# WHATPORT(5102)

## NAME

port 5102 — Oracle OMS non-secure — Registered to Oracle's Management Server in its non-secure mode — cleartext management traffic.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA registers 5102 as oms-nonsecure, "Oracle OMS non-secure", the unencrypted channel for Oracle's Management Server component of Enterprise Manager. The name is explicit about what it is: the same management traffic as the secure variant, without TLS. Modern Enterprise Manager deployments use HTTPS upload and console ports instead, so a listener here suggests an old or misconfigured install.

## EXPOSURE

**Do not expose.** A cleartext management channel to a database estate. Disable it in favour of the secure port; anything on the path can read the traffic.

## CHECK

```sh
nc -vz TARGET 5102
```
