Technical Details

what runs on :7574

The IANA assignment is TCP/7574 for the Oracle Coherence Cluster Service. Coherence uses this port as its conventional cluster port, but its usual TCMP cluster messaging is UDP-based; TCP/7574 should therefore be interpreted in the context of the configured Coherence deployment, not as a universal TCP handshake or framing standard. Coherence*Extend client connections are a separate use and commonly use TCP port 20000 by default.

security overview

Keep cluster communication on trusted, restricted networks rather than exposing it to the internet. A reachable Coherence cluster endpoint can expose sensitive in-memory data or cluster operations to an untrusted peer, depending on configuration; cluster traffic is not encrypted by default, so use supported security and encryption settings where appropriate.

Record

iana registry entry

port: :7574
service: Oracle Coherence Cluster Service
transport: TCP
encryption: cleartext
assignment: iana registered
risk: 7/10risk
category: Databases Network Services
usage: Oracle Coherence is an in-memory data grid, and 7574 is its conventional cluster port for communication between cluster members. Coherence commonly uses UDP for cluster messaging, so an open TCP/7574 listener depends on the deployment's configuration rather than being universal.
