3305

TCP port 3305 is assigned to odette-ftp, and RFC 5024 specifies it as the listening port for responding ODETTE-FTP entities. The RFC describes ODETTE-FTP 2, a file transfer protocol for electronic business data between trading partners. The evidence establishes the protocol’s intended role, not whether any particular host runs it or should expose it publicly.

ODETTE-FTP supports peer-to-peer transfers and communication through a Value Added Network. RFC 5024 describes authentication and optional protections including TLS session security, file encryption, signatures, and signed receipts. These are protocol capabilities; the sources do not establish which features a given implementation enables.

The RFC distinguishes ODETTE-FTP from interactive Internet FTP: it supports automated business-file exchange with acknowledgements. Port registration and protocol documentation provide no measured prevalence, deployment inventory, or malware association. Assess exposure from the system’s actual role and configuration; the available evidence does not establish an intended public audience.
