Information
The Datagram Congestion Control Protocol (DCCP) is a transport layer protocol that supports streaming media and telephony. DCCP provides a way to gain access to congestion control, without having to do it at the application layer, but does not provide in-sequence delivery. If the protocol is not required, it is recommended that the drivers not be installed to reduce the potential attack surface.
Solution
# echo 'install dccp /bin/true' >> /etc/modprobe.d/CIS.conf
