Wi-Fi network data in critical cabin areas (cockpits, offices, conference rooms, etc..) where sensitive information will be shared are vulnerable to remote piracy and hacking attacks.

Numerous cybersecurity efforts including: Enabling Network Encryption Techniques, Hiding SSIDs, Firewalls, VPNs, etc... These solutions can get extremely complicated, slow network traffic, and ultimately fail to protect the network from a stubborn hacker.

Lately (within the last 8 years), an emerging technology that utilizes light waves to communicate data (LiFi or Light Fidelity) has been developed and is slowly getting commercialized. Using a decades old technology used by telecom companies to communicate over fiber optics, LiFi is built from a solid foundation but instead of using cables to transmit the data, it uses the visible light used to light our homes, cars, workspaces, and airplanes.

LiFi is significantly more secure than other wireless technologies because light can be contained in a physical space thus making it virtually impossibly for users in other rooms to hijack LiFi signals. They would simply need to be in the presence of the light to do so.

Also, it should be understood that all existing security protocols for encryption and authentication can be leveraged into LiFi systems to provide even more secure wireless systems.
