Network Management Device for Automated Firewall Rule Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network management systems lack comprehensive security protection due to the lack of information security background among general network management personnel and the inability of existing intrusion detection systems to effectively block new malicious attacks without human intervention.
Innovation Solution
A network management device and method that automatically collects and analyzes network packet information to determine packet features, generates candidate rules, and applies them to the firewall for unattended network protection, eliminating the need for manual rule formulation and human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual rule formulation is used for network security protection, then network security management can be implemented, but labor costs increase and human intervention is required
Solution Approach 1:
The system performs self-service by automatically collecting network packet information, analyzing packet features, generating firewall rules, and applying them to the firewall without human intervention. The network management device autonomously monitors network traffic, identifies malicious patterns, and updates security rules in real-time, eliminating the need for manual rule formulation and reducing labor costs while maintaining reliable network security protection
Solution Approach 2:
The system performs preliminary action by proactively analyzing network packet information and generating firewall rules before malicious attacks occur. The network management device continuously monitors network traffic, identifies potential security threats through packet feature analysis, and pre-configures protective firewall rules to prevent attacks before they can compromise the network, rather than reacting to incidents after they occur
2Reliability
If blacklist rules are used in intrusion detection systems, then known malicious attacks can be blocked, but new types of malicious attacks cannot be effectively blocked
Solution Approach 1:
The system implements dynamics by transitioning from static blacklist rules to dynamic whitelist firewall rules that adapt to changing network conditions and threat landscapes. The network management device continuously analyzes current network packet information, identifies legitimate traffic patterns through packet feature analysis, and dynamically updates firewall rules to allow legitimate traffic while blocking anomalies. This dynamic approach enables the system to automatically adapt to new attack types without requiring manual rule updates or relying on pre-defined blacklist entries
Solution Approach 2:
The system applies inversion by reversing the traditional blacklist approach and implementing a whitelist-based firewall rule system. Instead of starting with a comprehensive block list and making exceptions, the system starts by identifying and allowing legitimate network traffic patterns through automated analysis of packet features, and automatically blocks anything that deviates from the established whitelist. This inverted approach fundamentally changes how the system handles both known and unknown threats, improving adaptability to new attack types
3Ease of operation
If professional network managers are deployed, then network management capability is improved, but the cost increases and complete understanding of individual network behaviors is still difficult
Solution Approach 1:
The system replaces the mechanical system of human network managers with an automated network management device that performs packet information collection, analysis, and rule generation. The device uses automated algorithms to analyze network packet information, extract packet features, generate firewall rules, and apply them to the firewall without human intervention. This substitution eliminates the need for expensive professional network managers while maintaining or improving network management capability through consistent, error-free automated operations
Solution Approach 2:
The system introduces an intermediary network management device that acts as a mediator between raw network traffic and firewall rule configuration. This intermediary automatically collects network packet information, analyzes packet features to identify legitimate traffic patterns, generates appropriate firewall rules, and applies them to the firewall. By inserting this intelligent intermediary layer, the system simplifies the overall management complexity while improving ease of operation, as the device handles all complex analysis and rule generation tasks autonomously
