Distributed Anomaly Detection for Zero-Day Malware Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for identifying the footprint of malicious software, especially zero-day attacks, are inefficient and require human expertise, often resulting in false positives and inability to accurately detect and remove offending software.
Innovation Solution
A system that detects anomalies in a network, identifies associated features, updates them, and communicates this information across nodes to correlate and determine the presence of malicious software, allowing for automatic identification and removal of undesirable features without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If semi-automated methods like Strider or Triumfant are used to identify malicious software footprint, then more data is provided to specialists, but human expertise is still required and false positives increase
Solution Approach 1:
The system enables self-service by implementing automated anomaly detection and footprint identification that operates without human intervention. The distributed network of computing nodes automatically correlates features and identifies malicious software, eliminating the need for human specialists to manually analyze attack footprints while maintaining high accuracy and reducing false positives through collective network intelligence.
2Measurement precision
If human specialists manually identify malicious software features, then accurate detection is achieved, but the process is painstaking and time-consuming
Solution Approach 1:
The system replaces the mechanical process of manual human analysis with automated computational mechanisms. Distributed computing nodes automatically detect anomalies, identify features, and correlate data to identify malicious software footprints, achieving both high accuracy and rapid processing without the time-consuming manual intervention previously required by human specialists.
Solution Approach 2:
The system segments the identification process into distributed tasks performed by multiple independent computing nodes. Each node autonomously detects anomalies and identifies features locally, then contributes findings to the collective network analysis, enabling parallel processing that dramatically reduces identification time while maintaining detection accuracy through distributed intelligence.
3Extent of automation
If knowledge bases of known attacks are used for anomaly detection, then automated response is enabled, but zero-day attacks cannot be detected
Solution Approach 1:
The system implements dynamic adaptability by using distributed anomaly detection that learns from collective network data rather than relying on static knowledge bases. The distributed network continuously adapts to new attack patterns by correlating features across multiple nodes, enabling automatic detection of zero-day attacks while maintaining automated response capabilities through real-time collective intelligence.

AI summary
One embodiment of the present invention provides a system for identifying undesirable features in a network of computers. During operation, the system detects an anomaly associated with a node in the network. Next, the system identifies one or more features which are associated with the anomaly. The system then updates the identified features. Next, the system communicates the information corresponding to updated features to at least one other node in the network. The system then receives information indicating a correlation between the updated features and the anomaly from at least one other node in the network. Next, the system correlates the updated features with the anomaly based on the received information. The system subsequently produces a result which indicates a correlation between the updated features and the anomaly.
