Installing and Configuring USBGuard

In this lab, we'll be setting up USBGuard to to control which USB devices are allowd to communicate with our hosts once they are plugged in. USB devices are an easy way for attackers to gain a foothold in our environments via USB Dropper attacks. USBGuard is a great security control that can help us avoid being infected by a malicious USB device. *This course is not approved or sponsored by Red Hat.*
