Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in effectively detecting and mitigating malicious network threats as malicious actors continually evolve and develop new forms of malware, necessitating improved methods for threat identification and mitigation.
Innovation Solution
A system and method that analyze network data from various sources to generate a risk score for predicting malicious activities, identify the origin and location of threats, and mitigate them by updating a reputation database and relaying information to third parties, including client firewalls and defensive systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional malware detection mechanisms are used, then some malicious threats can be detected, but new and evolving malware can evade detection
Solution Approach 1:
The system performs preliminary actions by collecting and analyzing network traffic data before threats fully manifest, building reputation profiles and baseline behaviors in advance. This allows the system to detect new malware variants by comparing them against pre-established patterns and reputations, rather than waiting for signatures to be created.
Solution Approach 2:
The system implements dynamic adaptation by continuously learning from new network traffic data and updating its detection models in real-time. The reputation system dynamically adjusts threat assessments based on evolving behaviors, allowing the system to maintain high reliability while adapting to new malware variants that continuously emerge.
2Measurement precision
If comprehensive network data analysis is performed to improve threat detection, then detection accuracy improves, but system complexity increases
Solution Approach 1:
The system segments the complex threat detection task into distinct functional modules: data collection from multiple sources, feature extraction and weighting, reputation scoring, and mitigation decision-making. Each module handles a specific aspect of the analysis, making the overall system more manageable and maintainable while achieving comprehensive detection accuracy.
Solution Approach 2:
The system introduces intermediary components such as reputation databases and feature weighting layers that mediate between raw network data and final threat decisions. These intermediaries process and structure the data flow, reducing complexity by providing standardized interfaces between different system components while enabling precise threat measurement.
3Speed
If real-time network traffic monitoring is implemented to detect threats quickly, then response time improves, but resource consumption increases
Solution Approach 1:
The system applies partial action by focusing computational resources on analyzing only the most relevant features of network traffic data using weighted features. Rather than processing every aspect of all traffic equally, the system identifies and analyzes key indicators of compromise, achieving fast detection with reduced resource consumption by concentrating effort on the most informative signals.
Data Source
AI summary
Implementations of the present disclosure involve a system and/or method for identifying and mitigating malicious network threats.
