Worked on security hardening for the Java authentication provider in the affinidi/affinidi-tdk repository, focusing on remediating vulnerabilities reported by Snyk. Addressed these issues by upgrading dependencies and applying a targeted patch to the pom.xml file, leveraging skills in dependency management and security vulnerability remediation. This approach reduced the module’s exposure to known risks and improved its overall security posture. The work was documented to support traceability and future audits, aligning with compliance requirements. Utilized XML for configuration management, ensuring that the authentication module met higher security standards without introducing new features, and contributed to improved risk management for stakeholders.
