Continuous monitoring of critical systems is crucial to ensuring cyber resilience. This involves constant vigilance over network traffic, system logs, and user activities to identify any deviations from normal patterns. Furthermore, threat intelligence sharing plays a pivotal role in enhancing cybersecurity. Airlines, airports, and relevant government agencies must collaborate to exchange information on emerging threats and attack techniques. This cooperative approach enables the aviation industry to stay ahead of evolving cyber threats by leveraging collective insights and experiences (Brown & Johnson, 2020; ICAO, 2021).
Robust Encryption Protocols:
The implementation of robust encryption protocols is fundamental in safeguarding sensitive data transmitted across aviation networks. Encryption mechanisms, such as Transport Layer Security (TLS), Secure Sockets Layer (SSL), and Advanced Encryption Standard (AES), ensure that data remains confidential and tamper-proof during transmission. By encrypting communications between aircraft, air traffic control centers, and ground systems, the aviation industry can thwart eavesdropping attempts and maintain the integrity of critical data (White, 2019; GAO, 2023).
Collaboration and Cybersecurity Training:
Collaboration between airlines, airports, government agencies, and cybersecurity experts is vital for fostering a holistic approach to cyber resilience. Joint efforts allow for the sharing of best practices, threat intelligence, and lessons learned from cyber incidents.
