Disable IEEE 1394 (FireWire) Support

An XCCDF Rule

Description

The IEEE 1394 (FireWire) is a serial bus standard for high-speed real-time communication. 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: 

install firewire-core /bin/false
To configure the system to prevent the firewire-core from being used, add the following line to file /etc/modprobe.d/firewire-core.conf: 
blacklist firewire-core

Rationale

Disabling FireWire protects the system against exploitation of any flaws in its implementation.
