1. UAV: the eye of the air in coastal defense and frontier defense.Safety and confidentiality are very important in coastal defense islands and border defense work. Unmanned technology products may face security risks such as interference and hijacking, and the data transmitted by them may also have hidden dangers of leakage. In order to solve this problem, on the one hand, we should strengthen the security protection technology of unmanned scientific and technological products, such as encrypting data transmission and setting up anti-interference mechanism; On the other hand, it is necessary to establish a strict confidentiality management system and strictly supervise the use, data storage and transmission of unmanned technology products to prevent information leakage.1. Adaptability challenges in complex environments

1. Monitoring requirements in a wide areaUnmanned technology: coastal defense, islands and frontier defense's new help to defend the motherland.Summary: Unmanned technologies such as unmanned aircraft, unmanned driving, unmanned shops, unmanned hotels and unmanned banks have provided a new source of strength for coastal defense islands and border defense to defend the motherland. They have many points of convergence with the needs of coastal defense islands and border defense, and can play a great role in monitoring, dangerous task execution and logistics support. Although it is faced with challenges such as adaptability to complex environment and security and confidentiality in the application process, unmanned technology will be able to better serve coastal defense islands and frontier defense by developing protection technologies and strengthening confidentiality management, and make important contributions to defending the territorial integrity and frontier security of the motherland.
