Microsoft Sentinel continues to evolve, bringing cutting-edge features to enhance Security Operations Centers (SOCs). Here are the latest advancements:
✅ Case Management to GA with Expanded Functionality
✅ New Recommendation Types for SOC Optimization (Coming in April)
✅ Security Copilot Enriched Incident Summaries (Public Preview in April)
✅ Multi-Tenant and Multi-Workspace Capabilities (GA in May)
✅ Advancing Threat Intelligence
✅ New and Improved Data Connectors

You Should Know:
To leverage these new Sentinel features effectively, here are some essential commands and steps for security professionals:
1. Case Management Automation
Use PowerShell to automate case creation and management in Sentinel:
<h1>Connect to Azure</h1> Connect-AzAccount <h1>Get Sentinel Incident</h1> Get-AzSentinelIncident -ResourceGroupName "YourRG" -WorkspaceName "YourWorkspace" <h1>Create a new case</h1> New-AzSentinelIncident -ResourceGroupName "YourRG" -WorkspaceName "YourWorkspace" -Id "NewCase01" - "Phishing Attempt" -Severity "High"
2. Multi-Tenant SOC Management
For managing multiple tenants, use Azure Lighthouse:
<h1>Register Azure Lighthouse</h1> az provider register --namespace "Microsoft.ManagedServices" <h1>Assign roles across tenants</h1> az role assignment create --assignee "[email protected]" --role "Security Reader" --scope "/tenants/TenantID"
3. Threat Intelligence Integration
Enhance threat detection with STIX/TAXII feeds:
<h1>Install Python library for TAXII</h1>
pip install stix2
<h1>Fetch threat intel via TAXII</h1>
from stix2 import TAXIICollectionSource
taxii_src = TAXIICollectionSource("https://threatintel.example.com/api/")
indicators = taxii_src.query([Filter("type", "=", "indicator")])
4. Security Copilot & Incident Summaries
Automate incident summaries using Azure Logic Apps:
{
"actions": {
"GetIncidentSummary": {
"type": "Sentinel",
"inputs": {
"incidentId": "@triggerBody()?['IncidentID']",
"summaryType": "SecurityCopilot"
}
}
}
}
5. Sentinel Data Connectors
Deploy a Syslog connector for Linux logs:
<h1>Configure Syslog on Linux</h1> sudo vi /etc/rsyslog.conf <h1>Add Sentinel workspace ID</h1> <em>.</em> @(o)your-sentinel-workspace.ods.opinsights.azure.com;SecurityGatewayFormat
What Undercode Say:
Microsoft Sentinel’s new features significantly enhance SOC efficiency, from automated case management to AI-driven insights. Security teams should:
– Automate repetitive tasks using PowerShell and Logic Apps.
– Leverage multi-tenant visibility via Azure Lighthouse.
– Integrate threat intelligence (STIX/TAXII) for proactive defense.
– Monitor logs efficiently with Syslog and custom connectors.
For optimal SOC performance, combine Sentinel with KQL queries for advanced hunting:
[kusto]
SecurityEvent
| where EventID == 4625
| summarize FailedLogins = count() by Account
| where FailedLogins > 5
[/kusto]
Expected Output:
- Automated incident reports from Security Copilot.
- Centralized SOC operations across multiple tenants.
- Enhanced threat detection with real-time intel feeds.
- Streamlined log ingestion via new data connectors.
