Worked on security hardening for Canvas Apps in the MicrosoftDocs/power-platform repository, focusing on restoring strict Content Security Policy (CSP) support to reduce misconfigurations and strengthen data protection. Addressed a key bug by carefully reverting previous changes, ensuring secure-by-default configurations without disrupting related features. Emphasized alignment with security baselines and compliance requirements, using Markdown for documentation and applying security best practices throughout the process. The approach prioritized operational risk reduction for customers deploying Canvas Apps, delivering clear business value by reinforcing policy enforcement and minimizing exposure to CSP-related vulnerabilities. Demonstrated attention to detail and collaborative problem-solving in a documentation-driven environment.
