A new day in the Trading competition of @STRATO_MERCATA. Today i wrote a full Security Header Report Summary: Security Headers Report Summary, Grade: F — Most recommended HTTP security headers are missing: 1. Missing: Content-Security-Policy Helps prevent cross-site scripting (XSS) and code injection. ➤ *Recommendation:* Add a strict policy like default-src 'self';. 2. Missing: X-Content-Type-Options Prevents browsers from MIME-sniffing responses. ➤ *Recommendation:* Add X-Content-Type-Options: nosniff. 3. Missing: Strict-Transport-Security (HSTS) Ensures all traffic uses HTTPS, even if users type "http". ➤ *Recommendation:* Add Strict-Transport-Security: max-age=63072000; includeSubDomains. 4. Missing: X-Frame-Options Protects against clickjacking by preventing embedding in iframes. ➤ *Recommendation:* Use X-Frame-Options: DENY or SAMEORIGIN. 5. Missing: X-XSS-Protection Enables browser XSS filtering (mostly legacy). ➤ *Recommendation:* Add X-XSS-Protection: 1; mode=block *(optional in modern browsers)*. 6. Missing: Referrer-Policy Controls how much referrer info is shared during navigation. ➤ *Recommendation:* Use Referrer-Policy: strict-origin-when-cross-origin. 7. Missing: Permissions-Policy (formerly Feature-Policy) Restricts access to sensitive browser features (e.g. camera, mic). ➤ *Recommendation:* Use e.g. Permissions-Policy: geolocation=(), camera=(). 🙏📖✍️
