Technical Details

what runs on :5990

WBEM export uses HTTP requests carrying CIM-XML export operations, such as ExportIndication, to deliver indications to a listener. On this HTTPS assignment, the normal transport is TCP with TLS; HTTPS is not ordinarily carried over UDP, despite UDP also appearing in the registry assignment. Related WBEM ports include 5988 for HTTP and 5989 for HTTPS CIM operations.

security overview

TLS protects the connection in normal HTTPS deployments, but an exposed listener accepts data pushed by remote WBEM systems and may reveal operational or management information. Keep it private or restrict it to trusted WBEM servers, and use appropriate authentication and certificate validation.
