The remote host is running the Financial Information eXchange (FIX) protocol.
The remote client is running a Financial Information eXchange (FIX) application. This protocol is used by financial institutions to exchange data. The FIX protocol has very few built-in security controls and, instead, relies on industry standard encryption (PGP, SSL/TLS, etc.) to protect the stream.
Ensure that FIX data is encrypted when passed over untrusted networks.
