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.
Parameter:
[disable/disable with error logged/enable]
Technical Mechanism:
# echo install dccp /bin/true /etc/modprobe.d/dccp.conf
