# WHATPORT(9593)

## NAME

port 9593 — cba8 — LANDesk/Ivanti Management Agent — The LANDesk (Ivanti Endpoint Manager) CBA8 agent listener, first of the 9593-9595 trio on managed endpoints.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA registered 9593 as `cba8`, "LANDesk Management Agent (cba8)", in 2010. CBA8 is the common base agent that the LANDesk / Ivanti Endpoint Manager core server talks to for inventory, software distribution, and policy. It is almost always seen together with 9594 and 9595, which are registered to the same product family, so the three appearing side by side is a reliable fingerprint for a managed Windows estate. A single open 9593 with nothing else usually means a leftover agent on a decommissioned machine.

## EXPOSURE

**Do not expose.** A management agent accepts instructions from a core server, which makes it a software-deployment channel. Restrict it to the management network.

## CHECK

```sh
sudo lsof -nP -iTCP:9593 -sTCP:LISTEN
```
