Ruggero Castagnola enhanced the frontend Content Security Policy (CSP) for the pagopa/interop-core-deployment repository by updating the img-src directive to include an additional S3 bucket, enabling secure external image loading while maintaining strict security controls. He approached this by carefully modifying YAML configuration files, ensuring that the new policy did not introduce regressions in image rendering or compromise policy enforcement. Leveraging his skills in configuration management and DevOps, Ruggero linked the changes to existing CSP governance for traceability and future audits. This work addressed resource loading friction for external media and preserved the frontend’s security and compliance posture.
