This audit message means an incoming or outgoing TCP/IP connection was successfully established. This does not indicate the corresponding user was permitted to use the service - just that they were not rejected. Typically, each service implements additional authentication mecha- nisms specific to the service type (DICOM, HTTP etc.).

This message can be used to report on external hosts communicating with the system, and to correlate higher level protocol messages back to the IP address initiating the activity. The “Connection Identifier” field allows correlation of audit messages related to actions performed during a session.
