Threats and Countermeasures In Iot and 5g Environments. Designing A Vulnerability Detection System

It is well known that with the rapid growth of Internet of Things (IoT) and 5G technologies, security challenges also arise in modern networks whether they are due to the increasing number of vulnerable devices or limited user awareness. This paper showcases the design and implementation of a user-focused Vulnerability Detection System (VDS), developed as a Windows desktop application using the .NET MAUI framework and structured according to the MVVM (Model-View-ViewModel) design pattern. The system enables users to scan local networks, identify connected devices, detect vulnerabilities, monitor DNS queries, and perform ARP spoofing and packet inspection, all through a modern graphical interface. Designed for accessibility and modularity, the VDS integrates external APIs to enrich device data and employs a layered architecture to ensure scalability and maintainability. The initial development focused on building a functional prototype with core features.
