Fix Recommendation

To configure the system to prevent the tipc kernel module from being loaded, add the following lines to the file /etc/modprobe.d/tipc.conf (or create tipc.conf if it does not exist):

install tipc /bin/false
blacklist tipc

Check Contents

Verify that RHEL 9 disables the ability to load the tipc kernel module with the following command:

$ grep -r tipc /etc/modprobe.conf /etc/modprobe.d/*

install tipc /bin/false
blacklist tipc

If the command does not return any output, or the lines are commented out, and use of tipc is not documented with the information system security officer (ISSO) as an operational requirement, this is a finding.
