Technical Details

what runs on :6464

SDC uses web-service protocols for medical-device communication, including SOAP 1.2 and WS-* specifications. IANA lists both TCP and UDP for this assignment; device service exchanges on port 6464 are typically SOAP over HTTP(S) on TCP. WS-Discovery commonly uses multicast UDP on port 3702 for discovery, rather than carrying the main service exchanges on 6464. SDC deployments use TLS for protected connections, though the actual configuration depends on the implementation.

4/ 10caution

worth attention. how exposed you are depends on configuration — don't leave it reachable from the internet without a reason.

iot averages 3.4 across 172 ports — this one sits 0.6 above.

tcp · udp

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite

security overview

This is a specialized medical-device interface, not a service intended for unrestricted internet access. If exposed, it may reveal device or patient-related information and provide access to device service operations; restrict it to the clinical network and verify TLS, certificates, and authorization in the specific deployment.
