RF Emitter Detector for Enterprise Network Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Enterprises face challenges in gaining network visibility and control outside their private networks, particularly with smart devices from closed ecosystems, where existing solutions like Enterprise Mobility Management (EMM) may not provide trustworthy threat detection and timely mitigation.
Innovation Solution
A system comprising a user equipment sniffer (UES) or RF sniffer that detects in-range RF emitters, geolocates, tracks, and maps them, using data from multiple sniffers and external sources to identify rogue base stations and transmit information to the cloud for mapping, while also providing RF shielding to prevent unauthorized network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If Enterprise Mobility Management (EMM) software is installed on smart devices to gain network visibility, then network visibility is improved, but the reliability of threat detection deteriorates because data gathered by EMM may not be trustworthy
Solution Approach 1:
The patent introduces an RF sniffer as an intermediary device that independently monitors RF emissions from smart devices. Instead of relying on data from EMM software installed on potentially compromised devices, the RF sniffer passively captures RF signals and analyzes them for threat detection, providing an external and trustworthy verification mechanism.
Solution Approach 2:
The patent replaces the software-based EMM threat detection mechanism with a hardware-based RF signal analysis system. By substituting the mechanical/software approach (EMM software on devices) with a physical RF monitoring approach, the system achieves more reliable and trustworthy threat detection independent of device ecosystem limitations.
2Reliability
If enterprises rely on EMM software for threat detection, then some level of monitoring is achieved, but the speed of threat mitigation deteriorates because smart devices lack a switch to quickly cease operation
Solution Approach 1:
The RF sniffer acts as an external intermediary that can independently detect threats and trigger mitigation actions. When a threat is detected through RF analysis, the system can immediately activate RF shielding or alert users, providing rapid response without waiting for device software responses or user awareness.
Solution Approach 2:
The system implements preliminary protective measures by having RF shielding capability ready to activate immediately upon threat detection. This preliminary anti-action allows the system to preemptively block RF communications from compromised devices, stopping threat propagation before it can spread further across the network.
3Loss of information
If enterprises install EMM software on smart devices from closed ecosystems, then some network visibility is gained, but the measurement precision of threat detection deteriorates due to lack of visibility into device activities and mechanisms
Solution Approach 1:
The patent replaces software-based monitoring attempts within closed ecosystems with hardware-based RF signal interception. By listening to RF emissions externally, the system bypasses ecosystem restrictions and gains precise visibility into device communications, including encrypted traffic patterns, without needing internal device access or trust.
Solution Approach 2:
The RF sniffer serves as an external intermediary that observes device communications passively through RF signals. This external positioning allows it to monitor all device activities including those from closed ecosystems without being constrained by manufacturer restrictions, providing comprehensive and precise threat detection capability.
