# 3.5.4 Ensure TIPC is disabled | |
# | |
# 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 | |

# Run the following commands and verify the output is as indicated: | |
# | |
# # modprobe -n -v tipc | |
# install /bin/true | |
# # lsmod | grep tipc | |
# <No output> | |
# | |
# Remediation | |
# =========== | |
# | |
# Edit or create the file /etc/modprobe.d/CIS.conf and add the following line: | |
# | |
# install tipc /bin/true | |
