IDS Installation Location Selection Assistance for Network Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies for selecting the installation location of an intrusion detection system (IDS) lack specificity, making it arbitrary and requiring manual determination, which is time-consuming and labor-intensive, especially for large systems with multiple threats.
Innovation Solution
An installation location selection assistance apparatus that identifies combinations of components where an IDS can be installed and extracts those capable of detecting unauthorized communications, using system configuration input, attack information, and objective function calculations to facilitate precise location selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual determination of IDS installation locations is performed, then selection flexibility is maintained, but time consumption and labor intensity increase significantly
Solution Approach 1:
The system performs automatic installation location selection by itself without requiring manual analyst intervention. The IDS installation location selection apparatus autonomously analyzes system configurations, identifies components, evaluates combinations, and determines optimal installation locations, thereby eliminating time-consuming manual work while maintaining selection quality through automated evaluation criteria
Solution Approach 2:
The manual mechanical process of analyst review and selection is replaced with an automated computational system. The apparatus uses computer-based algorithms to perform configuration analysis, component identification, combination evaluation, and location selection, substituting human manual operations with automated information processing to reduce time consumption
2Reliability
If comprehensive analysis of all component combinations is performed, then detection coverage is improved, but system complexity increases
Solution Approach 1:
The analysis process is segmented into distinct sequential steps: configuration analysis, component identification, combination generation, combination evaluation, and location selection. This segmentation breaks down the complex comprehensive analysis into manageable modules, improving detection coverage through systematic evaluation while controlling complexity through structured process division
Solution Approach 2:
The system performs preliminary configuration analysis and component identification before generating and evaluating combinations. By preparing and organizing data in advance, the system enables comprehensive combination analysis without overwhelming complexity during the evaluation phase, as the foundation work is already completed
3Productivity
If specific installation locations are identified and limited, then selection process is streamlined, but potential detection capabilities may be reduced
Solution Approach 1:
The system dynamically adjusts the evaluation and selection process based on the specific system configuration and security requirements. Rather than using fixed predetermined locations, the apparatus adapts its analysis to identify the most appropriate installation locations for each unique scenario, ensuring both selection efficiency and optimal detection capability through context-aware dynamic evaluation

AI summary
A combination identification unit (27) identifies combinations of one or more components which constitute a target system and in each of which an intrusion detection system that detects unauthorized access can be installed. A combination reduction unit (28) extracts, from the combinations identified by the combination identification unit, a combination that satisfies an installation condition accepted by an installation condition input unit (22) and can detect unauthorized communications indicated by attack information accepted by an attack information input unit (24) at a rate higher than or equal to a threshold.
