Information
The Stream Control Transmission Protocol (SCTP) is a transport layer protocol used to
support message oriented communication, with several streams of messages in one
connection. It serves a similar function as TCP and UDP, incorporating features of both. It is
message-oriented like UDP, and ensures reliable in-sequence transport of messages with
congestion control like TCP.
*Rationale*
If the protocol is not being used, it is recommended that kernel module not be loaded,
disabling the service to reduce the potential attack surface.
Solution
# echo 'install sctp /bin/true' >> /etc/modprobe.d/CIS.conf
