Description
Disabling firewire protects the system against exploitation of any flaws in its implementation.
ℹ️ Check
Verify that OL 9 disables the ability to load the firewire-core kernel module with the following command:
$ grep -r firewire-core /etc/modprobe.conf /etc/modprobe.d/*
install firewire-core /bin/true
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.
✔️ Fix
Configure OL 9 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/true
blacklist firewire-core
