event IDs - Include only needed fields 5. Common Event IDs to monitor:

Important Considerations: 1. Permissions: - Must run as Administrator for most operations - Requires appropriate security permissions to access logs 2. Performance: - Large exports can be resource-intensive - Consider using filters to limit data size - Use date ranges when possible 3. Storage: - Monitor available disk space for exports - .evtx files maintain full metadata - .csv/.txt files are more portable but lose some metadata 4. Best Practices: - Always maintain original logs - Use specific filters to reduce noise - Document export criteria - Include timestamps in filenames - Consider compression for large exports Remember to adjust paths and filters based on your specific needs and environment. These commands provide a foundation that you can modify for your specific use case.
