The OVAL Interpreter is a freely available reference implementation that demonstrates the evaluation of OVAL Definitions. Based on a set of OVAL Definitions the interpreter collects system information, evaluates it, and generates a detailed OVAL Results file. Developed to demonstrate the usability of OVAL Definitions and to ensure correct syntax and adherence to the OVAL Schemas by definition writers, it is not a fully functional scanning tool nor an enterprise scanning tool. It is a simplistic, command-line application that has the ability to execute OVAL Content on an end system. To learn more about organizations that provide OVAL content and tools or otherwise support the OVAL Language, please see the OVAL Adoption Program (http://oval.mitre.org/adoption/).
