Description

The Transparent Inter-Process Communication (TIPC) protocol is designed to provide communication between cluster nodes.

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.

Audit Procedure

Run the following commands and verify the output is as indicated:

modprobe -n -v tipc
# Expected: install /bin/true

lsmod | grep tipc
# Expected: <No output>

Expected Result

install /bin/true

And no output from lsmod | grep tipc.

Remediation

Edit or create the file /etc/modprobe.d/CIS.conf and add the following line:

install tipc /bin/true

Default Value

Not disabled by default.
