Quantifying Cyber Security Risk through Interest Rate Calculation in Debt Management

Abstract

This paper introduces a novel Interest Rate Calculation Model for cyber security risk quantification, addressing the challenges of cyber security debt management. Unlike traditional qualitative risk assessments, this model applies financial principles to quantify risk impact dynamically, integrating seamlessly with industry frameworks. By framing cyber security risks in financial terms, the model enhances decision-making, promotes strategic resource allocation, and fosters stakeholder engagement. Through a structured methodology, it empowers organisations to assess, prioritise, and mitigate cyber security debt efficiently, ensuring long-term resilience in an evolving threat landscape.
