Discussion

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.

Check the system to determine if SCTP is installed: 

# lslpp -L bos.net.sctp
Fileset                      Level  State  Type  Description (Uninstaller)
  ----------------------------------------------------------------------------
lslpp: 0504-132  Fileset bos.net.sctp not installed.

If the "bos.net.sctp" fileset is not listed, SCTP is not installed, this is not a finding. 

If the "bos.net.sctp" fileset is listed then SCTP is installed, this is a finding.
