Open Vulnerability and Assessment Language (OVAL) is an international, information security, community standard to promote open and publicly available security content, and to standardize the transfer of this information across the entire spectrum of security tools and services. OVAL includes a language used to encode system details, and an assortment of content repositories held throughout the community. The language standardizes the three main steps of the assessment process :

Representing configuration information of systems for testing;
Analyzing the system for the presence of the specified machine state (vulnerability, configuration, patch state, etc.);
Reporting the results of this assessment.
