Embedded Firewall

June 1, 2013

Icon Labs (Des Moines, IA) and Quadros Systems (Houston, TX) recently announced the availability of Icon Labs’ Floodgate™ Packet Filter embedded firewall software for the RTXC™Quadros™ realtime operating system. Floodgate Packet Filter adds proven firewall security to Quadros-powered devices to protect from Internet-based attacks. The combined solution is designed to meet ANSI/ISA/ IEC/TS 62443 standards for cyber security. The system is designed explicitly for use in embedded devices with limited memory and processor speeds that require secure network implementation certified to standards such as the ISASP 99 which is measured by the Wurldtech Achilles™Test Platform.

Floodgate Packet Filter has been used to provide security for industrial control applications, small footprint industrial firewall appliances and MCU based control devices. It provides Stateful Packet Inspection (SPI) and rules based filtering to protect embedded devices from realworld cyber-attacks. Rules-based filtering utilizes white-listing and black-listing to define system criteria such as port number, protocol, or source IP address for protection. Floodgate also features Stateful Packet Inspection (SPI) that provides dynamic packet filtering based on the state of the connection to a device.
