Research Concepts View (CWE-1000)
While multiple perspectives and category-based views into CWE are very useful, a view based solely on weaknesses and their abstractions is also needed to provide a more formal mechanism for classifying weaknesses, maintaining CWE, and performing vulnerability research.
CWE-1000, the Research Concepts View (sometimes referred to as the Research view), was developed to address this need. It classifies weaknesses in a way that largely ignores how they can be detected, where they appear in code, and when they are introduced in the software development lifecycle. Accordingly, it avoids capturing relationships based on specific language, environment, technology, framework, frequency of occurrence, impact, and mitigation. (Since these relationships are convenient for many users, they are captured in CWE-699). By doing so, we have been able to concentrate on canonical factors that make each weakness unique.
