A review on Unmanned Aerial Vehicle (UAV) threats assessments.

The threat of Unmanned Aerial Vehicle (UAV) attacks abroad is increasing, and it may even happen in Malaysia in the future. Over time, the development of UAV technology has grown rapidly. This proves that UAV attacks are very easy to be carried out by the enemy, and it is difficult to repel such attacks. Therefore, this study is an initial preparation to avoid any potential threats to Malaysia by UAV or drones in the future. The Malaysian force is required to prevent the enemy's UAV from entering Malaysia's airspace. Since its independence, Malaysia has never faced the threat of UAV attacks but with the rising number of UAV attacks internationally, the military must have the ability to defend and destroy the aerial threat source when national security is threatened. The more complex the UAV technology, the greater the threat it may pose. This paper aims to disclose the threats related to physical UAV attacks. This study aims to explore the UAV technologies, their capabilities and usage. This paper also addresses the current UAV threats and UAV threats assessments methodologies. This study establishes a critical literature review in which reflect on the process of analysing and modelling UAVs or drones' threat through attack defence tree in the next research.
