3.1.3 Ensure DCCP is disabled - modprobe

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 a file in the /etc/modprobe.d/ directory ending in .conf

Example:

printf '
install dccp /bin/true
' >> /etc/modprobe.d/dccp.conf
