Abstract
This poster introduces Cx, an expert-based composite index for assessing ICT-related risk in adversarial organizational contexts. The index estimates an organization's defensive capability against cyber adversaries by combining technical, organizational, and attacker-oriented factors in a weighted scoring model. The method was developed through a literature-informed design process and an expert-panel refinement stage. The paper describes factor definitions, scoring rules, weighting logic, and interpretation ranges, and positions Cx as a decision-support tool for managers and information systems governance. A compact illustrative comparison shows how Cx supports structured comparison and communication of assessment results. The poster positions Cx as a preliminary methodological artifact requiring empirical validation.
