Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks lack effective methods to generate device-specific security rules tailored to individual network devices, particularly for defending against DDoS and botnet attacks, while minimizing resource consumption and ensuring compatibility with device capabilities.
Innovation Solution
A system generates device-specific security rules based on network device information, security policies, and attack samples, using a programming language, and adjusts these rules based on feedback to optimize resource usage and efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If generic security rules are applied to network devices, then security coverage is provided, but device-specific optimization and resource efficiency are lost
Solution Approach 1:
The patent applies local quality by generating device-specific security rules tailored to individual network devices based on their unique capabilities, configuration, and telemetry data. Instead of using uniform generic rules, the system customizes security rules for each device to optimize both security effectiveness and resource consumption, directly resolving the contradiction between security coverage and resource efficiency.
Solution Approach 2:
The system dynamically adjusts security rule parameters based on device-specific characteristics including hardware capabilities, operating system versions, capacity metrics, and runtime telemetry. This parameter adaptation enables the same security framework to efficiently deploy optimized rules across diverse device types while maintaining effective security coverage.
2Productivity
If security rules are customized for each network device, then resource consumption is optimized, but system complexity increases
Solution Approach 1:
The patent segments the security rule generation process into distinct modular components: receiving security policies, collecting device information, generating device-specific rules, compiling rules into executable formats, and deploying rules to devices. This segmentation allows each component to be independently developed, tested, and maintained, reducing overall system complexity while enabling customized security rules for each device.
Solution Approach 2:
The system introduces an intermediary rule generation and compilation layer that translates high-level security policies into device-specific executable rules. This intermediary layer abstracts the complexity of device diversity from the security policy definition layer, allowing simple policy inputs to produce optimized device-specific rules without exposing the underlying complexity to users or administrators.
3Adaptability or versatility
If security rules are generated based on device capabilities, then compatibility is ensured, but rule customization complexity increases
Solution Approach 1:
The patent performs preliminary actions by collecting and analyzing device information, capabilities, and configuration data before generating security rules. The system proactively gathers telemetry data, hardware specifications, and software versions in advance, enabling the rule generation process to automatically adapt to device characteristics without increasing operational complexity during rule deployment.
Solution Approach 2:
The system creates a universal security rule generation framework that handles multiple device types, vendors, and platforms through a single unified process. The framework universally accepts security policies and device information inputs, then generates compatible rules for diverse devices including routers, switches, and other network equipment, ensuring broad adaptability without requiring device-specific custom implementation logic.
