Tabatha DiDomenico focused on enhancing security governance for the finos/git-proxy repository by updating its SECURITY.md documentation. She implemented a security policy update using Markdown, aligning the repository with FINOS reporting standards and clarifying vulnerability disclosure workflows. Her work emphasized documentation and security policy skills, ensuring that preferred reporting methods and incident response processes were clearly communicated to contributors. By delivering a policy-level change with minimal risk to production, Tabatha improved transparency and prepared the repository for consistent vulnerability reporting. The update laid a foundation for better security posture and streamlined compliance with established FINOS security protocols within the project.
