Fix Recommendation

To configure the system to prevent the TIPC kernel module from being loaded, run the following command:

$ cat << EOF | tee /etc/modprobe.d/tipc.conf
install tipc /bin/false
blacklist tipc
EOF

Check Contents

Verify that AlmaLinux OS 9 disables the ability to load the TIPC kernel module with the following command:

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

/etc/modprobe.d/tipc.conf:install tipc /bin/false
/etc/modprobe.d/tipc.conf:blacklist tipc

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