sensitive, about the wireless network. For this reason, Emerson encourages end users to
use Emerson’s Security Setup Utility to secure the industrial protocols. Users running non-
secure versions of the industrial protocols are encouraged to make sure the Gateway is
running on a secure network and following security best practices.
The Security Setup Utility enables secure communications between the Gateway and host
system, asset management software, data historians, or other applications. This is done by
encrypting the standard data protocols (AMS Wireless Configurator, Modbus TCP,
Ethernet/IP
™
, and OPC) used by the Gateway and making them available through various
proxies within the Security Setup Utility. These proxies can function as a data server for
other applications on the control network. The Security Setup Utility can support multiple
Gateways at once and each proxy can support multiple client application connects. Figure
4-1 shows a typical system architecture using the Security Setup Utility.
