For the past 5 years, CVE has been tracking the types of errors that lead to publicly reported vulnerabilities, and periodically reporting trends on a limited scale. In support of the Common Weakness Enumeration (CWE) project, and as a result of the interest in this work as mentioned during the “Year of the web application: Hack & Data from the Front lines” panel at the 5th Annual Cyber Security Executive Summit in New York City on September 13, 2006, we have published a more extensive analysis. An updated version will be released once 2006 is complete.
The primary goal of this study is to better understand research trends using publicly reported vulnerabilities. It should be noted that the data is obtained from an uncontrolled population, i.e., decentralized public reports from a research community with diverse goals and interests, with an equally diverse set of vendors and developers. More specialized, exhaustive, and repeatable methods could be devised to evaluate software security. But until such methods reach maturity and widespread acceptance, the overall state of software security can be viewed through the lens of public reports.
