Discussion

OVAL XML documents are provided from several possible sources such as the Community Intercomparison Suite (CIS) open-source repository and vendor/third-party paid repositories. These documents are used to automate the passive validation of vulnerabilities on systems and therefore require a reasonable level of confidence in their origin. Nonapproved OVAL definitions lead to a false sense of security when evaluating an enterprise environment.
