Disable SCTP
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.
Parameter:
[no/yes]
Technical Mechanism:
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.
Fix:
"# echo ""install sctp /bin/true"" >> /etc/modprobe.d/CIS.conf"
