Technical Details
what runs on :2809CORBA clients normally communicate with the Naming Service using IIOP, the Internet Inter-ORB Protocol, over TCP. IIOP carries GIOP messages using binary CDR encoding, including requests to resolve names and return interoperable object references; the service commonly listens on TCP 2809. The registry also lists UDP, but ordinary CORBA Naming Service deployments use TCP rather than UDP. TLS-capable variants such as SSLIOP exist, but are not enabled by default.

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite
security overview
Traffic is unencrypted by default, and an exposed Naming Service may disclose object references or permit access to remotely invocable CORBA objects, depending on the server's authentication and authorization controls. It should normally be restricted to trusted application networks and monitored for vulnerable or unauthenticated CORBA implementations rather than exposed to the public internet.
