드론과 관련된 기술의 발전으로 인하여, 다양한 민간 및 공공 산업에서 활용되는 실정이며, 이에 따라 드론 시장 역시 확대되면서 일반인들도 드론을 접하거나 활용하는 기회가 많아지고 있다. 특히, 일반인들이 접근하기 용이하고 사용하기 쉬운 WiFi 기반의 상용 드론이 생산되면서 수요 역시 증가하는 추세이다. 이와 같이, 드론이 많이 발전하는 긍정적인 측면과는 반대로, 드론에서 발생하는 다양한 취약점으로 인하여 보안 위협이 발생한다. 최근에는 WiFi 기반의 드론들을 대상으로 공개된 도구를 사용하여 DHCP 고갈 공격의 취약점을 분석하는 연구가 진행되었으며, 공격 결과로 실제 드론이 DHCP 고갈 공격으로 인하여 IP 주소를 할당받지 못하는 보안위협이 도출되었다. 하지만, 이 연구는 대표적인 DHCP 공격 도구인 DHCPig와 Yersinia를 활용하였으며, 이 도구들은 무선이 아닌 유선 네트워크를 기반으로 제작되었기 때문에, 드론 환경에 그대로 적용하기에는 한계점이 존재하며, 실제로 발생 가능한 취약점을 검증하지 못하는 한계점도 존재한다. 따라서 본 논문에서는 WiFi 기반 상용 드론을 대상으로 DHCP 고갈 공격의 취약점을 분석하기 위하여, 공개된 도구들의 문제점을 분석하고 개선함으로써, 드론 환경에서의 DHCP 고갈 공격의 가능성을 검증한다. 본 연구 결과는 DHCP를 제공하는 드론 환경의 안전성을 향상하기 위한 지표로 활용될 것으로 사료된다.

Since 1910s, the drones were mainly used for military purposes for reconnaissance and attack targets, but they are now being used in various fields such as disaster prevention, exploration, broadcasting, and surveillance of risk areas. As drones are widely used from military to civilian field, hacking into the drones such as radio disturbance, GPS spoofing, hijacking, etc. targeting drones has begun to occur. Recently, the use of drones in hacking into wireless network has been reported. If the artificial intelligence technology is applied to the drones in the military, hacking into unmanned combat system using drones will occur. In addition, a drone with a hacking program may be able to relay a hacking program to the hacking drone located far away, just as a drone serves as a wireless communication station. And the drones will be equipped with a portable GPS jamming device, which will enable signal disturbance to unmanned combat systems. In this paper, we propose security threats and the anticipated hacking scenarios using the drones on the battlespace to know the seriousness of the security threats by hacking drones and prepare for future cyberspace.

Due to the development of technology and popularization of drone, the so-called "dirty drone" that exploits drones for crimes and terrorism has become a social problem, and it is time to seriously consider the "revenge of drones." Indeed, the cases of threats posed by drones are expanding not only to threats to ground facilities, but also to aviation safety threats, more recently to large-scale events, demonstrations and crimes targeting specific personnel, and terrorism. This research clearly defined the concept of anti-drone when it emerged as a new type of social safety threat as it was abused in crime and terrorism, while response to it was not enough yet. Through this process, it was intended to present an effective anti-drones system. We analyzed the major controversial elements of anti-drone, and defined them as "comprehensive response activities at the legal, institutional and technical levels performed by law enforcement agencies, related technology and industrial entities in a way that prevents, detects, and blocks acts that violate public well-being and order, such as crimes and terrorism caused by the drones." To effectively respond to dirty drones, the authority of law enforcement agencies and the enactment of relevant laws were proposed. In the future, a comprehensive and systematic follow-up study of the anti system should be conducted.

최근 무인항공기는 국내뿐만 아니라 전 세계적으로 활용에 대한 관심이 높아지며 다양한 분야에서 사용되고 있다. 드론은 독립적으로 외부로부터 정보를 수집하는 임무를 수행하거나, 군집을 이루어 데이터를 주고받으며 특정한 임무를 수행하게 된다. 지금까지의 드론에 관한 연구는 신속하고 정확한 임무의 수행에만 초점을 두어왔고, 드론 자체 또는 드론 군집에서 주고받는 데이터의 보안과 안전에 관한 연구는 비교적 소홀히 다루어져 왔다. 따라서 본 연구는 드론 운용에 있어서 구성요소별 보안 취약점을 분석하고 취약점을 해결할 수 있는 대응방안을 설명한다. 특히 드론의 가장 중요한 임무 중 하나인 지상의 목표물 탐색에 있어서 발생할 수 있는 보안위협 요소와 이에 대한 해결방안을 제시한다.

Recently, the technology of drones is developing remarkably. The role of military drones is so great that they can cause serious damage to the enemy's important strategic assets without any damage to our allies in all battlefield environments (land, sea, air). However, the battleship combat management system currently operated by the Korean Navy is vulnerable to defense because there is no customized defense system against drones. As drones continue to develop, they are bound to pose a major threat to navy in the future. This paper proposes a way for the warfare software of naval combat management system sets a combat mode suitable for anti-drone battle, evaluates the threat priority in order to preemptively respond to drone threats and eliminate drone threats through automatic allocation of self-ship-mounted weapons and sensors, and through a test of the improved warfare software in a simulated environment, it was proved that the time to respond to the drone was improved by 62%.

The forces to protect people's life and property against the enemy attack is an organization which is regulated by the constitutional law. In terms of nature, its security is a significant factor to determine success or failure for the war. However, recently the 4th industrial revolution represents the rapid change in the advancement of civilization and technology. It can influence on the environment of military security which can make various changes. Unless taking proper action againsty these changes, it can inflict a vital harm for the organization of forces and its internal security. In this aspect, this study discuss new threats of the military security, above all, the most technical improvements and harms for the drones in terms of security. In addition, the advantages and disadvantages of drones which can influence on the ragions of military command and control, information operations, maneuvers, firepower, operation sustainment supports are analyzed. Moreover, this study set the purpose of developmental security measure for security threats in the aspects of military security.

As drones are widely used, attack attempts using drone vulnerabilities are increasing, and drone security is growing in importance. This paper derives security requirements for reconnaissance drone delivered to government office through threat modeling. Threats are analyzed by the data flow of the drone and collecting possible vulnerabilities. Attack tree is built by analyzed threats. The security requirements were derived from the attack tree and compared with the security requirements suggested by national organizations. Utilizing the security requirements derived from this paper will help in the development and evaluation of secure drones.

The explosive increase in demand for drones poses a major threat to the safety of existing aircraft operations and important national facilities operating in low-altitude airspace. In order to determine the type and degree of safety threats for low-altitude airspace drones, the types and types of threats from drones are evaluated through analysis of AHP(analysis hierarchy process) for aviation workers in each field. The composition of the threat factor hierarchy from drones was designed using a specific operation risk assessment (SORA) technique previously studied by the European Aviation Safety Agency (EASA), an advanced aviation country. Based on this, it will be possible to secure the low-altitude safety operation of existing aircraft by identifying and removing prior hazards between each aircraft operation and mission performance.
