USBGuard is a framework that enforces USB device authorization and usage policies to protect endpoints from unauthorized USB device interactions.
USBGuard is a software framework for implementing USB device authorization policies (what kind of USB devices are authorized) as well as method of use policies (how a USB device may interact with the system)
USBGuard is primarily used by system administrators and security professionals to control which USB devices can connect to a system and define how these devices interact with the system. It helps prevent unauthorized access or data exfiltration via USB devices by enforcing strict device authorization policies on endpoints.
USBGuard requires root or administrative privileges to manage USB device policies and interact with system services. Proper configuration and testing are essential to avoid accidentally blocking legitimate devices. Integration with systemd is recommended for managing the USBGuard daemon lifecycle.
Clone the repository or download the source code from GitHub
Install dependencies as specified in the documentation (e.g., libusb, systemd)
Build the software using the provided build system (e.g., make)
Install the compiled binaries and configuration files to the system
Enable and start the USBGuard service using systemd or equivalent init systemusbguard daemon
Starts the USBGuard daemon which enforces the USB device authorization policies.

Lists all USB devices currently connected to the system along with their authorization status.
usbguard allow-device <device-id>
Authorizes a specific USB device to interact with the system.
usbguard deny-device <device-id>
Blocks a specific USB device from interacting with the system.
usbguard generate-policy
