Fix Recommendation

Configure RHEL 10 to enable the blocking of unauthorized peripherals with the following command:

Note: This command must be run from a root shell and will create an allowlist for any USB devices currently connected to the system.

# usbguard generate-policy --no-hash > /etc/usbguard/rules.conf

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

Note: If the system is virtual machine with no virtual or physical USB peripherals attached, this is not applicable.

Verify RHEL 10 USBGuard has a policy configured.

Confirm the setting with the following command:

$ sudo usbguard list-rules
allow id 1d6b:0001 serial

If the command does not return results, or an error is returned, 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.
