Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing and securing IoT devices in networks is challenging due to their ability to connect without permission, vulnerabilities from lack of software updates, and potential for malicious software spread, making network security and device management difficult.
Innovation Solution
A system that detects devices in a network, determines their profiles and risk categories by analyzing data packets, and presents this information through a graphical user interface (GUI), allowing for quick identification and management of devices and potential security threats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If IoT devices are allowed to connect to the network without explicit permission, then network accessibility and ease of device integration are improved, but network security and administrative control deteriorate
Solution Approach 1:
The patent introduces a network administrator interface and automated monitoring system as an intermediary between IoT devices and the network. This mediator tracks device locations, manages permissions, and provides security oversight without preventing easy device connection, thus resolving the contradiction between ease of integration and network security
Solution Approach 2:
The system implements continuous feedback loops where device movements and network activities are monitored and reported to administrators in real-time. This feedback mechanism enables administrators to maintain security control while allowing devices to connect freely, as any unauthorized actions are immediately detected and addressed
2Adaptability or versatility
If IoT devices can be easily relocated without permission, then device mobility and flexibility are improved, but network management complexity and security control worsen
Solution Approach 1:
The patent implements self-service tracking where IoT devices automatically report their locations and status to the network management system without requiring manual registration. This self-reporting mechanism maintains device mobility while simplifying network management, as the system automatically updates device information without administrator intervention
Solution Approach 2:
The manual mechanical process of device registration and tracking is replaced with automated electronic monitoring systems. Sensors and network protocols automatically track device movements and update management databases, eliminating the need for manual tracking and reducing management complexity while preserving device mobility
3Duration of action of stationary object
If software updates are not regularly performed on IoT devices, then device operational continuity is improved, but device vulnerability to network attacks worsens
Solution Approach 1:
The patent implements preliminary action by proactively distributing security updates to IoT devices before vulnerabilities can be exploited. The system monitors for security threats and automatically pushes updates to devices in advance, preventing vulnerabilities from being exploited while maintaining device operational continuity through seamless update processes
Solution Approach 2:
The system applies preliminary anti-action by pre-blocking known attack vectors and vulnerabilities through security updates before malicious actors can exploit them. This proactive security measure counteracts potential harmful factors before they can affect devices, maintaining both operational continuity and security
4Productivity
If malicious software is allowed to spread through the network, then network connectivity and device communication are improved, but overall network security and device safety deteriorate
Solution Approach 1:
The patent extracts and isolates security verification functions from the general network communication process. A separate security layer monitors and filters traffic for malicious software while allowing legitimate communication to proceed uninterrupted. This extraction enables maintaining network communication efficiency while actively preventing malicious software spread
Solution Approach 2:
The system converts the potential harm of widespread device connectivity into a benefit by using the same communication infrastructure to distribute security updates and monitor for threats. The network connectivity that could spread malware is also used to propagate security patches and detection algorithms, turning a vulnerability into a security advantage
Data Source
AI summary
Presenting, at a graphical user interface (GUI), device photos and risk categories associated with devices in a network is described. Data packets communicated in a network are detected. Based on the detected data packets, a set of devices in the network are determined. A set of device photos associated respectively with the set of devices are determined. A GUI concurrently presents the set of device photos to indicate the set of devices detected in the network. The set of devices may be filtered, sorted, and/or grouped based on various criteria. The GUI may present the device photos according to the filtering, sorting, and/or grouping. Additionally or alternatively, risk scores associated respectively with the set of devices are determined. The set of devices are categorized into respective risk categories based on the associated risk scores. A GUI concurrently presents a set of risk categories and information associated with each risk category.
