OL08-00-040026 - OL 8 must disable IEEE 1394 (FireWire) Support.

Information

It is detrimental for operating systems to provide, or install by default, functionality exceeding requirements or mission objectives. These unnecessary capabilities or services are often overlooked and therefore may remain unsecured. They increase the risk to the platform by providing additional attack vectors.

The IEEE 1394 (FireWire) is a serial bus standard for high-speed real-time communication. Disabling FireWire protects the system against exploitation of any flaws in its implementation.

Solution

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.
