Access Point Mode Switching for Rogue Device Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring rogue access points in wireless networks are inefficient and costly, as they require physical patrols or dedicated devices that can only cover limited areas, making it difficult to consistently detect and manage anomalous devices without disrupting network access.
Innovation Solution
An access point that switches between access point mode and surveillance mode, allowing it to temporarily hand off connected stations and scan for anomalous devices, maintaining network connectivity and enabling comprehensive monitoring without physical effort or excessive resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical walk-throughs are used to check for rogue access points, then monitoring can be performed, but it is ineffective for consistent monitoring and requires continuous physical effort
Solution Approach 1:
The access point automatically performs surveillance functions without requiring physical intervention. The system self-monitors by switching between access point mode and surveillance mode, detecting rogue devices autonomously and maintaining continuous monitoring capability without human effort.
Solution Approach 2:
The access point dynamically switches between two operational modes: access point mode for providing network service and surveillance mode for detecting rogue devices. This dynamic mode switching enables the system to adapt its function based on operational needs, achieving both service provision and security monitoring.
2Area of stationary object
If dedicated monitoring devices are deployed to constantly monitor for rogue access points, then monitoring coverage can be improved, but the cost increases significantly and each device can only cover a limited area
Solution Approach 1:
The access point serves multiple functions: it provides network access to legitimate devices and simultaneously performs surveillance for rogue devices. This multi-functionality eliminates the need for separate dedicated monitoring devices, reducing the total number of devices required while expanding effective monitoring coverage across the entire network area.
Solution Approach 2:
The patent combines the access point function and the surveillance function into a single integrated device. By merging these previously separate functions, the system achieves comprehensive monitoring coverage without requiring multiple dedicated monitoring devices, thereby reducing device quantity and deployment cost.
3Reliability
If access points continuously provide network access, then connectivity is maintained, but the ability to detect rogue devices is compromised
Solution Approach 1:
The access point periodically switches between access point mode and surveillance mode in a cyclic manner. During surveillance mode, it detects rogue devices; during access point mode, it provides network connectivity. This periodic switching ensures both functions are performed effectively without compromising either connectivity or detection capability.
Solution Approach 2:
The access point performs surveillance actions at predetermined intervals or under specific conditions (such as when traffic patterns suggest potential threats). This preliminary and conditional surveillance approach ensures rogue devices are detected proactively while maintaining continuous network access, balancing both requirements.
Data Source
AI summary
An access point switches between an access point mode and a surveillance mode. In the access point mode, the access point provides network access for end stations using a BSSID (Basic Service Set Identifier) while in the access point mode. In surveillance mode, the access point scans one or more channels of the wireless network to identify one or more anomalous devices.
