Worked on hardening the AWS-based infrastructure for the skuba repository by applying a critical security patch to address potential account takeover risks. Focused on dependency management and security patching, the work involved updating the AWS CDK to version 2.167.1 and ensuring all related dependencies in pnpm-lock.yaml were current. Maintained traceability and transparency by documenting the mitigation in the project’s changelog. The approach prioritized stability and secure release practices, using yaml for configuration management. This effort reduced security risk without introducing new features, demonstrating a methodical approach to maintaining infrastructure integrity and upholding best practices in secure software maintenance.
