Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network security systems fail to provide a dynamic, on-demand firewall solution that caters to the diverse and localized security needs of various devices in next-generation cellular networks, such as 5G and 6G, which host a multitude of IoT devices, vehicles, and other equipment, lacking a unified security posture.
Innovation Solution
An Intelligent Dynamic Firewall (IDFW) is deployed autonomously at the network edge, utilizing a backend orchestrator to manage local modules that provide tailored firewall services based on subscriber profiles, detecting and responding to security threats in a distributed manner, adapting to device activities and geographical areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized firewall system is used to provide security for all devices in the network, then comprehensive security coverage is achieved, but system complexity and response time increase due to the large number of devices and nodes
Solution Approach 1:
The patent segments the centralized firewall system into multiple distributed local firewall modules deployed at network edges and access points. Each local module independently handles security for devices in its geographical area, dividing the large-scale security problem into smaller, manageable segments that reduce overall system complexity while maintaining comprehensive coverage.
Solution Approach 2:
The patent introduces a spatial dimension to firewall deployment by placing local firewall modules at various geographical locations throughout the network infrastructure. This transforms the traditional single-point centralized security model into a multi-dimensional distributed architecture, where security is provided both centrally and locally across different spatial levels.
2Reliability
If a centralized firewall system monitors all communication activity across the entire network, then complete threat detection is achieved, but network resources become overburdened and response time increases
Solution Approach 1:
The patent segments the network monitoring function into multiple local firewall modules that each monitor only the communication activity within their specific geographical areas. This segmentation distributes the monitoring workload across multiple independent units, preventing any single system from becoming overburdened while maintaining complete network-wide threat detection capability.
Solution Approach 2:
The patent implements local quality by enabling each firewall module to independently detect and respond to threats within its local area without requiring centralized processing of all network traffic. This localized approach optimizes resource utilization by processing security data where it is generated, reducing network bandwidth consumption and improving response time.
3Ease of operation
If static firewall rules are implemented to protect devices, then security policy enforcement is simple, but the system cannot adapt to dynamic security threats and changing device activities
Solution Approach 1:
The patent implements dynamic firewall rules at each local module that can automatically adapt to changing security conditions and device activities. The system continuously monitors network traffic patterns and threat levels, dynamically adjusting security policies in real-time without requiring manual reconfiguration, thus maintaining both operational simplicity and high adaptability.
Solution Approach 2:
The patent incorporates feedback mechanisms where each local firewall module continuously monitors its environment, detects security threats, and automatically adjusts its filtering rules based on the detected conditions. This closed-loop system provides ongoing adaptability to new threats while maintaining simple operation through automated decision-making algorithms.
4Speed
If distributed local firewall modules are deployed throughout the network, then response time and resource efficiency improve, but system complexity increases due to coordination requirements
Solution Approach 1:
The patent merges the functionality of multiple distributed local firewall modules with a centralized coordinator through standardized communication protocols. The local modules operate independently for rapid local response while periodically synchronizing with the central coordinator, combining the speed benefits of distribution with the simplicity of centralized management.
Solution Approach 2:
The patent implements universal communication protocols and standardized interfaces that enable different local firewall modules to coordinate efficiently despite their distributed nature. This multi-functional approach allows the system to handle both autonomous local threat response and coordinated network-wide security operations through a unified framework.
