Who does this work

7 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

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.
