Fix Recommendation

Configure OL 9 to prevent the usb-storage kernel module from being loaded.

Add the following line to the file /etc/modprobe.d/usb-storage.conf (or create usb-storage.conf if it does not exist):

install usb-storage /bin/false
blacklist usb-storage

Check Contents

Verify that OL 9 disables the ability to load the USB Storage kernel module with the following command:

$ grep -r usb-storage /etc/modprobe.conf /etc/modprobe.d/*
install usb-storage /bin/false
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.
