How CVSS Works: A Guide to Vulnerability Scoring

Leave a Reply

The Common Vulnerability Scoring System (CVSS) is a widely used framework for evaluating and communicating the severity of software vulnerabilities. First introduced in 1999, CVSS has become the standard scoring method for organisations to prioritise security efforts and manage vulnerabilities systematically. By assigning numerical scores to vulnerabilities based on their characteristics, CVSS enables teams to assess risks and allocate resources effectively.

The Evolution of FAIR: Cyber Risk in Financial Terms

Leave a Reply

The Factor Analysis of Information Risk (FAIR) framework has emerged as a cornerstone in cyber risk quantification, enabling organisations to measure and communicate risk in financial terms. FAIR’s evolution represents a shift from traditional qualitative assessments to a structured, quantitative model that aligns cybersecurity strategies with business objectives. By breaking down risk into probability and impact components, FAIR provides decision-makers with actionable insights to prioritise investments and mitigate threats effectively.
