Fix Recommendation

Configure the operating system to disable the ability to use the firewire-core kernel module.

Add or update the following lines in the file "/etc/modprobe.d/blacklist.conf":

install firewire-core /bin/false
blacklist firewire-core

Reboot the system for the settings to take effect.

Check Contents

Verify the operating system disables the ability to load the firewire-core kernel module and ensure that the firewire-core kernel module is disabled with the following command:

$ sudo grep -r firewire-core /etc/modprobe.d/* | grep "blacklist"

/etc/modprobe.d/blacklist.conf:install firewire-core /bin/false
/etc/modprobe.d/blacklist.conf:blacklist firewire-core

If the command does not return any output, or the line is commented out, and use of the firewire-core protocol is not documented with the Information System Security Officer (ISSO) as an operational requirement, this is a finding.
