Fix Recommendation

To configure the system to prevent the "firewire-core" kernel module from being loaded, add the following line to the file /etc/modprobe.d/firewire-core.conf (or create firewire-core.conf if it does not exist):

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

Check Contents

Verify TOSS 5 disables the ability to load the "firewire-core" kernel module using the following command:

$ sudo grep -r firewire-core /etc/modprobe.conf /etc/modprobe.d/*

blacklist firewire-core

If the command does not return any output, or the line is commented out, and use of firewire-core is not documented with the information system security officer (ISSO) as an operational requirement, this is a finding.
