A Practical Guide to Enhancing EBIOS RM with FAIR Quantification
EBIOS Risk Manager provides a structured approach to identifying and analyzing cyber risks but it stops short of telling you how severe those risks actually are in financial terms. Without quantification, risk prioritization remains subjective and difficult to defend at the executive level.
This paper shows how integrating FAIR with EBIOS RM closes that gap, without requiring you to abandon your existing practices.
· Why EBIOS RM alone isn't enough: how the absence of financial quantification leads to inconsistent, bias-prone assessments that struggle to inform strategic decisions
· How FAIR complements EBIOS RM: a step-by-step mapping of both methodologies across the five EBIOS RM workshops, showing where FAIR quantification fits naturally
· The concrete benefits of integration: from more objective risk prioritization and cost-benefit analysis of security measures, to clearer communication with executives and boards
· Alignment with key standards: how this combined approach maps to ISO 27001, ISO 27005, and the Open FAIR Body of Knowledge
