Technical Details

what runs on :2394

Microsoft OLAP 2 is a legacy Analysis Services endpoint assigned to TCP and UDP 2394, although deployed OLAP traffic is primarily expected over TCP. It carries Microsoft OLAP/Analysis Services client-server communication; modern SQL Server Analysis Services commonly uses TCP 2383 for the default instance, TCP 2382 as a redirector, or dynamically configured ports instead. The protocol is proprietary rather than a simple text-based service, and this older endpoint should not be assumed to support current SSAS behavior.

security overview

An exposed endpoint may allow remote clients to discover or connect to an Analysis Services instance, subject to the server's authentication and authorization settings, potentially exposing sensitive analytical models and data. Legacy OLAP deployments should not be directly internet-facing; restrict the port to trusted application and administration networks and investigate unexpected listeners.
