Technical Details

what runs on :1363

The IANA assignment covers TCP and UDP 1363, but deployed Connect:Direct/NDM systems primarily use TCP for requester-to-server sessions. The requester initiates a protocol session to an NDM server, performs session and security negotiation, and transfers files through the established control and data exchange; port 1364 is the related NDM server assignment. Exact framing, authentication, and encryption depend on the Connect:Direct implementation and its Secure+ configuration rather than on the port number itself.

security overview

This port should normally be restricted to known partner hosts or private transfer networks, not exposed broadly to the Internet. An exposed listener can reveal a managed file-transfer endpoint and provide a target for authentication attacks or protocol and implementation vulnerabilities; older or misconfigured deployments may transmit sensitive transfer metadata or credentials without modern encryption. Use strong authentication, access controls, patching, and Connect:Direct Secure+ where supported.

Record

iana registry entry

port: :1363
service: Network DataMover Requester
transport: TCPUDP
encryption: cleartext
assignment: iana registered
risk: 6/10risk
category: Network Services
usage: This port is associated with the requester side of IBM Connect:Direct, formerly called Network Data Mover (NDM), an enterprise managed file-transfer protocol. In typical deployments, a Connect:Direct requester establishes a TCP session with an NDM server, commonly using port 1364 on the server side; UDP listeners are uncommon.
