Fix Recommendation

Configure the operating system to enable the blocking of unauthorized peripherals with the following commands:

$ sudo systemctl enable usbguard.service

$ sudo systemctl start usbguard.service

Note: Enabling and starting usbguard without properly configuring it for an individual system will immediately prevent any access over a usb device such as a keyboard or mouse.

Check Contents

Verify the operating system has enabled the use of the USBGuard with the following command:

$ sudo systemctl status usbguard.service

usbguard.service - USBGuard daemon
Loaded: loaded (/usr/lib/systemd/system/usbguard.service; enabled; vendor preset: disabled)
Active: active (running)

If the usbguard.service is not enabled and active, ask the SA to indicate how unauthorized peripherals are being blocked.

If there is no evidence that unauthorized peripherals are being blocked before establishing a connection, this is a finding.
