Technical Details

what runs on :12005

DBISAM uses a proprietary database client/server protocol rather than HTTP or a standard wire protocol. The registered service uses TCP and UDP port 12005; DBISAM deployments most commonly use the port for client connections to the database server, while exact UDP behavior depends on the DBISAM version and configuration. The protocol is application-specific and is not interchangeable with PostgreSQL, MySQL, or other database protocols.

security overview

This port can provide remote access to application data and should not be exposed directly to the public internet. Restrict it to trusted application hosts and networks using firewall rules; the DBISAM protocol should not be assumed to provide modern transport encryption, so sensitive deployments should use a protected network or tunnel. An exposed listener may allow authentication attacks, database enumeration, or unauthorized access if application credentials or server controls are weak.
