Infected System Tracking via Heuristic Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current reactive methods for detecting and containing malware are insufficient, as they rely on signature-based identification and are time and labor intensive, allowing malware to cause significant damage before detection and reaction.
Innovation Solution
Implementing a dynamic control system using heuristic analysis to identify and isolate infected systems through Infected System Tracking, which includes four operations: infected system and port identification, site identification, creation of a blocking access control list, and propagation of the blocking ACL, to reduce the spread of malware.

Engineering Contradiction Analysis
1Measurement precision
If signature-based identification methods are used to detect malware, then detection accuracy for known malware is improved, but response time deteriorates and damage occurs before detection
Solution Approach 1:
The system performs preliminary actions by proactively identifying potential malware infections before they can cause significant damage. The heuristic analysis continuously monitors network traffic and system behavior, detecting anomalies that indicate malware presence before traditional signature-based methods would identify the threat, thus reducing the time loss between infection and detection.
Solution Approach 2:
The system rushes through the detection process by implementing real-time monitoring and automated response mechanisms. When malware is detected through heuristic analysis, the system immediately initiates containment procedures such as isolating infected systems or blocking malicious network traffic, skipping the delays associated with traditional reactive signature-based detection and manual response processes.
2Device complexity
If reactive detection methods are used, then implementation simplicity is improved, but network security deteriorates due to delayed response
Solution Approach 1:
The system implements self-service capabilities through automated heuristic analysis and response mechanisms. The monitoring system automatically detects potential malware infections, analyzes network traffic patterns, identifies infected systems, and executes containment procedures without requiring constant human intervention. This automation maintains simplicity while significantly improving network security through faster, more reliable detection and response.
3Ease of operation
If traditional malware identification methods are used, then ease of operation is improved, but productivity deteriorates due to time-consuming manual processes
Solution Approach 1:
The system implements continuous feedback loops where network traffic data is constantly collected, analyzed, and used to update detection models. The automated response mechanisms provide immediate feedback by isolating infected systems and blocking malicious traffic in real-time. This feedback-driven approach maintains ease of operation through automation while dramatically improving productivity by eliminating manual analysis and response processes.
