![]() You can use the Apply to drop-down to set filters to send only specific alerts and activities to your SIEM server. Use the slider to enable and disable them, by default, everything is selected. Select which data types you want to export to your SIEM server for Alerts and Activities. You can work with your security admin to get these details if you don't have them. Select TCP or UDP as the Remote Syslog protocol. Type in the IP address or hostname of the Remote syslog host and the Syslog port number. In the wizard, fill in a name, and Select your SIEM format and set any Advanced settings that are relevant to that format. On the SIEM agents tab, select "add" ( +), and then choose Generic SIEM. In the Defender for Cloud Apps portal, under the Settings cog, select Security extensions. ![]() Integrating with your SIEM Step 1: Set it up in the Defender for Cloud Apps portal Set your firewall as described in Network requirements.A standard Windows or Linux server (can be a virtual machine). ![]() Validate that the SIEM agent is working.Download the JAR file and run it on your server.Set it up in the Defender for Cloud Apps portal.Integrating with your SIEM is accomplished in three steps: Defender for Cloud Apps uses the network configurations you provided during the setup (TCP or UDP with a custom port).ĭefender for Cloud Apps currently supports Micro Focus ArcSight and generic CEF. Once the SIEM agent retrieves the data from Defender for Cloud Apps, it sends the Syslog messages to your local SIEM. The traffic is then sent over an encrypted HTTPS channel on port 443. When deployed and configured, it pulls the data types that were configured (alerts and activities) using Defender for Cloud Apps RESTful APIs. The SIEM agent is deployed in your organization's network. For example, decide where you intend to perform alert management, and then stop SIEM notifications being sent from the other service. To avoid duplication and confusion, make sure to handle the scenario. One alert will be issued from each service and they will have different alert IDs. If you are integrating Microsoft Defender for Identity in Defender for Cloud Apps and both services are configured to send alert notifications to a SIEM, you'll start to receive duplicate SIEM notifications for the same alert.

Microsoft security graph API - An intermediary service (or broker) that provides a single programmatic interface to connect multiple security providers.For information about integrating with Microsoft Sentinel, see Microsoft Sentinel integration. Microsoft Sentinel - A scalable, cloud-native SIEM and SOAR for native integration.If you disable this feature for an extended period, then re-enable, the past two days of alerts and activities are forwarded and then all alerts and activities from then on.Īdditional integration solutions include: When you first integrate your SIEM with Defender for Cloud Apps, activities and alerts from the last two days will be forwarded to the SIEM and all activities and alerts (based on the filter you select) from then on. The Microsoft Defender for Cloud Apps SIEM agent runs on your server and pulls alerts and activities from Microsoft Defender for Cloud Apps and streams them into the SIEM server. Integrating with a SIEM service allows you to better protect your cloud applications while maintaining your usual security workflow, automating security procedures, and correlating between cloud-based and on-premises events. As new activities and events are supported by connected apps, visibility into them is then rolled out into Microsoft Defender for Cloud Apps. You can integrate Microsoft Defender for Cloud Apps with your generic SIEM server to enable centralized monitoring of alerts and activities from connected apps. For more information about these changes, see Microsoft Defender for Cloud Apps in Microsoft 365 Defender. Microsoft 365 Defender will be the home for monitoring and managing security across your Microsoft identities, data, devices, apps, and infrastructure. This will simplify workflows, and add the functionality of the other Microsoft 365 Defender services. The Microsoft 365 Defender portal allows security admins to perform their security tasks in one location. Microsoft Defender for Cloud Apps (previously known as Microsoft Cloud App Security) is now part of Microsoft 365 Defender.
