Currently, unmanned aerial vehicles (UAVs) are widely used in civil and military fields. Due to this development, their security also becomes an important aspect. Problems related to the safety of UAVs also arise. Here, not only hacking, but also protection against radio-electronic interference devices are very serious problems. Based on a number of real security incidents, it can be argued that cyber security for UAVs and other unmanned vehicles is of exceptional importance. Various methods and main components neutralization are presented. Examples of real-life security incidents involving UAVs are presented in different years and in several sample countries. UAV system discusses certain methods for preventing and detecting cyber-attacks, anomalous behavior, identifying intrusion attempts and responding in real-time. Cryptography is invaluable in preventing some cyber attacks. Data encryption protects its privacy and prevents interception. This article examines the cybersecurity challenges of UAVs. The integration of artificial intelligence (AI) and machine learning (ML) into wireless network technologies can enable solutions to various security challenges. AI is being researched in a wide range of applications in automated systems and aviation.
