Building An Automated Sentinel Incident Reporting System With Azure Logic Apps

Security teams often struggle with manual incident reporting, which can be time-consuming and error-prone. This article explores how to automate Microsoft Sentinel incident reporting using Azure Logic Apps, streamlining the entire process from detection to stakeholder notification.

Key Features of the Solution

✅ Automatic Incident Capture: Triggers when new incidents are detected in Sentinel.
✅ Consistent Report Formatting: Ensures all critical details are included in a standardized format.
✅ Timely Notifications: Delivers updates to teams and leadership via email, Teams, or other channels.

You Should Know: Implementing Sentinel Automation with Azure Logic Apps

1. Prerequisites

An active Microsoft Sentinel instance.
Azure Logic Apps configured with necessary permissions.
Office 365 or Teams integration for notifications.

2. Setting Up the Logic App Workflow

Create a new Logic App in the Azure Portal.

2. Set up a trigger for Sentinel incidents:

Use the “When a response to an Azure Sentinel alert is triggered” action.
Configure filters to capture specific incidents.

{
"trigger": {
"type": "Microsoft.SecurityInsights/incidents",
"conditions": [
{
"field": "properties/severity",
"operator": "equals",
"value": "High"
}
]
}
}

Format the Incident Data using a Parse JSON action:

{
"IncidentID": "@{triggerBody()?['IncidentNumber']}",
"Severity": "@{triggerBody()?['Severity']}",
"Description": "@{triggerBody()?['Description']}",
"Timestamp": "@{triggerBody()?['CreatedTimeUTC']}"
}

Send Notifications via Email (Office 365 Outlook connector) or Teams:

Send-MailMessage -To "[email protected]" -Subject "New Sentinel Incident: {IncidentID}" -Body "Severity: {Severity}\nDescription: {Description}" -SmtpServer "smtp.office365.com" -Port 587 -UseSsl -Credential (Get-Credential)

3. Automating Response Actions

Auto-triage incidents using Logic Apps conditions.
Enrich incidents with Threat Intelligence data via API calls.
Log resolved incidents in an Azure SQL database.

INSERT INTO IncidentLog (IncidentID, Severity, Status, ResolvedTime) 
VALUES ('{IncidentID}', '{Severity}', 'Closed', GETDATE());

What Undercode Say

Automating Sentinel incident reporting reduces response time and human error. Key takeaways:
– Use Azure Logic Apps for seamless workflow automation.
– Leverage Microsoft Graph API for advanced integrations.
– Monitor logs with PowerShell or Azure CLI for troubleshooting:

az monitor activity-log list --resource-group "MyResourceGroup" --status "Succeeded" --query "[].{Operation:operationName.localizedValue, Time:eventTimestamp}"

For Linux-based SOC environments, consider these commands:

 Check Azure service status
curl -s -H "Metadata:true" "http://169.254.169.254/metadata/instance?api-version=2021-02-01" | jq .

Monitor Sentinel logs (if using Linux agents)
journalctl -u azsec-monitor --since "1 hour ago" | grep "Incident"

Expected Output: A fully automated Sentinel reporting system that enhances security operations efficiency.
