Firewall Appliance for Critical Infrastructure Equipment

May 25, 2016 by Jeff Shepard

Icon Labs announces availability of the low cost and easy to install Floodgate Defender firewall appliance. The compact Floodgate Defender Mark III (4 inches by 3.75 inches by 1.25 inches) provides a critical layer of security for legacy devices that comprise The Internet of Things including SCADA networks, military equipment, critical infrastructure controllers, and medical devices.

“A large portion of our critical infrastructure is controlled by legacy devices that were originally designed for use on closed networks and therefore contain little or no security. Even though they perform critical functions managing our power grid, factories, communication networks, and hospitals, most are easy targets for cyber-criminals and cyber-terrorism,” said Alan Grau, President of Icon Labs. “Many of these devices cannot be updated to include security, and replacing them with new secure versions will take years. The Floodgate Defender provides a simple and cost-effective solution to stop these attacks.”

The Floodgate Defender device is plugged in between the Internet or WAN and the device. It includes two Ethernet ports for easy installation. It can be easily configured with communication policies customized for the device it is protecting by using a web-based management interface. The Floodgate Defender enforces the policies, blocking attacks before a connection can be established with the target device, without requiring any change to the network or the target device. The Floodgate Security Manager, or other security management systems, can access the event log to audit and manage policies.

The Floodgate Defender’s patented technology protects legacy devices from a broad range of cyber-attacks. Features include: Filtering by IP addresses, ports, and protocols; Stateful packet inspection; Deep packet inspection for ModbusTCP and other industrial protocols; Detection and reporting of suspicious traffic; Integration with security management systems including Floodgate Security Manager, McAfee ePO and McAfee SIEM; and Ethernet pass-through upon power failure to facilitate continuous operation in critical environments.

The Floodgate Defender includes an innovative security coprocessor from Maxim Integrated Products, Inc. that provides secure key storage and a cryptographic accelerator. This improves the resistance of encryption functions, enables secure boot, and ensures the security of both the Floodgate Defender device itself and the devices it is protecting.

“We are pleased to partner with Icon Labs to incorporate our secure microcontroller into this new compact firewall that protects installed networked devices with insufficient security. This exclusive combination of our technology with Icon Labs’ software is a significant advancement in creating the “Internet of Secure Things,” said Christophe Tremlet, Senior Business Manager, Maxim Integrated.
