Integrating Azure services with IBM QRadar involves setting up the necessary connections and configurations to collect and analyze security data from your Azure environment within the QRadar SIEM platform. Here are the detailed steps for integrating Azure services with IBM QRadar:
Before you begin, ensure you have the following prerequisites in place:
- IBM QRadar: Make sure you have a functioning instance of IBM QRadar.
- Azure Account: You need an Azure account with the necessary permissions to configure Azure resources and collect data.
- Azure Resources: The Azure services you want to monitor, such as Azure Security Center, Azure Active Directory, and Azure Monitor, should be configured and running.
- Network Connectivity: Ensure network connectivity between your IBM QRadar instance and your Azure resources.
1. Create an Azure Event Hub:
- Log in to the Azure portal.
- In the Azure portal, navigate to “Create a resource” and search for “Event Hubs.”
- Click “Create” to create a new Event Hub.
- Provide the required information, such as the Event Hub name, namespace, resource group, and region.
- Configure other settings, such as partitions and retention periods, based on your requirements.
- Once the Event Hub is created, make a note of the Event Hub’s connection string.
2. Generate Shared Access Policies for the Event Hub:
- In the Azure portal, navigate to your Event Hub.
- In the Event Hub’s settings, go to the “Shared access policies” section.
- Create one or more shared access policies with the necessary permissions. At a minimum, you’ll need “Send” permissions for QRadar to send data to the Event Hub.
- Note the shared access key for the policy you plan to use with QRadar.
3. Set Up Log Collection in QRadar:
- Log in to your IBM QRadar console.
- Go to the “Admin” tab and select “Log Sources.”
- Click “Add” to add a new log source.
- Choose the appropriate “Log Source Type” based on the Azure service you want to collect logs from (e.g., Azure Security Center, Azure Active Directory, Azure Monitor).
- Configure the log source with the following information:
- Log Source Identifier: A unique name for the log source.
- Protocol Configuration: Select “AzureBlobStorage” for Event Hub.
- Protocol Configuration Parameters: Provide the Azure Event Hub connection string and shared access key.
- Data Collection Status: Set it to “Enabled.”
- Save the log source configuration.
4. Deploy QRadar DSM (Device Support Module):
- QRadar uses DSMs to parse and normalize log data. Ensure that you have the appropriate DSM for the Azure services you want to monitor. You can download the required DSM from the IBM website or the IBM X-Force App Exchange.
- Install and configure the DSM on your QRadar system. Follow the instructions provided with the DSM package.
5. Configure Log Sources for Azure Services:
- In the “Log Sources” section of QRadar, configure the specific log sources for the Azure services you want to monitor (e.g., Azure Security Center, Azure Active Directory, Azure Monitor). Each source may require specific configuration parameters, so refer to QRadar documentation for details.
6. Create a Log Source Group:
- Log source groups help you organize and manage your log sources. To create a log source group:
- In the QRadar console, go to the “Admin” tab.
- Under the “Data Sources” section, select “Log Source Groups.”
- Click “Add” to create a new log source group and assign the relevant log sources to it.
7. Add Log Sources to a QRadar Flow Processor:
- To start collecting Azure logs, you need to assign your log source group to a Flow Processor:
- In the “Admin” tab, go to “Flow Processors.”
- Select a Flow Processor and add your Log Source Group to it.
8. Verify Log Collection:
- Monitor the “Log Activity” tab in QRadar to ensure that logs from Azure services are being collected and processed correctly. You should see log events from your Azure sources in this section.
9. Create Rules and Alerts:
- Use QRadar’s rule and alert creation features to define conditions and actions based on the Azure log data. This can include setting up alerts for specific security events or anomalies detected in Azure services.
10. Test and Monitor:
- Continuously monitor the integration to ensure that log data is being collected, and that alerts are triggered as expected. Regularly review and adjust your rules and alerts as needed.
11. Automate Incident Response:
- QRadar can be configured to automate incident response actions based on specific rules and alerts. Set up workflows and actions to respond to security incidents quickly and efficiently.
12. Regular Maintenance:
- Periodically review and update your integration to account for changes in your Azure environment, QRadar configuration, and the evolving threat landscape. Keep your DSMs and rules up to date to stay effective in threat detection and response.
By following these steps, you can successfully integrate Azure services with IBM QRadar, enabling you to monitor and analyze security data from your Azure environment within the SIEM platform. This integration is crucial for enhancing your organization’s cybersecurity posture and incident response capabilities.
