Check Text (C-275631r1147943_chk)
Verify Ubuntu OS disables ability to load the USB storage kernel module by using the following command:
$ grep usb-storage /etc/modprobe.d/* | grep "/bin/false"
/etc/modprobe.d/stig.conf:install usb-storage /bin/false
If the command does not return any output, or the line is commented out, this is a finding.
Verify Ubuntu OS disables the ability to use USB mass storage device.
$ grep usb-storage /etc/modprobe.d/* | grep -i "blacklist"
/etc/modprobe.d/stig.conf:blacklist usb-storage
If the command does not return any output, or the line is commented out, this is a finding.
Fix Text (F-79638r1147942_fix)
Configure Ubuntu OS to disable using the USB storage kernel module.
Create and/or append a custom file under "/etc/modprobe.d/" to contain the following:
$ sudo su -c "echo install usb-storage /bin/false >> /etc/modprobe.d/stig.conf"
Configure Ubuntu OS to disable the ability to use USB mass storage devices.
$ sudo su -c "echo blacklist usb-storage >> /etc/modprobe.d/stig.conf"
