Tofino Industrial Control Systems Information Security Solutions are specifically designed for industrial communications such as SCADA and process control systems to provide a zoned security solution. Tofino is extremely cost-effective and has the ability to build a deep protection architecture in the factory floor so that even hackers or viruses pass through the main corporate firewall they will face specialized security equipment designed on the basis of the control network, These devices can then cause damage.
The Tofino module is centrally configured, configured and managed using the Tofino Central Management Platform (CMP), which can be used remotely or even across national borders. The control system or enterprise network can be installed with CMP in place. Using CMP and loading all the necessary Loadable Security Modules (LSMs), the Tofino modules can be adjusted online in real time to meet the safety requirements of the protected area and equipment.

Tofino soft-plug-in LSM provides factory-specific security solutions such as encryption, intrusion detection and control protocol identification. For example, one of the Tofino hardware can be used as the firewall for a proprietary PLC control system network and the other Tofino hardware as an encryption system for network RTU communication. Of course, a single Tofino hardware can load multiple soft-plug LSMs simultaneously, while providing multiple security protections.
Tofino Security System, on the one hand, is a complete, distributed security solution that, on the other hand, can be centrally managed simply and securely, making it a unique product. For large industrial enterprises, Tofino Security System means the best security benefits and technical support, not just to meet the security needs of independent critical control system equipment.
Unlike traditional IT firewalls, Tofino is designed to control network communications security requirements in industrial environments. Field technicians simply plug in the Tofino power supply and connect the two network cables without any further action. Once installed, security / technicians can manage any system effortlessly and respond to cyber threats in a manner that takes the overall picture of the company. Most importantly, Tofino can be used flexibly both in small plants that are simply PLCs and for large multinationals that have thousands of devices and are distributed around the world.
Program structure
A complete Tofino industrial control system information security solution consists of four parts:
Tofino Security Modules (TSAs) - Enhanced industrial environments require design, plug and play, and application to critical devices such as protected areas or controllers . The figure below shows the Tofino Security Module Hardware (TSA-220):
Tofino Loadable Security Plug-In (LSM) - A security soft-plug-in designed for industrial communication protocols that provides security services such as industrial communications firewalls, event and alarm management, OPC / Modbus TCP deep communication inspection, secure device asset management, Encryption and so on. The LSM can be loaded directly into the Tofino Security Module and provide a variety of custom security services based on system requirements.
Tofino Central Management Platform (CMP) - Windowed central management platform system and database for configuration, configuration and management of Tofino security modules
Tofino Security Management Platform (SMP) - Windows-based security management platform system and database for unified management of real-time data and alarm information of all SMP-connected CMPs and TSAs. It can be used for office network monitoring, access and storage of real-time data and alarm information .

Program achieved the goal
Zone Isolation: The Tofino Industrial Firewall Plug-in filters traffic between two regional networks, which means that network failures are controlled within the original zone without affecting other parts.
Communication Control: Communication rules are preconfigured and tested online via CMP.
Real-time Alarms: Any illegal (unconfigured) access generates real-time alarm information on the CMP management platform and can be notified by email or SMS via hardware and software such as Syslog Server (optional) The problem will be quickly found and solved in the original area
Once and for all: industrial hardware design, to ensure the stability of the module; unique proprietary control protocol inspection design concept (white list concept), bid farewell to the traditional firewall virus database upgrades and other cumbersome work in the protection without changing the control system Network original application software operation mode, greatly reduce the control system network maintenance.
