Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home networks face increasing complexity and security threats as more devices connect, requiring easier-to-use and more effective administration and security tools to manage and protect these networks.
Innovation Solution
A Home Security Gateway (HSG) device is introduced, which provides comprehensive security and administration tools, including threat reputation management, device profiling, wireless intrusion prevention, and malware inspection, supported by a consumer device and optionally a security operations center for remote management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If more devices are connected to the home network, then network functionality and device availability are improved, but security threats and network complexity increase
Solution Approach 1:
The patent introduces a gateway device as an intermediary between the home network and external networks. This gateway monitors incoming connection requests, profiles devices using passive monitoring and active fingerprinting techniques, and controls access based on security policies. The gateway acts as a mediator that allows legitimate devices to connect while blocking malicious ones, thus enabling device connectivity while mitigating security threats.
Solution Approach 2:
The system performs preliminary device profiling and authentication before allowing devices to access the home network. The gateway captures packets during the connection establishment phase, profiles the connecting device, and determines security policies before the device gains full network access. This preliminary action prevents malicious devices from compromising the network while still allowing legitimate devices to connect.
2Adaptability or versatility
If more devices are connected to the home network, then network functionality is improved, but network administration complexity increases
Solution Approach 1:
The gateway device automatically performs device profiling, security assessment, and access control policy enforcement without requiring manual intervention from network administrators. The system self-manages the complexity of monitoring and controlling multiple devices by automatically capturing packets, profiling devices, and enforcing security policies, thus simplifying network administration while supporting device connectivity.
Solution Approach 2:
The gateway device provides multiple functions including device profiling, security monitoring, access control, and network management all through a single device. This multi-functional approach consolidates what would otherwise require multiple separate tools and manual processes, making network administration simpler while supporting diverse device connectivity.
3Reliability
If traditional security tools are used, then basic security protection is provided, but ease of use for non-professional administrators deteriorates
Solution Approach 1:
The gateway automatically performs security assessments, device profiling, and policy enforcement without requiring user expertise. Non-professional administrators simply need to connect devices to the network, and the gateway handles all security complexities automatically, maintaining high security protection while achieving ease of operation.
Solution Approach 2:
The system dynamically adjusts security parameters and policies based on device profiles and threat assessments rather than requiring manual configuration. The gateway automatically modifies security settings, access controls, and monitoring parameters based on the connecting device's characteristics, providing enterprise-grade security adaptation without requiring administrator expertise.
