The Transparent Inter-Process Communication (TIPC) protocol is designed to provide communication between cluster nodes.
Options Explained:
disable - would disable the module.
disable with error logged - would disable the module and log whenever module is inserted.
enable - would enable the module.
Rationale:
If the protocol is not being used, it is recommended that kernel module not be loaded, disabling the service to reduce the potential attack surface.
Fix:
# echo install tipc /bin/true >> /etc/modprobe.d/tipc.conf
Parameter:
[disable/disable with error logged/enable]
Technical Mechanism:
# echo install tipc /bin/true /etc/modprobe.d/tipc.conf
