Solution Overview

Problem

Existing analysis engines, such as Large Language Models (LLMs), face limitations in processing large amounts of contextual data due to fixed context windows, leading to inefficiencies and computational resource demands, which hinder effective analysis of anomalous security data in cybersecurity applications.

Innovation Solution

Implementing a filtering mechanism to curate a selection of relevant non-anomalous security data items that correspond to the anomalous data, providing sufficient context within the context window of the analysis engine, thereby reducing data overhead and enhancing computational efficiency while maintaining accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If large amounts of contextual security data items are provided to the analysis engine, then the accuracy of analyzing anomalous data items is improved, but the computational resources required and processing time increase significantly

Engineering Contradiction:
Improveaccuracy of analysisVSAvoidcomputational resources
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The filtering mechanism extracts only the most relevant non-anomalous security data items from the large dataset, removing unnecessary contextual data before presenting it to the analysis engine. This extraction process maintains the essential context needed for accurate anomaly analysis while dramatically reducing the volume of data processed, thereby lowering computational resource consumption without sacrificing analytical accuracy.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The contextual security data is segmented into relevant and irrelevant portions through the filtering mechanism. Only the segmented relevant data items that have actual bearing on the anomalous data item are passed to the analysis engine, while irrelevant segments are discarded. This segmentation approach optimizes the balance between providing sufficient context for accurate analysis and minimizing computational overhead.

Inventive Principle:
Principle #1Segmentation

2Productivity

If the context window of the analysis engine is limited, then computational efficiency is improved, but the amount of contextual information that can be processed is reduced

Engineering Contradiction:
Improvecomputational efficiencyVSAvoidcontextual information
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The filtering mechanism serves as an intermediary between the large dataset of security data items and the analysis engine's limited context window. It mediates by selecting and curating only the most pertinent non-anomalous data items, ensuring that the context window is filled with high-value information rather than redundant data. This intermediary filtering process maximizes the utilization of the limited context window while minimizing information loss.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The filtering mechanism performs preliminary action by pre-processing and curating the security data items before they reach the analysis engine. This preliminary filtering ensures that when data enters the context window, it is already optimized for relevance, allowing the analysis engine to operate efficiently within its constraints without losing critical contextual information.

Inventive Principle:
Principle #10Preliminary action

AI summary

This disclosure provides a filtering mechanism to manage anomalous security data items. An anomalous security data item is provided to an analysis engine (such as a Large Language Model (LLM) or another form of generative language model) for interpretation. By curating a selection of one or more relevant non-anomalous security data items to provide with the anomalous data item, the filtering mechanism enables the analysis engine to perform with increased accuracy, without requiring the analyst engine to process large numbers of data items to ascertain their relevance to the anomalous security data item.
