You Should Know: Key Deployment Steps & Commands
1. Prerequisites for Defender XDR Deployment
- Ensure Azure AD is configured.
- Verify Microsoft 365 Defender licensing.
- Required permissions: Global Admin or Security Admin.
2. Enable Microsoft Defender XDR
Run in PowerShell (Admin):
Connect to Microsoft 365 Security Connect-ExchangeOnline -UserPrincipalName [email protected] Enable-OrganizationCustomization
3. Configure Defender for Endpoint
Install Defender for Endpoint onboarding package .\WindowsDefenderATPOnboardingPackage.exe
4. Integrate Defender for Office 365
Enable Safe Attachments & Links Set-AtpPolicyForO365 -EnableATPForSPOTeamsODB $true
5. Deploy Defender for Identity
Linux sensor installation (if applicable) sudo apt-get install mdatp
6. Verify Defender XDR Functionality
Check Defender XDR status Get-M365DSecurityStatus
7. Enable Advanced Hunting
Use KQL (Kusto Query Language) for threat detection:
DeviceEvents | where ActionType == "AntivirusScanCompleted" | summarize count() by DeviceName
What Undercode Say
Deploying Microsoft Defender XDR requires careful planning, but the new setup guides simplify the process. Key takeaways:
– Use PowerShell for automation.
– Verify integrations (Endpoint, Office 365, Identity).
– Leverage Advanced Hunting for proactive threat detection.
For Linux systems, ensure MDATP is installed:
sudo apt update && sudo apt install mdatp
For Windows hardening, apply:
Set-MpPreference -AttackSurfaceReductionRules_Ids <RuleID> -AttackSurfaceReductionRules_Actions Enabled
