Description
OVAL XML documents are provided from several possible sources such as the CIS open source repository, or any number of vendor/3rd 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. Non-approved OVAL definitions lead to a false sense of security when evaluating an enterprise environment.
