Unmanned aerial vehicle (UAV)-enabled wireless systems are expected for widespread communication applications in future-generation networks because of their flexible deployment and on-demand mobility. This paper considers a UAV-supported system on a generalized environment α - κ - μ with arbitrary fading parameters. In an environment, such a system is vulnerable to security threats due to its broadcast nature and the dominant channel of visibility conditions occurring within the system. Thus, the physical layer security of the system is investigated against key secret performance metrics including secure outage probability (SOP), intercept probability, strictly positive secrecy capacity (SPSC), and ergodic secrecy capacity (ESC). In this paper, the derivatives of closed-form expressions of SOP, SPSC and ESC are determined, and the security performance of the system is compared in different fading environments.
