Solution Overview
Problem
Current risk analysis and management systems are expensive, time-consuming, and often result in inaccurate qualitative ratings due to assessor fatigue and lack of standardized industry definitions, leading to over-normalized data and inappropriate mitigation strategies without considering business costs or process impacts.

Engineering Contradiction Analysis
1Measurement precision
If quantitative security assessments are performed with extensive modeling and highly detailed data, then measurement precision is improved, but device complexity and loss of time increase significantly
Solution Approach 1:
The system segments the complex risk assessment process into distinct modules: data collection module, Monte Carlo simulation module, wildcard detection module, and reporting module. Each module handles specific aspects of the assessment, allowing the system to manage complexity through functional decomposition while maintaining high measurement precision through specialized processing in each segment.
Solution Approach 2:
The system performs preliminary actions by pre-defining attack types, requirements, and protection measures in a structured database before the actual assessment. This preliminary structuring of data models and relationships enables the system to conduct rapid Monte Carlo simulations without requiring extensive real-time data input, thus improving assessment speed while maintaining accuracy.
2Measurement precision
If Monte Carlo simulations are performed with wildcard detection and additional simulations, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The system implements feedback through wildcard detection that monitors simulation results and identifies uncertain variables. When wildcards are detected, the system automatically triggers additional targeted simulations to refine the analysis. This feedback mechanism ensures high measurement precision by focusing computational resources on critical uncertainties rather than uniformly increasing simulation counts, thus optimizing the balance between accuracy and time consumption.
3Reliability
If extensive mitigation strategies are recommended without considering business cost, then reliability is improved, but loss of substance increases
Solution Approach 1:
The system changes the parameters of mitigation recommendations by incorporating business cost and resource constraints as explicit parameters in the analysis. Rather than providing fixed extensive mitigation strategies, the system adjusts recommendation parameters based on the organization's specific resource availability, risk tolerance, and business context, enabling reliable security protection that is sustainable within actual business constraints.

AI summary
Providing a risk analysis report for an undesired event includes receiving a request comprising undesired event data defining an undesired event, wherein the undesired event data corresponds to an asset, identifying, from an attack database, one or more sets of attack attributes related to the undesired event data, and identifying one or more protection measures relevant to the asset and the attack attributes. The technique also includes performing a first set of Monte Carlo simulations for the undesired event based on combinations of the attack attributes, the protection measures, and the asset, and performing a second set of Monte Carlo simulations for the undesired event based on a subset of the combinations of the attack attribute. One or more combinations of the attack attributes, the protection measures, and the asset which result in the undesired event are provided in accordance with outcomes.
