1. What are the basics of smart grid cybersecurity?
With the innovations and advancements across the globe, traditional grids are being transformed into smart grids. However, while these smart grids offer a wide array of benefits, they are highly vulnerable to cyberattacks. Therefore, it is important to secure smart grid physical systems against cyberattacks and maintain cybersecurity for power grids. Furthermore, cybersecurity should not be interpreted as a retrofit. Rather, it should be considered a part of smart grid development. It is important to protect smart grids against potential terrorist threats, espionage threats, and vulnerabilities caused by natural disasters, equipment failures, and user errors.
2. Why cybersecurity is a concern in smart grids?
It is important to understand that IoT-based smart grid systems have critical infrastructure and include complex devices as well as architecture. Cybersecurity is a major concern in such critical systems because the confidentiality, availability, or integrity of communication systems is broken down due to cyberattacks, it can disrupt public order and national security and cause large-scale economic damage or loss of life. Therefore, it is imperative to maintain the electric grids' cybersecurity.
3. What is the importance of smart grid cybersecurity?
Smart grid systems help utilities in conserving energy, reducing costs, increasing transparency and reliability, and making processes highly efficient. However, the increased use of IT-based electric power systems increases cybersecurity vulnerabilities, leading to the increased need to adopt resilient cybersecurity solutions. Therefore, it is important for utilities to adopt smart grid cybersecurity solutions for data management and privacy concerns, layered security approaches, strategic issues, vulnerable areas, threat profiling, and maintaining electric grid cybersecurity.
4. What are the cybersecurity challenges and solutions in the smart grid?
Smart grid systems’ characteristics such as delay constraints, heterogeneity, scalability, bandwidth, and others make it quite challenging to deploy comprehensive and uniform security approaches across all network segments. As an IoT-based smart grid consists of millions of nodes, it has a large attack surface for an IoT-related cyberattack, which might have devastating effects on the reliability of the smart grid system.
