Title

RHEL 9 must be configured to disable the FireWire kernel module. (Cat II impact)

Discussion

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

Check Content

Verify that RHEL 9 disables the ability to load the firewire-core kernel module with 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.

Fix Text

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
