Tofino™ Security Appliance Firmware Update Process

The Tofino Security Appliance is a self-contained microprocessor-based device that provides firewall, VPN, asset management, event logging and other security services in control and automation networks. Its functionality is determined by firmware stored in non-volatile memory inside the appliance.

As part of the ongoing development and enhancement of the product, Byres Security periodically releases firmware updates that may be installed in the appliance using the Tofino Central Management Platform (CMP) software.

This document describes how to use the Tofino CMP to install these firmware updates, and also how to manage the potential impact of this update process on the operation of the plant protected by the Tofino Security Appliance (SA).
