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. Options Explained: disable - would disable the module. disable with error logged - would disable the module and log whenever module is inserted. enable - would enable the module. 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. Fix: # echo install sctp /bin/true >> /etc/modprobe.d/sctp.conf

[disable/disable with error logged/enable]

# echo install sctp /bin/true /etc/modprobe.d/sctp.conf
