Disable Kernel iwlmvm Module

An XCCDF Rule

Description

To configure the system to prevent the iwlmvm kernel module from being loaded, add the following line to the file /etc/modprobe.d/iwlmvm.conf: 
install iwlmvm /bin/false
To configure the system to prevent the iwlmvm from being used, add the following line to file /etc/modprobe.d/iwlmvm.conf: 
blacklist iwlmvm

Rationale

If Wireless functionality must be disabled, preventing the kernel from loading the kernel module provides an additional safeguard against its activation.
