Modbus Protocol filter gives cyber attack protection for industrial automation & control systems

Icon Labs has announced the release of its Floodgate Modbus Protocol Filtering product. This extension to Icon Labs’ Floodgate Security Framework adds critical protection capabilities for Industrial IoT and RTOS-based devices.

The Floodgate Modbus Protocol filter provides the critical missing layer of security for Modbus/TCP devices. Integrated into the device, Floodgate Modbus Protocol filtering utilizes deep packet inspection to enforce virtual network segmentation and to control packets processed based upon source network address, function code, and packet data contents.

Floodgate Modbus Protocol filtering is an extension of the Floodgate Firewall, an endpoint firewall solution designed for embedded and RTOS-based systems. The solution integrates with the native TCP/IP stack on the device and provides control over the packets processed by the device. The Modbus Protocol filtering extension provides control over the Modbus packets processed by the device based upon Modbus function code, originating IP address, or Modbus packet content. Integration with the Floodgate Agent enables detection and reporting of malicious traffic.

Icon Labs’ Floodgate Security Framework is a comprehensive security solution for embedded devices providing security management, secure boot, intrusion detection, secure firmware updates, and an embedded firewall. These capabilities provide the building blocks for achieving EDSA certification, ISA/IEC 62443 compliance, and/or compliance with the NIST cybersecurity framework.

Icon Labs’ products provide embedded security for IoT and Machine to Machine (M2M) solutions such as aerospace, military and space probes, industrial and medical control devices, and consumer electronics products. The Floodgate Security Framework provide a “defense in depth” solution to protect control units and endpoint devices from cyber threats, aid in compliance with regulatory mandates and guidelines, and gather and report command, event and device status information for audit requirements.
