Solution Overview
Problem
IoT devices lack effective security measures due to limited computing capabilities and resource constraints, making them vulnerable to malware and cyber threats, which can lead to privacy violations and critical infrastructure disruptions.
Innovation Solution
A method and system for enhancing IoT device security by installing security components on these devices through a gateway, which intercepts interactions, analyzes traffic, and identifies necessary security components based on device and user categories, thereby reducing the risk of cyber threats and infections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security components are installed on IoT devices, then security protection is improved, but device complexity and resource requirements increase
Solution Approach 1:
The patent introduces a gateway as an intermediary device between the IoT device and the security service. The gateway performs security analysis, threat detection, and security component delivery without requiring these complex functions to be executed on the IoT device itself. This mediator approach allows security protection to be improved while keeping the IoT device simple and resource-constrained.
Solution Approach 2:
The security system is segmented into separate functional components: the IoT device for data collection, the gateway for security analysis and threat detection, and the security service for component delivery. This segmentation allows each component to be optimized independently, with the gateway handling the computational burden of security analysis while the IoT device maintains its simplicity.
2Difficulty of detecting and measuring
If comprehensive security analysis is performed on device interactions, then threat detection capability is improved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary security analysis and threat detection at the gateway level before security components need to be activated on the IoT device. By pre-analyzing device interactions, classifying threats, and preparing security responses in advance, the system reduces real-time processing requirements and enables faster response to security incidents.
Solution Approach 2:
The system implements a feedback mechanism where security analysis results are continuously monitored and used to adjust security component delivery and activation. This feedback loop allows the system to learn from past security incidents and optimize future detection and response times, reducing overall processing time through adaptive security measures.

AI summary
Disclosed herein are systems and methods for providing security to an Internet of Things (IoT) device. An exemplary method comprises, obtaining, by an interceptor located on at least one gateway or the device, information about an interaction of the device with at least one of: other devices, service, and server; by an analysis tool located on the gateway: determining at least one category of the device and at least one category of a user of the device by interacting with a security service based on information received about the interaction of the device; receiving data from the security service, and identifying the security component to be installed on the device based on the data received from the security service, the category of the device and the category of a user of the device; and installing on the device, by the interceptor, the security component identified by the analysis tool.
