How to Configure Azure Sentinel for Advanced Threat Detection

November 28, 20235 min read

Azure Sentinel is Microsoft’s cloud-native Security Information and Event Management (SIEM) and Security Orchestration Automated Response (SOAR) solution. It provides intelligent security analytics and threat intelligence across your enterprise, offering a single solution for alert detection, threat visibility, proactive hunting, and threat response. Below is a detailed guide on configuring Azure Sentinel for advanced threat detection.

Section 1: Preconfiguration Steps

Before diving into Azure Sentinel configuration, ensure you have the following prerequisites:

  • An active Azure subscription.
  • Required permissions to create and manage resources within the Azure portal.
  • A clear understanding of the data sources that you will be integrating with Azure Sentinel.

Section 2: Deployment and Initial Setup

  • Creating an Azure Sentinel Instance
    1. Log in to the Azure Portal.
    2. Search for and select Azure Sentinel.
    3. Choose the “Create Azure Sentinel” option.
    4. Select or create a new Log Analytics workspace which will store the data that Azure Sentinel will analyze.

Section 3: Connect Data Sources

Azure Sentinel’s threat detection capabilities are built on the data it analyzes. Follow these steps to connect data sources:

  • Navigate to Data Connectors
    • In the Azure Sentinel dashboard, click on “Data connectors” from the sidebar menu.
  • Select and Configure Connectors
    • Choose from the list of available connectors for your cloud and on-premises solutions.
    • For each connector, select “Open connector page” to view setup instructions.
    • Follow the instructions to configure the connector, which will likely involve authorizing Azure Sentinel to access the data source.

Section 4: Analytics Configuration

Analytics rules help identify potential security threats. Here’s how to configure them:

  • Create Custom Detection Rules (Optional)
    • In the Azure Sentinel dashboard, navigate to “Analytics”.
    • Click on “+ Add new rule” to create a custom rule or select from existing templates.
    • Tailor the rule logic and parameters to match specific scenarios of interest.
  • Utilize Predefined Templates
    • Azure Sentinel provides a range of templates for common use cases and threats. Enable those that apply to your environment.
  • Define Rule Logic
    • Set appropriate conditions using the Kusto Query Language (KQL).
    • Define the severity, frequency, and other parameters for rule evaluation.

Section 5: Visualization with Workbooks

Visualizing data is critical in threat detection and response efforts:

  • Accessing Workbooks
    • From the Azure Sentinel sidebar menu, click on “Workbooks”.
  • Select Templates or Create New
    • Choose a template workbook that suits your needs or create a new one from scratch to customize your dashboards.
  • Configure and Publish Workbooks
    • By using the edit feature, you can configure the visuals and data representations.
    • Once configured, save and publish the workbook for regular use.

Section 6: Implement Threat Hunting

Proactively search for potential threats with threat hunting queries:

  • Leverage Hunting Queries
    • Within Azure Sentinel, go to the “Hunting” section. Here you will find pre-built queries to help start your hunt.
  • Execute and Analyze Results
    • Run queries to search through historical data for suspicious patterns or activities.
    • You can modify these queries or write new ones as needed.

Section 7: Incident Response

When a threat is detected, it’s time for incident response:

  • Review Incidents
    • In the “Incidents” pane, you’ll find alerts that have been classified as incidents.
    • Investigate each incident to understand its nature and potential impact.
  • Automating Responses with Playbooks
    • To handle incidents efficiently, set up playbooks in Azure Logic Apps, which can automate your response processes.
    • Trigger these playbooks based on specific incident criteria.

Section 8: Review and Maintenance

Continuously assess Azure Sentinel’s performance:

  • Performance Monitoring
    • Regularly check and tune the analytics rules.
    • Keep an audit log of responses and review the accuracy of incident detection.
  • Updates and Scaling
    • Stay updated with the latest features and improvements in Azure Sentinel.
    • Scale your resources based on the data volume and organizational needs.


Configuring Azure Sentinel for advanced threat detection is an ongoing process that involves setting up the environment, connecting to data sources, creating analytics rules, visualizing data through workbooks, conducting proactive threat hunting, responding to incidents, and maintaining the setup. By following these detailed steps, you can leverage Azure Sentinel’s full capabilities to fortify your organization’s security posture.
