Details
Check Text (C-234856r958820_chk)
Verify the SUSE operating system does not automount USB mass storage devices when connected to the host.
Check that "usb-storage" is blacklisted in the "/etc/modprobe.d/50-blacklist.conf" file with the following command:
> grep usb-storage /etc/modprobe.d/50-blacklist.conf
blacklist usb-storage
If nothing is output from the command, this is a finding.
Fix Text (F-38007r618838_fix)
Configure the SUSE operating system to prevent USB mass storage devices from automounting when connected to the host.
Add or update the following line to the "/etc/modprobe.d/50-blacklist.conf" file:
blacklist usb-storage
