Enhanced perimeter defence solution

August 2023 PLCs, DCSs & Controllers

Emerson is improving perimeter security for the DeltaV distributed control system (DCS) with its new NextGen Smart Firewall, a purpose-built control system firewall designed to provide easy-to-install and maintain perimeter security for all industries. More ruggedised construction, increased bandwidth, and role-based access provide users with increased performance and more granular access control.

Manufacturers need to secure their networks without the complexity that would otherwise add administrative overhead to already busy operations teams. Emerson’s NextGen Smart Firewall features a user-friendly HTML5 web-based user interface, easy to understand setup menus, and pre-defined DeltaV application rules. The ease of use helps DeltaV administrators and control engineers with no security or IT expertise create secure connections for DeltaV applications.

“A critical element of Emerson’s vision of boundless automation architecture is secure connectivity between systems in the plant and across the enterprise,” said Claudio Fayad, vice president of technology for Emerson’s process systems and solutions business. “Emerson’s NextGen Smart Firewall delivers intuitive setup and interfaces to provide plants with access to a much wider array of technologies, from control to reliability to sustainability and more, without the need to maintain a dedicated IT presence.”

Gigabit connections support improved performance for applications that require higher bandwidth. Ruggedised construction is well suited for harsh manufacturing environments. Advanced features include:

• Virtual private networks for increasing flexibility and security for geographically dispersed networks.

• Network address translation for protecting network IP schemes and conserving addresses.

• More granular user roles so that administrators have full control, engineers may add or modify application rules, and auditors have read-only access to logs.
