Ethernet Bridge Protects Networked Devices from Internet Attacks

SAN JOSE, Calif., April 22, 2013 – Zilog®, a wholly-owned subsidiary of IXYS Corporation (NASDAQ:IXYS), announces the introduction of the ZGATE™ Security Bridge Reference Design, a joint technology solution utilizing Icon Labs’ Floodgate™ Technology. Together, Zilog and Icon Labs have produced a microcontroller featuring an embedded firewall that provides a critical layer of security for networked devices. The new ZGATE™ Security Bridge Reference Design is a clever new approach that utilizes an embedded microcontroller and levels of protection that go beyond typical firewall security to allow smart devices to resist malevolent attacks.

Based on Zilog’s eZ80Acclaim™, embedded with Icon Labs’ Floodgate™ technology, the new ZGATE Ethernet bridge and Reference design module, will help reduce the incidence of security breaches for many types of products in defense, telecommunication, utility, transportation, medical and industrial applications.

“Zilog and Icon Labs have been working closely together on this innovative MCU-based solution to keep in step with the world’s need for stronger security solutions across many embedded applications,” said Steve Darrough, Zilog’s VP of Marketing. “ZGATE™ is the first and only embedded hardware communication solution that can protect connected devices from the growing number of Internet-based threats.”

“Icon Labs’ Floodgate technology provides protection from Internet-based threats by controlling which packets the embedded device is allowed to process,” said Alan Grau, President of Icon Labs. “Encryption and authentication may protect a device from a hacker trying to access the device, but Floodgate prevents the hacker from ever connecting. Floodgate’s filtering engine can block denial of service attacks, packet floods, port scans, or other Internet-based threats.”

Floodgate Packet Filter software adds security and firewall filtering to the RTXC Quadnet Ethernet-TCP/IP stack to protect industrial control and smart grid systems from cyber-attacks.

San Jose, California, April 22, 2013 – Icon Labs (www.iconlabs.com), a leading provider of embedded networking and security technology, and Quadros Systems (www.quadros.com) a leading provider of real-time operating systems (RTOS), today announced the availability of Icon Labs’ Floodgate™ Packet Filter embedded firewall software for the RTXC™ Quadros™ real-time operating system.

Malicious attacks on Supervisory Control and Data Acquisition (SCADA) and other industrial control and smart grid networks are a major concern. These systems were not originally built to withstand the kinds of sophisticated cyber-attacks coming from hackers, criminal enterprises and even terrorists. Recently the Industrial Control Systems Cyber Security team noted that there are now several new, publicly available exploit tools that specifically target Internet accessible industrial control system and programmable logic controllers (PLCs). Targeted systems include those from Rockwell Automation (ROK: New York), GE (GE: New York) and Schneider Electric (SU:EN Paris).

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 real-world 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.

RTXC Quadnet Ethernet-TCP/IP stack is a robust but small footprint networking solution for network-attached devices and gateways. It was built specifically for the unique needs of embedded systems but with RFC-compliance and a Berkeley sockets API. The Quadnet stack already offers advanced authentication and encryption features for IP-layer security (IPsec/IKE) and application security (SSL/TLS). The Floodgate Packet filter will add a layer of protection against threats such as packet floods, request storms, port scans, malformed IP packets and corrupted Ethernet frames.

“Network-attached embedded devices are the latest target for hackers,” says Stephen Martin, vice president, marketing at Quadros Systems. “Our customers are coming to us for new levels of security and protection against these cyber-attacks. Adding Icon Labs’ Floodgate Packet Filter to our RTX Quadnet Ethernet -TCP/IP stack provides our customers with a comprehensive defense against attack that meets today’s advanced security certification requirements.”

“Embedded devices connected to the Internet are no longer immune from hackers and other malicious threats. Attacks against embedded devices have become front page news”, said Alan Grau, President of Icon Labs. “We are excited to be working with Quadros to deliver a secure platform for industrial control and smart grid devices.”
