Cross-Platform USB Monitoring Policy

Monitor and alert when a USB device is inserted across Windows, macOS, and Linux. Ideal for high-security environments, it’s easy to deploy and pairs with automated remediation for enhanced protection.

Problem overview.

The challenge this resource is designed to solve.

USB devices pose significant security risks, including data theft, malware introduction, and unauthorized file transfers. Monitoring USB activity is crucial for securing sensitive environments and ensuring compliance with security protocols.

About this resource.

What it does and how it fits into your workflow.

The Cross-Platform USB Monitoring Policy continuously tracks USB device activity across Windows, macOS, and Linux systems. It immediately generates alerts when a USB device is inserted into a tagged device. Designed with simplicity in mind, this monitor requires no custom coding—just add the “USB” tag to the devices you want to secure, and the policy does the rest. For added protection, pair it with automation to eject or wipe unauthorized devices.
