Technical Details

what runs on :6403

Port 6403 is the customary fixed TCP port for the SAP BusinessObjects Enterprise Cache Server. It carries proprietary BusinessObjects server-to-server traffic used to handle cached report content; it is not a web or other standard client-facing protocol, and its messages are not meaningfully inspected as ordinary HTTP. BusinessObjects communication settings can vary by deployment, so verify the configured server port and whether SSL is enabled rather than assuming a universal handshake or framing format.

security overview

Keep this service on trusted internal networks and restrict access to the BusinessObjects servers that need it. Its traffic is not encrypted by default in typical deployments unless SSL is configured, and exposing it publicly adds attack surface around an enterprise reporting system and potentially sensitive report data; use the platform's access controls and supported updates.
