Disable SCTP Support

An XCCDF Rule

Description

The Stream Control Transmission Protocol (SCTP) is a transport layer protocol, designed to support the idea of message-oriented communication, with several streams of messages within one connection. To configure the system to prevent the sctp kernel module from being loaded, add the following line to the file /etc/modprobe.d/sctp.conf:

install sctp /bin/true

To configure the system to prevent the sctp from being used, add the following line to file /etc/modprobe.d/sctp.conf:

blacklist sctp

Rationale

Disabling SCTP protects the system against exploitation of any flaws in its implementation.
