InformationThe 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.
SolutionEdit or create a file in the /etc/modprobe.d/ directory ending in .conf
Example: vim /etc/modprobe.d/dccp.conf
