How to easily integrate Azure logs with Microsoft Sentinel | Step-by-step guide for beginners

1. Overview

When operating an Azure environment, log management is an essential component of optimizing security and performance. However, it is not easy to efficiently manage and analyze huge amounts of log data. That's where Microsoft Sentinel comes in.

Microsoft Sentinel is a cloud-based security information and event management (SIEM) solution that supports Azure. In this article, we'll provide an easy-to-understand explanation of how to integrate Azure logs with Microsoft Sentinel.

2. Steps to integrate Azure Logs with Microsoft Sentinel

2.1 Preparatory Steps

First, check the following to integrate Azure logs with Sentinel:

1. Check the Azure Log Type

• Entra ID logs
  • Activity log

*This time, we will cover the above two

2. Confirm and grant necessary permissions

• To set up Microsoft Sentinel, you must have the Contributor or Log Analytics Contributor permission in your Azure subscription.

2.2 Step 1: Create a Microsoft Sentinel Workspace

1. Go to the Azure portal and search for "Microsoft Sentinel".
2. Select "Add Workspace".
3. Select the appropriate Log Analytics workspace or create a new one.

2.3 Step 2: Connect Azure Resources

1. Open the "Content Hub" in your Sentinel workspace.
2. Search for the Azure resources you want to use (e.g., Entra ID, Azure Activity) and install them.
3. Verify that the above resource exists from Configuration - Data Connector.

2.4 Step 3: Apply the Analysis Template

1. Open Analytics in your Sentinel workspace.
2. Create rules for the resources you have linked this time.

The specified rules now cause incidents.

3. Tips for mastering Microsoft Sentinel

• Common Problems and Their Solutions

• If you don't see logs: Double-check your connection settings and permissions.

  • Excessive incidents: Adjust the rules appropriately.

• Utilization of KQL (Kusto Query Language)

• Make full use of log queries to efficiently extract the data you need.

  • Example: A query to retrieve activity logs for a specific IP address.

• Key points of regular operational monitoring

• Leverage Sentinel's dashboards to identify anomalies on a daily basis.

4. Conclusion

In order to make better use of Microsoft Sentinel, it is important to work with other logs to set rules appropriately. In addition, security can be strengthened by monitoring, analyzing, and investigating incidents that occur on a daily basis.
