Open Vulnerability Assessment Language
What is Open Vulnerability Assessment Language?
Open Vulnerability Assessment Language, or OVAL, is a standardized language used to describe system configuration details, test for specific machine states such as vulnerabilities or configuration issues, and report the results of those assessments.
Examples
- A vulnerability scanner uses OVAL content to check whether a specific software weakness is present on a server.
- A compliance team uses OVAL definitions to test whether systems match an expected security configuration.

Security teams often need to answer very specific questions about systems. Is this vulnerability present? Is this patch missing? Does this machine match the required configuration? The challenge is not only performing the check, but describing it in a way that different tools and teams can understand consistently.
That is where OVAL becomes useful. It gives the security community a standardized way to describe what should be checked on a system and how the result should be represented. Instead of every tool inventing its own private format for the same type of assessment, OVAL helps make the content and the results more consistent and easier to share.
Summary 📝
OVAL is a standardized language for expressing security assessment content and results in a machine-readable way. It helps describe system conditions, define what should be tested, and report what the assessment found. Its real strength is not that it replaces other security tools, but that it helps them speak a more consistent language about vulnerabilities, patch status, and configuration issues.
