3.4.1 Ensure DCCP is disabled - grep modprobe.d

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.

Rationale:

If the protocol is not required, it is recommended that the drivers not be installed to reduce the potential attack surface.

Solution

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

install dccp /bin/true
