## Detect plug and play connected events ### Respond to threats
You can view plug and play connected events in Windows Defender ATP advanced hunting to identify suspicious usage activity or perform internal investigations. Microsoft Defender ATP can prevent USB peripherals from being used on devices to help prevent external threats. It does this by using the properties reported by USB peripherals to determine whether or not they can be installed and used on the device.
For examples of Windows Defender ATP advanced hunting queries, see the [Windows Defender ATP hunting queries GitHub repo](https://github.com/Microsoft/WindowsDefenderATP-Hunting-Queries).
Based on any Windows Defender ATP event, including the plug and play events, you can create custom alerts using the Windows Defender ATP [custom detection rule feature](https://docs.microsoft.com/windows/security/threat-protection/windows-defender-atp/custom-detection-rules).

### Custom Alerts and Response Actions ## Detect plug and play connected events
You can create custom alerts and response actions with the WDATP Connector and the Custom Detection Rules: You can view plug and play connected events in Microsoft Defender ATP advanced hunting to identify suspicious usage activity or perform internal investigations.
For examples of Microsoft Defender ATP advanced hunting queries, see the [Microsoft Defender ATP hunting queries GitHub repo](https://github.com/Microsoft/WindowsDefenderATP-Hunting-Queries).
The Github repository for [PowerBI Templates](https://github.com/microsoft/MDATP-PowerBI-Templates) contains sample Power BI Report templates powered by Microsoft Defender ATP advance hunting queries. The repo also includes a device control PowerBI template. With these sample templates, you can experience the integration of advanced hunting into Power BI. See [Create custom reports using Power BI](https://docs.microsoft.com/en-us/windows/security/threat-protection/microsoft-defender-atp/api-power-bi) to learn more about how to create PowerBI dashboards with advanced hunting queries.
## Custom Alerts and Response Actions
You can create custom alerts and automatic response actions with [Microsoft Defender ATP custom detection rules](https://docs.microsoft.com/en-us/windows/security/threat-protection/microsoft-defender-atp/custom-detection-rules). Microsoft Defender ATP response actions within the custom detection covers both machine and file level actions. You can also create alerts and automatic response actions using [PowerApps](https://powerapps.microsoft.com/) and [Flow](https://flow.microsoft.com/) with the [Microsoft Defender ATP connector](https://docs.microsoft.com/en-us/connectors/wdatp/). The Microsoft Defender ATP connector covers action for investigation, threat scanning, and restricting execution of applications. It is one of over 200 pre-defined connectors including Outlook, Teams, Slack, etc. Custom connectors can also be built. See [Connectors](https://docs.microsoft.com/en-us/connectors/) to learn more here about connectors.
For example, using either approach, you can automatically have the Microsoft Defender antivirus run when a USB device is mounted onto a machine.
