Cybersecurity System for Roaming Network Threat Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G wireless networks introduce new cybersecurity threats due to increased data volumes and vulnerabilities, with conventional security techniques being cost-prohibitive and resource-intensive to address the asymmetry of security information between interconnected networks, particularly for roaming devices.
Innovation Solution
A cybersecurity system that collects and standardizes security data into a vulnerability-risk-threat (VRT) model, enabling the sharing of security information among operators to mitigate cyberattacks by characterizing network traffic and recommending actions such as blocking or redirecting network traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional security techniques are deployed across diverse networks and devices, then security coverage is improved, but cost and resource consumption become prohibitive
Solution Approach 1:
The patent introduces a cybersecurity system as an intermediary that mediates security information exchange between interconnected networks. This centralizes security functions, allowing networks to share threat intelligence and security data without each network needing to independently deploy comprehensive security resources across all devices.
Solution Approach 2:
The cybersecurity system provides universal security services that can be applied across multiple networks and device types. By creating a multi-functional platform that handles various security tasks (threat detection, data sharing, risk assessment), the system eliminates the need for separate specialized security solutions for each network.
2Loss of information
If security resources are widely distributed across networks, then security monitoring capability is improved, but information asymmetry between networks persists
Solution Approach 1:
The patent merges security information from multiple networks into a centralized cybersecurity system. By combining threat intelligence, security data, and monitoring capabilities across interconnected networks, the system eliminates information asymmetry while maintaining enhanced monitoring capability through aggregated data.
Solution Approach 2:
The cybersecurity system implements feedback mechanisms where security information is continuously exchanged between networks and the central system. This creates a closed-loop information flow that ensures all networks have access to current threat intelligence and security状况, reducing information asymmetry while improving overall monitoring capability.
3Device complexity
If targeted safeguards are implemented, then resource efficiency is improved, but security coverage against diverse threats may be insufficient
Solution Approach 1:
The cybersecurity system dynamically changes security parameters based on threat levels, network conditions, and risk assessments. By adjusting security measures according to actual needs rather than applying uniform protection, the system achieves resource efficiency while maintaining adequate coverage against diverse threats through adaptive parameter modification.
Data Source
AI summary
An inbound roaming system processes a connection of a wireless device to roam on a visited wireless network. The system queries a network resource that stores security data of a home wireless network for the wireless device. In response to the query, the system receives an indication of a security parameter that relates the security data to a potential cyberattack enabled by the wireless device roaming on the visited wireless network. The system then performs, based on the security parameter, an action to mitigate the potential cyberattack.
