With the digitization of grids, cybersecurity has become a critical concern. Startups are developing:

• Threat detection and prevention systems
• Secure communication protocols
• Data privacy solutions

The global smart grid cyber security market was forecast at 6.4 billion U.S. dollars in 2022. It was expected to grow at a Compound-Annual Growth Rate (CAGR) of approximately 11.4 percent until 2029, reaching 13.69 billion U.S. dollars that year. [18]

The grids' virtual and physical weak spots, or points in software or hardware that are susceptible to cyber criminals, grew to a range of 23,000 to 24,000 last year from 21,000 to 22,000 by the end of 2022, executives with the energy regulator said. [20]

The susceptibility of the U.S. power grid to cyberattacks is increasing due to several factors [21]:

1. Industrial Control Systems: The adoption of more affordable and commonly available devices that employ standard networking protocols within industrial control systems has expanded the potential targets for cyber intrusions, enlarging the attack surface of the grid's infrastructure.
2. Consumer Internet of Things (IoT) Devices: There's a risk that cybercriminals could hijack numerous high-wattage consumer IoT devices, such as air conditioners and heaters. These devices could be orchestrated into a botnet to conduct synchronized attacks that disrupt power distribution by manipulating electricity demand.
3. Global Positioning System (GPS): The grid's reliance on GPS for accurate timing to manage and synchronize its generation, transmission, and distribution operations also presents a vulnerability. A disruption or manipulation of GPS signals could impair critical grid functions.

Overall, these vulnerabilities underscore the pressing need for the grid to enhance its cybersecurity measures to counter the growing risks and ensure reliability and safety.
