Technical Details

what runs on :9088

The Informix SQL Interface uses IBM's SQLI wire protocol over TCP and, according to the registry assignment, UDP. The conventional service name is sqlexec and the commonly associated port is 9088, although Informix deployments can select another service name or port in their network configuration. The protocol is proprietary rather than a generic SQL protocol, and clients must use Informix-compatible drivers or tools.

security overview

An exposed listener may provide access to an Informix database after authentication and can disclose database metadata or permit SQL operations depending on account privileges. It should normally be restricted to application and administration networks; legacy deployments may not encrypt SQLI traffic by default, so internet exposure risks credential and data interception as well as attack-surface enumeration.
