AIX7-00-003088 - If Stream Control Transmission Protocol (SCTP) must be disabled on AIX.

Information

The Stream Control Transmission Protocol (SCTP) is an IETF-standardized transport layer protocol. This protocol is not yet widely used. Binding this protocol to the network stack increases the attack surface of the host. Unprivileged local processes may be able to cause the system to dynamically load a protocol handler by opening a socket using the protocol.

Solution

If SCTP is installed, unload it from the kernel and uninstall it from the system using the following commands:
# sctpctrl unload
# installp -ug bos.net.sctp
