Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cybersecurity systems lack effective methods for predicting and responding to cyberattacks in real-time, as they fail to analyze and utilize patterns in attacker behavior to anticipate and counter potential threats.
Innovation Solution
The implementation of a directed graph model that detects information indicative of a cyberattack, configures this information as input, computes prediction results, classifies nodes, and determines responsive actions based on the prediction results and node classifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cybersecurity systems are used, then system simplicity is maintained, but the ability to predict and respond to cyberattacks in real-time deteriorates
Solution Approach 1:
The system segments the cyberattack prediction process into distinct functional modules: a directed graph model for representing attack patterns, a prediction engine for analyzing attacker behavior sequences, a classification module for categorizing attack types, and a response generation module. This segmentation allows each component to specialize in specific tasks while maintaining overall system reliability for real-time prediction.
Solution Approach 2:
The system performs preliminary actions by pre-configuring the directed graph model with known attack patterns and relationships before actual cyberattacks occur. The model pre-establishes nodes representing potential attack states and edges representing transition probabilities, enabling rapid real-time prediction without requiring complex analysis during the actual attack event.
2Loss of time
If real-time prediction and response capabilities are implemented, then response time is reduced, but system complexity increases
Solution Approach 1:
The directed graph model employs self-service mechanisms by automatically updating transition probabilities based on observed attacker behavior patterns without requiring manual reconfiguration. The system self-adjusts to new attack methodologies by learning from incoming data, reducing the need for complex manual updates while maintaining rapid response capabilities.
Solution Approach 2:
The system utilizes parameter changes in the directed graph model, specifically adjusting transition probabilities between attack states based on learned patterns. By dynamically modifying these probability parameters in response to observed attacker behavior, the system achieves adaptive real-time prediction without adding significant structural complexity.
3Measurement precision
If pattern analysis of attacker behavior is performed, then prediction accuracy is improved, but computational requirements increase
Solution Approach 1:
The system applies partial action by focusing pattern analysis only on the most probable next steps in an attack sequence, rather than analyzing all possible attack paths. The directed graph model prioritizes computation on high-probability transitions, achieving sufficient prediction accuracy while reducing unnecessary computational energy expenditure on low-probability scenarios.
