Why OVAL Feeds Outperform NVD for Linux Vulnerability Management
Blog post from Endor Labs
Discrepancies in container scanning results often arise from differences in data sources, with the National Vulnerability Database (NVD) providing generalized vulnerability information that can lead to false positives, while the Open Vulnerability and Assessment Language (OVAL) offers more precise, context-specific data tailored by Linux distribution maintainers. This is exemplified by CVE-2022-1587, where the NVD rated the vulnerability as "Critical" based on broad criteria, while Ubuntu assessed it as "Low" due to specific mitigations and backported fixes. OVAL feeds, maintained by major Linux distributors like Red Hat, Ubuntu, and Debian, deliver validated information that reflects the actual risk level within specific environments, reducing unnecessary remediation efforts and focusing on real security threats. Endor Labs leverages OVAL feeds in its container scanning solution to provide accurate vulnerability data, offering features such as routine scans, strong container signatures, and automated correlation of vulnerabilities, ultimately improving software supply chain security and enhancing the developer's experience.
