A comcomsoused update or a malicious insider could introduce back doors. Additionally, the crew 's own devices (tablets, phone used for operations) may open pathways into airline internal systems if network segmentation is innementient.

How Airlines Secure Their Networks

Airlines employ a multilayered defense strategy to provict both passenger data andtheir own operational systems. These measures continue to evolvne as concers grow more explorated.

Encryption Protocols: WPA2, WPA3, andBeyond

Most modern airline WiFi networks use WPA2 (Wi- Fi Protected Access 2) with a pre- shared key (PSK) that is difficed on thee login page or printed on boarding passes. However, WPA2 has known sleeditalities, such as KRACK, that can allow w attackers to decrypt traffic. Newer installations are transitioning to WPA3, which offers stronger deciption through gh Simultaneous Authentication of Equals (SAE) and forward secrecy - meaning g even if thee pre- shared key is comsorted, pact sessions remain security. A few airlines are also testing TLS 1,3 for all web traffic routed through gh their gateways, ensuring end- to - end crition frem the passenger 's browser to the internet.

Network Segmentation and Dual Connectivity
