I. Product Introduction
The industrial network security system is a comprehensive security solution for protecting industrial control networks, automation equipment, and monitoring systems. It is suitable for reservoirs, sluices, pumping stations, wastewater treatment plants, water supply and drainage systems, and other industrial automation projects.
With the continuous increase in connections among PLC,LCU control cabinets,SCADA systems, and remote monitoring platforms, industrial control networks face risks such as unauthorized access, network attacks, abnormal communications, and unauthorized modification of device configurations.
By deploying industrial firewalls, network isolation devices, access control devices, and related security management components, the system manages communications between different network zones, restricts unauthorized access, and reduces the impact of network risks on on-site control equipment and engineering operations.
According to project requirements, the system can adopt measures such as zoning and isolation, boundary protection, secure remote access, communication monitoring, and log auditing to build a multi-layered network security protection system from the on-site control layer to the monitoring center.
The system can be customized according to project scale, network architecture, device types, and security requirements. It is suitable for the security design of new automation projects and can also be used for security upgrades and renovations of existing industrial control networks.
II. Main System Functions
l Network zoning and isolation: Reasonably zone the office network, monitoring network, and industrial control network to reduce unnecessary direct connections between different networks.
l Industrial firewall protection: Filter network communications according to configured security rules to restrict unauthorized access and unnecessary communications.
l Device access control: Manage access permissions for PLC,SCADA servers, engineer stations, and other critical devices.
l Secure remote access: Configure according to project requirements VPN, identity authentication, and controlled remote operation and maintenance mechanisms to reduce the security risks brought by remote connections.
l Communication monitoring and anomaly identification: Monitor network communication status according to device capabilities and identify abnormal traffic, abnormal connections, or suspicious communication behavior.
l Logging and auditing: Record information such as network access, security events, and device configuration changes according to configuration, facilitating tracing and troubleshooting.
l Critical device protection: Reduce the risk of unauthorized access to critical control devices through network isolation, access restrictions, and security policies.
l System operation assurance: Combine network architecture, device redundancy, and operation and maintenance management measures to improve the security and operational reliability of the automation system.
Specific security functions depend on the selected equipment, software authorization, system architecture, and project configuration.
III. Typical Application Scenarios
l Reservoir and dam automation control systems
l Sluice and gate remote control systems
l Pumping station and drainage project monitoring systems

IV. System Composition and Equipment Configuration
The industrial network security system can be configured with the following equipment and software according to project requirements:
1. Industrial firewall
Used to control data communications between different network zones and restrict access sources, destination addresses, ports, and allowed communication services according to security policies.
2. Network isolation and switching equipment
Including industrial switches, network zoning devices, and other network infrastructure, used to build clear network topologies and divide different security zones.
3. Secure remote access equipment
Configure according to project requirements VPN gateways, identity authentication, and controlled remote operation and maintenance equipment to support authorized personnel in accessing specified systems under prescribed conditions.
4. Network security monitoring equipment
According to project scale and security requirements, optionally equip devices or software for network traffic monitoring, abnormal communication detection, and security event logging.
5. Log audit and security management software
Used to centrally manage relevant security logs, access records, alarm information, and device configuration change records, facilitating daily management and incident tracing.
6. Network security cabinets and system integration
According to engineering needs, integrate firewalls, switches, communication equipment, and related power components into network cabinets, and connect them properly with on-site control cabinets, monitoring centers, and upper-level platforms.
Specific equipment models, quantities, brands, functions, and security level requirements are subject to project design and actual configuration.
V. Customized Services
We provide industrial network security equipment matching and system integration services for water conservancy engineering contractors, electromechanical installation enterprises, automation system integrators, and industrial project construction units.
According to the project's existing network structure, control equipment, communication methods, and security requirements, we can provide network topology planning, security device configuration, network zoning and isolation solutions, firewall policy configuration, controlled remote access design, and system commissioning services.
For water conservancy projects or industrial automation projects already in operation, we can evaluate the existing network architecture according to on-site network conditions and formulate appropriate security protection and renovation plans.
Welcome to provide existing network topology diagrams, equipment lists, communication requirements, and project security requirements to obtain an industrial network security solution and quotation suitable for your project.
