Pamamahala at Pagpapatupad ng Cybersecurity para sa mga System ng Pagsusuri ng Wind Farm

Sa pag-unlad ng industriya ng wind power, ang mga sistema ng pang-monitoring ng kuryente sa mga wind farm ay naging isang mahalagang suporta para sa operasyon ng grid. Gayunpaman, habang lumalaki ang antas ng informatization at intelligence, ang mga banta sa cybersecurity ay naging mas malubha—lalo na sa mga sektor ng critical infrastructure, kung saan ang mga requirement para sa cybersecurity ay mas mahigpit kaysa sa anumang oras.

1. Puntong Pagsubok na Hinaharap ng Mga Sistema ng Pang-monitoring ng Kuryente sa Wind Farm

• Lumalaking Banta sa Cybersecurity:Ang mga malicious attacks tulad ng mga virus, trojans, at ransomware ay patuloy na tumataas.

• Insufficient Zone Isolation:Hindi sapat na isolation at access control sa pagitan ng production control zone at management information zone maaaring magresulta sa lateral threat propagation.

• Hindi Sapat na Seguridad sa Data Transmission:Ang data transmission sa loob ng sistema ng monitoring at sa upper-level dispatch centers nangangailangan ng mas matibay na encryption at security mechanisms.

• Kakulangan sa Endpoint Protection:Ang mga engineering workstations, operator stations, at iba pang endpoint devices ay vulnerable at madalas ginagamit bilang entry points para sa cyberattacks.

Upang harapin ang mga hamon na ito, ang proyektong ito ay sumusunod sa principle ng cybersecurity protection na "Security Zoning, Dedicated Network, Horizontal Isolation, Vertical Authentication", kasama ang framework na "One Center, Three Layers of Defense", upang makabuo ng comprehensive na cybersecurity protection architecture.

2. Application at Deployment ng Intelligent Networking Devices

Sa proyektong ito, ang intelligent networking devices ay nagsisilbing isang core component. Ang kanilang mataas na performance, flexible networking capabilities, at industrial-grade design ay nagbibigay ng matibay na suporta para sa seguridad ng mga sistema ng pang-monitoring ng kuryente sa wind farm.

Key Technical Features ng Intelligent Networking Devices

• High-Speed Data Connectivity: Suportado ng 5G at Wi-Fi 6 technologies, may maximum transmission rates na hanggang 1800 Mbps, na nasasaklaw ang high-bandwidth, low-latency communication needs ng mga wind farm.

• Industrial-Grade Design: Operates within a temperature range of -20°C to 70°C, suitable for harsh wind farm environments.

• Flexible Networking: Suportado ng distributed wireless networking at VLAN functionality, na nagbibigay ng secure zoning at logical isolation.

• Expandability and Compatibility: Equipped with USB, M.2 interfaces, at multiple network ports, supporting future device expansion and upgrades.

• Secure Data Transmission: Built-in encryption modules ensure the security of communication links.

Deployment Strategy

• Production Control Zone: Deployed in the wind farm control center, providing high-speed connectivity and integrated with other security devices (e.g., industrial firewalls) to protect the production control network.

• Management Information Zone: Utilizes VLAN and logical isolation features to securely separate from the production control zone, preventing cross-zone threat propagation.

• Remote Monitoring Support: Enables secure communication with the upper-level dispatch system via 5G networks, ensuring stable and reliable data transmission.

3. Integrated Cybersecurity Protection System Design

By integrating intelligent networking devices with other security components, the following protection framework was designed:

3.1 Secure Communication Network

Leveraging high-speed 5G and Wi-Fi 6 technologies provided by the networking devices, internal and external data transmission is made secure and reliable. Combined with VPN technology, a dedicated channel is established for remote maintenance, preventing data leakage.

3.2 Secure Zone Boundaries

Industrial firewalls and security isolation gateways are deployed between the production control zone and the management information zone. Combined with the VLAN capabilities of the networking devices, this achieves a hybrid approach of physical and logical isolation for robust zone boundary protection.

3.3 Secure Computing Environment

Industrial host protection software is installed on engineering and operator workstations, enabling whitelist policies and peripheral device control to prevent malware infiltration.

3.4 Security Management Center

A cybersecurity monitoring system continuously analyzes network traffic and security events, performing log analysis and event correlation to enable centralized, unified security management.

4. Effectiveness Evaluation

• Significantly Enhanced Network Security: The multi-layered defense system effectively prevents viruses, trojans, and other malicious attacks.

• More Reliable Data Transmission: High bandwidth and low latency of the networking devices ensure stable internal and external data transmission.

• Regulatory Compliance Achieved: Successfully passed China’s Cybersecurity等级 Protection (Level Protection) Assessment, meeting national cybersecurity regulatory requirements.

5. Conclusion and Outlook

The cybersecurity protection practice for wind farm power monitoring systems based on the AuroWan-B1 intelligent networking device provides an efficient and practical solution for wind farm security. Its modular design and strong scalability not only meet current security demands but also lay a solid foundation for future system upgrades and expansion.
