Check Text (C-230503r1069316_chk)
Verify the operating system disables the ability to load the USB Storage kernel module and ensure that the USB Storage kernel module is disabled with the following command:
$ sudo grep usb-storage /etc/modprobe.d/* | grep -i "blacklist"
/etc/modprobe.d/blacklist.conf:install usb-storage /bin/false
/etc/modprobe.d/blacklist.conf:blacklist usb-storage
If the command does not return any output, or the line is commented out, and use of USB Storage is not documented with the Information System Security Officer (ISSO) as an operational requirement, this is a finding.
Fix Text (F-33147r942935_fix)
Configure the operating system to disable the ability to use the USB Storage kernel module and the ability to use USB mass storage devices.
Add or update the following lines in the file "/etc/modprobe.d/blacklist.conf":
install usb-storage /bin/false
blacklist usb-storage
Reboot the system for the settings to take effect.
