Identifying and Mitigating Cyber Attacks on Wind Turbine Communication Networks
Wind energy plays a crucial role in the global energy infrastructure. With wind power plants in place, reliable and safe energy could be produced. Wind energy has become a major part of the renewable energy production capacity of the United States over the past few years. There are over 70,800 wind turbines that generate 400 terawatt hours of power in the U.S. In total, wind turbine communication networks produce almost 10% of the country’s electricity. As of last year, 14 states set a record when they managed to cover over 88% of electricity demand through wind energy.
Analyzing Cyber Threats on wind turbine communication networks
Technically, wind turbines depend on communication networks in order to operate as efficiently as possible and transmit operational data to virtual control centers. But these communication networks have become highly vulnerable to rising cyber-attacks that lead to equipment damage, downtime, and revenue loss. This makes identifying and mitigating potential cyber-attacks across wind turbine communication networks very important. The idea is to make sure there’s less operational disruption and potential damage. In the United States, many laboratories now support research and development plans to identify, detect, protect, respond to, mitigate, and recover from cyber-attacks.
In the past few years, there’s been an increase in cyber-attacks on wind turbine network communication. These cyber incidents largely include various ransomware attacks on different wind turbine communication links, maintenance companies, and manufacturers. While a cyber-attack on a single wind turbine poses a minor threat, the cyber attack’s impact on multiple wind turbines is significant. Wind power system operators and owners need to implement the newest cybersecurity practices in order to ensure efficient response and safe recovery from a moderate to severe cyber-attack. In fact, the growth of contemporary wind energy space depends on it.
Recommendations to Identify and Mitigate Cyber Attacks on Wind Turbine Communication Networks
Perform a Risk Assessment
Start by reviewing the potential risks faced by a wind turbine communication network. Focus on identifying network vulnerabilities. It will allow better understanding of the impact of a cyber-attack and help devise a plan to mitigate risks.
Secure the Network
Roll out security measures like intrusion detection, firewalls, network encryption, and prevention systems against cyber-attacks. Also, ensure updating firmware and software with strict access controls.
Conduct Regular Vulnerability Scans
Perform regular vulnerability scans to spot any network weaknesses and address identified network vulnerabilities to prevent cyber attackers from exploitation.
Monitor Network Activity
Keep an eye on the network activity to spot any suspicious activity. Standard network traffic analysis solutions could be used to identify irregular and odd traffic behavior and patterns.
Conduct Regular Training
Conduct training sessions for contractors and employees regularly to better understand who has direct access to the communication network of the wind turbine. The staff should undergo training to embrace the best cybersecurity practices, including social engineering awareness and effective password management.
Develop a Response Plan
Create an incident response plan outlining the necessary steps to be taken in case of a potential cyber attack. This response plan should also contain incident reporting, procedures to follow, isolating the most affected systems, and finally restoring operations.
Back up Critical Data
Regularly back up essential data to ensure its transferability in the event of a cyber attack. Ensure that the backups are stored offsite with advanced encryption.
Today, many startups and companies specialize in identifying and mitigating different types of cyber-attacks on wind turbine communication networks.
