Appendix A. Tivoli Firewall Security Toolbox overview 179
Sending events across firewalls
Tivoli adapters use Endpoints to send events to the TEC Server through Tivoli
connections. When the firewall separates the Endpoint from the TEC server, the
machines connect through the Gateway and Endpoint Proxies. Machines that
are not part of the Tivoli environment use non-TME adapters to send events to
TEC servers through non-Tivoli connections.
When the firewall separates the non-TME adapter machine from the Gateway,
TFST provides the Event Sink, which sends the events to the TEC server. The
Event Sink, which is installed on an Endpoint outside the firewall, collects the
events sent from non-TME adapters as if it were a TEC server and sends them to
the TEC server as though they were TME events. Figure A-3 shows the Event
Sink collecting events from non-TME adapters and sending them to the TEC
server through the firewall.
