Classification of Security Issues
Red Hat has implemented a scheme from Red Hat Enterprise Linux 4 to publicly classify the impact of security issues found in our products and services. Customers want a simple way to judge the severity of security updates so they can see which issues matter the most. The media needs guidance to understand the priority and criticality of the updates Red Hat releases. The classification scheme chosen gives a rating of security impact on a four point scale and is designed to be an at-a-glance guide to how worried Red Hat is about each security issue. This paper looks at why Red Hat has started classifying vulnerabilities, the details of the scheme we are using, and how well the classification matches our response times for Red Hat Enterprise Linux 3 vulnerabilities.
