Practice Verified Codes and Commands:
1. Check Entra ID Sync Status (PowerShell):
Get-ADSyncScheduler
This command helps you verify the synchronization status between Entra ID and Active Directory.
2. List Hybrid Joined Devices:
Get-MsolDevice -All | Where-Object {$_.DeviceTrustType -eq "Hybrid Azure AD Joined"}
Use this to identify devices that are hybrid joined in your environment.
3. Audit Entra ID Sign-Ins:
Get-AzureADAuditSignInLogs -Top 100
This retrieves the last 100 sign-in logs for auditing purposes.
4. Check Active Directory Replication Status:
repadmin /showrepl
Ensures that Active Directory replication is functioning correctly in a hybrid setup.
5. Enable Entra ID Diagnostic Settings (Azure CLI):
az monitor diagnostic-settings create --resource <ResourceID> --name <DiagnosticName> --logs '[{"category": "AuditLogs", "enabled": true}]'
This command enables diagnostic logging for Entra ID in Azure.
6. Verify Conditional Access Policies:
Get-AzureADMSConditionalAccessPolicy
Lists all Conditional Access policies applied to your Entra ID environment.
7. Test Hybrid Connectivity (Ping):
ping <OnPremisesDomainController>
Ensures network connectivity between Azure and on-premises infrastructure.
8. Check Entra ID Role Assignments:
Get-AzureADDirectoryRole | ForEach-Object { Get-AzureADDirectoryRoleMember -ObjectId $_.ObjectId }
Lists all role assignments in Entra ID for security auditing.
9. Export Entra ID Sign-In Logs (Azure CLI):
az monitor log-analytics query --workspace <WorkspaceID> --query "AzureActivity | where CategoryValue == 'SignInLogs'" --output table
Exports sign-in logs for further analysis.
10. Monitor Entra ID Risky Sign-Ins:
Get-AzureADRiskyUser -All $true
Identifies users with risky sign-ins for further investigation.
What Undercode Say:
Hybrid environments, combining Entra ID and Active Directory, are increasingly complex and critical to secure. Understanding the interplay between these systems is essential for modern cybersecurity professionals. The commands and scripts provided above offer practical ways to monitor, audit, and secure hybrid setups.
For instance, using PowerShell to check synchronization status or Azure CLI to enable diagnostic logging ensures you have visibility into your environment. Regularly auditing role assignments and risky sign-ins helps mitigate potential threats. Additionally, tools like `repadmin` and `ping` ensure that your on-premises and cloud infrastructure are seamlessly connected.
As hybrid environments evolve, so do the attack vectors. Staying ahead requires not only theoretical knowledge but also hands-on practice with tools and commands. The series mentioned in the article is a valuable resource for deepening your understanding of Entra ID and Active Directory security.
For further reading, explore Microsoft’s official documentation on Entra ID and Active Directory.
By mastering these commands and concepts, you can better defend your hybrid environments against emerging threats. Stay vigilant, keep learning, and always validate your configurations with practical testing.
