Tod B. established the foundational KEV data catalog for the cisagov/kev-data repository, focusing on scalable data management and open source contribution practices. He architected the repository scaffolding, integrating governance documentation, contribution workflows, and essential boilerplate files such as SECURITY.md and issue templates. Using CSV and Markdown, Tod populated the initial known_exploited_vulnerabilities.csv with detailed CVE and mitigation data, enabling reproducible and compliant data curation. His work addressed the need for secure collaboration and ongoing vulnerability management, laying a robust groundwork for future data ingestion and quality checks. The depth of his approach supports sustainable, community-driven KEV data governance.
