1.1.1.9 Ensure firewire-core kernel module is not available

Information

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

Unload and disable the firewire-core kernel module.

- Run the following commands to unload the firewire-core kernel module:

# modprobe -r firewire-core 2>/dev/null
# rmmod firewire-core 2>/dev/null
- Perform the following to disable the firewire-core kernel module:

Create a file ending in .conf with install firewire-core /bin/false in the /etc/modprobe.d/ directory

Example:

# printf '%s\n' \"\" \"install firewire-core /bin/false\" >> /etc/modprobe.d/60-firewire-core.conf

Create a file ending in .conf with blacklist firewire-core in the /etc/modprobe.d/ directory

Example:

# printf '%s\n' \"\" \"blacklist firewire-core\" >> /etc/modprobe.d/60-firewire-core.conf
