Meanwhile, vehicle charging use cases at airports are still evolving. It is likely that chargers will be deployed both on the ground for shuttles and operations vehicles while also serving aircraft and their support vehicles. These deployments have the potential to greatly increase the number of connection points, adding new cybersecurity priorities for manufacturers and their infrastructure and for airports managing energy demand with site controls.
Electrified aviation requires coordination among a variety of stakeholders, and their data and power connections raise new questions about how to manage cybersecurity. Illustration by Josh Bauer,The NREL report notes that cybersecurity requirements may vary across stakeholder oversight, depending on ownership models and funding sources.
“It’s very interesting to look at the ownership models for airports to understand the authorization processes from a cybersecurity requirements perspective,” said Anuj Sanghvi, a project lead at NREL. “For asset owners and responsible entities, it will be valuable to have tools that provide insight into authorization processes. There is much work to be done beyond the initial guidance thus far.”
The report addresses this multistakeholder situation by recommending a set of security principles based on existing standards and guidelines. For starters, network segmentation can effectively isolate assets from one another, and firewalls can limit data risks from untrusted network traffic. Technologies like
can stand between assets as a “bump in the wire,” adding authentication via traditional mechanisms like Transport Layer Security, and other solutions such as intrusion detection systems can be scaled to provide visibility and threat monitoring throughout the network.
