Technical Details

what runs on :3597

This port is assigned to the 3GPP2 A14 interface (AN-to-SC/MM), used for signaling between an access network and serving-controller mobility-management functions in HRPD networks. IANA lists both TCP and UDP; the port number alone does not establish which transport a deployment uses. It is not a general-purpose application protocol such as HTTP, and the interface's message behavior is defined by 3GPP2 rather than by a broadly deployed Internet protocol. A listener on this port is most plausibly carrier equipment or a lab/test implementation, not an ordinary host service.

routine exposure. this port is rarely the way in on its own — keep it patched and logged and move on.

network services averages 2.7 across 1,420 ports — this one sits 0.7 below.

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

security overview

A14 belongs on a controlled mobile-network signaling path, not exposed to the public Internet. Restrict access to trusted operator peers and monitor unexpected connection attempts; an exposed implementation could accept untrusted signaling even though this port is not commonly found in Internet scans. The assignment does not imply encryption, so rely on network isolation or separately configured protection rather than assuming the application traffic is encrypted.

port: :3597
service: A14 (AN-to-SC/MM)
transport: TCPUDP
encryption: cleartext
assignment: iana registered
risk: 2/10safe
category: Network Services Mobile
usage: A14 is a carrier-network signaling interface for CDMA2000 High Rate Packet Data (HRPD, or EV-DO), connecting an Access Network (AN) with Serving Controller/Mobility Management functions. It is generally relevant inside mobile operator infrastructure, not as a public-facing service.
