HST Agent to HST Server
HST Servers do not initiate communications to HST Agents, all communication is initiated by the HST Agent to the HST Server. For this interaction, the following ports are used:
| Source Component | Destination Component | Destination Port | Transport Security | Purpose |
|---|---|---|---|---|
| HST Agent | HST Server | tcp/9440 | One-way SSL | Agent Registration |
| HST Agent | HST Server | tcp/9441 | Two-way SSL | Anonymized bundle transfer |
HST Agents register themselves with the HST Server, and when invoked to capture data use the same port to securely transmit captured data back to the HST Server.
