Integrate with Microsoft Sentinel (Optional)

Integrating Microsoft Sentinel into your security framework can help enhance threat detection and response capabilities. Below is a step-by-step guide to integrate Microsoft Sentinel:

---

Step 1: Prerequisites

Before starting, ensure the following:

• A Microsoft Azure account with sufficient permissions (e.g., Owner or Contributor role on the subscription level).
• An active Log Analytics Workspace to store and analyze data.
• Microsoft Sentinel is enabled in your subscription.

---

Step 2: Enable Microsoft Sentinel

1. Access the Azure Portal: Log in to Azure Portal.
2. Navigate to Sentinel:
   • In the search bar, type “Microsoft Sentinel” and select it.
3. Add Microsoft Sentinel to a Workspace:
   • Click + Create or + Add.
   • Choose an existing Log Analytics Workspace or create a new one:
     • If creating a new one, specify the name, region, and pricing tier.
     • Select Review + Create and then click Create.

Step 3: Connect Data Sources

1. Access Sentinel’s Data Connectors:
   • Go to your Sentinel instance.
   • In the left-hand menu, select Data connectors.
2. Choose Data Sources:
   • Select the connectors for the data you want Sentinel to monitor (e.g., Azure Active Directory, Microsoft Defender for Endpoint, Office 365).
   • Follow the configuration instructions provided for each connector.
   • Enable the Log Analytics agent for non-Azure data sources, if applicable.
3. Validate Connection:
   • Ensure that data ingestion is active by checking the Logs section in the workspace.

Step 4: Set Up Analytics Rules

1. Navigate to Analytics:
   • In Sentinel, go to Analytics.
2. Create Analytics Rules:
   • Select + Create and choose a rule template or create a custom rule.
   • Specify:
     • Rule name and description.
     • Data source and query logic (KQL).
     • Alert trigger conditions.
     • Action group for notifications (optional).
3. Enable the Rule:
   • Click Save or Enable to activate the rule.

Step 5: Set Up Incident Management

1. Navigate to Incidents:
   • In Sentinel, click Incidents.
2. Monitor and Manage Incidents:
   • Review detected incidents.
   • Assign incidents to team members, change statuses, or investigate further using Entity Behavior Analytics and logs.
3. Automate Responses (Optional):
   • Use Playbooks (based on Azure Logic Apps) to automate responses for incidents.

---

Step 6: Set Up Workbooks for Visualization

1. Access Workbooks:
   • Go to Workbooks in Sentinel.
2. Choose or Create Workbooks:
   • Select pre-built workbooks for data visualization.
   • Customize or create your own workbook for specific monitoring needs.
3. Save and Share:
   • Save the workbook to the workspace and share it with team members.

---

Step 7: Integrate with Third-Party Tools (Optional)

• Use Sentinel’s REST API or Logic Apps to integrate with third-party tools like Jira, Slack, or ticketing systems.
• Install connectors for non-Azure platforms (e.g., AWS, on-premise firewalls) for extended coverage.

---

Step 8: Monitor and Optimize

1. Check Sentinel Metrics:
   • Go to the Logs section and monitor log ingestion and query performance.
2. Refine Rules:
   • Regularly update or modify analytics rules to adapt to new threats.
3. Review Costs:
   • Keep track of data ingestion and retention costs in the Cost Management section.

---

Optional: Advanced Integration with SOC

• SOAR (Security Orchestration, Automation, and Response):
  • Design complex automated workflows using Playbooks.
• Integrate with Azure Sentinel GitHub Community:
  • Access community-provided playbooks, workbooks, and custom detection rules.
