Charlie Bravo focused on security-hardening for the include-dcc/include-portal-ui repository, delivering a comprehensive suite of HTTP security headers and a refined Content Security Policy. By implementing protections such as XSS mitigation, Referrer Policy, X-Content-Type-Options, and Feature Policy, Charlie addressed common web security risks and aligned the portal with enterprise security baselines. The work included a targeted cleanup of the CSP to remove redundancies, improving maintainability and reducing misconfiguration risk. Using skills in HTTP headers and web security, Charlie’s changes enhanced the team’s ability to audit configurations and ensured the portal’s headers behaved as intended without introducing vulnerabilities.
