Windows Event Log Analysis

Windows event logs can provide valuable evidence during security investigations.

Why event logs matter

Event logs record system activity, authentication events, application errors, and other information useful for incident response.

Investigation workflow

1. Identify the relevant log sources.
2. Establish the time range of interest.
3. Correlate events with other available evidence.
4. Document findings and limitations.

Example: PowerShell Event Log Query

The following command retrieves the latest 20 System log events:

Get-WinEvent -LogName System -MaxEvents 20 |
  Select-Object TimeCreated, Id, ProviderName, LevelDisplayName |
  Format-Table -AutoSize

This command is useful for quickly reviewing recent system events during an initial investigation.

Conclusion

Reliable analysis depends on context, accurate timestamps, and correlation between multiple sources.
