H3C SecPath F3000 OT Firewall

The H3C OT Firewall is a security protection product developed and launched by New H3C Technologies Co., Ltd. for industrial control networks. It includes functions such as traditional firewall, intelligent learning of industrial control network traffic, deep resolution of industrial control protocol packets, and control of industrial control protocol commands.

Based on flow sessions, the H3C OT Firewall implements stateful inspection firewall functionality, intelligently detects TCP traffic state information, and performs control. It smartly conducts application layer inspection and opens dynamic ports, creating and deleting security policy rules for data packets targeting dynamically negotiated ports to allow or block relevant messages, adhering to the principle of security minimization.

The H3C OT Firewall supports various network security protection technologies, including VPN, NAT, and DoS attack protection. It provides access control, connectionless integrity, data source authentication, anti-replay, encryption, and traffic classification encryption services through IPSec VPN. It offers rich address translation services through SNAT and DNAT and supports various DoS attack protection features such as SYN-FLOOD and UDP-FLOOD. For industrial control networks and systems, the H3C OT Firewall supports deep resolution of mainstream industrial control network protocols, including Modbus/TCP, OPC Classic, OPC UA, DNP3, S7, S7 plus, IEC60870-5-104, MMS, and Ethernet/IP. Additionally, it intelligently protects industrial control traffic and provides command-level control based on an industrial control network whitelist. Furthermore, the firewall integrates an industrial control vulnerability database and an industrial control intrusion detection signature database to detect and block attacks and intrusion behaviors in the industrial control network using denylist technology.
