Now-a-days, drones become increasingly popular for various applications, including surveillance, delivery, and inspection. However, they are vulnerable to attacks, especially GPS spoofing and jamming, which can disrupt their GPS signals and cause them to crash. In response, academic research has proposed various methods for detecting and mitigating these attacks, such as using multiple GPS receivers, inertial navigation systems, and statistical analysis of GPS signals. Beyond GPS attacks, cybersecurity for drones is a broader issue that includes denial-of-service attacks, malware attacks, and physical attacks on the drone itself. These attacks can compromise the confidentiality, integrity, and availability of drone systems, posing significant risks to operators and the public. To address these threats, ongoing research and development of countermeasures are needed, as new and more sophisticated attacks may continue to emerge as technology advances. The development of effective countermeasures requires collaboration among academia, industry, and government agencies to ensure that drone systems are robust, resilient, and secure against cyber and physical attacks. Additionally, regulations and standards must be established to ensure the safe and secure operation of drones, including cybersecurity requirements that mandate secure communication, authentication, and encryption protocols. In summary, the increasing use of drones in various applications highlights the importance of addressing the cybersecurity challenges that arise from their use. The development of effective countermeasures to GPS spoofing, jamming, and other attacks is critical to ensuring the safety and security of drone systems, operators, and the public. Ongoing research and collaboration among stakeholders are essential to achieving this goal and to mitigating the risks associated with drone operations.
