Solution Overview
Problem
Current methods for analyzing wireless LAN vulnerabilities are limited in actively detecting attacks and do not effectively integrate with other systems, such as APs and intrusion detection sensors, making it difficult to manage and secure wireless networks.
Innovation Solution
An apparatus with a collection unit, analysis unit, and attack unit that allows a network administrator to collect and analyze wireless packets, perform active vulnerability testing, and control device driver modes for monitoring, illegal access point simulation, and packet forging to detect and counter attacks, while integrating with a server for reporting and countermeasure implementation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional vulnerability analysis systems are used, then basic attack functions can be performed, but the number of attacks is limited and integration with other systems (AP, intrusion detection sensor, server) is insufficient
Solution Approach 1:
The portable terminal is designed to perform multiple functions: collecting wireless packets, analyzing network states, executing various wireless attacks (SSID modification, 802.1x DoS, deauthentication, fake AP), detecting intrusions, and communicating with external systems (AP, intrusion detection sensor, server). This multi-functional design resolves the contradiction by enabling a single device to handle diverse vulnerability analysis tasks without requiring separate specialized systems for each function.
Solution Approach 2:
The portable terminal acts as an intermediary device that bridges the gap between the administrator and the wireless network system. It can connect to APs, communicate with intrusion detection sensors, and exchange data with servers, thereby integrating multiple system components through a single portable device without requiring direct complex interconnections between all systems.
2Reliability
If active vulnerability testing is performed, then vulnerability analysis is improved, but system management complexity increases
Solution Approach 1:
The portable terminal automatically performs vulnerability testing by actively connecting to wireless networks, collecting packets, analyzing network states, and executing attack simulations without requiring manual intervention for each test case. The system self-manages the complexity of coordinating multiple attack functions and system integrations, thereby maintaining high vulnerability detection accuracy while simplifying administrator operations.
Solution Approach 2:
The system dynamically adjusts operating parameters and modes based on the vulnerability analysis requirements. It can switch between different attack modes, modify collection policies, and adapt its behavior based on network conditions, thereby maintaining effective vulnerability testing while managing complexity through automated parameter adjustment rather than manual configuration.
3Adaptability or versatility
If multiple attack functions are implemented, then vulnerability analysis capability is enhanced, but device complexity increases
Solution Approach 1:
The attack system is segmented into distinct functional modules: packet collection unit, network state analysis unit, attack execution unit (with sub-functions forSSID modification, 802.1x DoS, deauthentication, fake AP), intrusion detection unit, and communication units. Each module handles a specific aspect of vulnerability testing independently, allowing the system to offer diverse attack functions while managing complexity through modular architecture where each component has a well-defined role.
