The modern internet landscape continues to expand with the widespread adoption of diverse endpoint devices, including smartphones, connected vehicles, and Internet of Things (IoT) devices. Alongside this evolution, Distributed Denial of Service (DDoS) attacks—traditionally aimed at service providers and large-scale infrastructures—have recently shifted toward smaller-scale targets such as individual users and content creators. This study examines recent cases of bandwidth exhaustion–type DDoS attacks targeting individual users and analyzes emerging attack patterns in personal network environments. Based on this analysis, we propose a lightweight packet-based detection and mitigation methodology suitable for environments where deploying enterprise-grade security appliances is impractical. Furthermore, we present the design and implementation approach for a prototype security device tailored for personal-scale DDoS protection, demonstrating the feasibility of applying the proposed method in real-world scenarios. □ keywords Distributed Denial of Service (DDoS), Bandwidth Exhaustion Attack, Personal Network Security, Content Creators, Prototype Defense System
