landmark found — Accessibility > Landmark Structure --- ## Lighthouse Scores | Category | Score | |----------|-------| | Performance | 44 | | Accessibility | 69 | | Best Practices | 100 | | SEO | 100 | --- ## Security ### Security Headers (F — 25/100) *2 of 10 headers properly configured* - **[WARNING]** HSTS is missing includeSubDomains — Without includeSubDomains, subdomains can still be accessed over HTTP. - **[WARNING]** X-Content-Type-Options header is missing — This header prevents MIME-type sniffing, which can lead to XSS attacks. Set it to 'nosniff'. - **[WARNING]** X-Frame-Options header is missing — This header prevents clickjacking by controlling who can embed your page in a frame. Set it to DENY or SAMEORIGIN. - **[WARNING]** Referrer-Policy header is missing — Controls how much referrer information is sent with requests. Set to 'strict-origin-when-cross-origin' or stricter. - **[WARNING]** Permissions-Policy header is missing — Controls which browser features (camera, microphone, geolocation) are allowed. Set it to restrict unused features. - **[CRITICAL]** Content-Security-Policy header is missing — CSP is the most important header for preventing XSS attacks. See the CSP section for detailed analysis. - **[WARNING]** Cross-Origin-Opener-Policy header is missing — COOP isolates your browsing context, preventing cross-origin side-channel attacks. Set to 'same-origin'. - **[WARNING]** Cross-Origin-Embedder-Policy header is missing — COEP prevents loading cross-origin resources without explicit permission. Required for SharedArrayBuffer and high-resolution timers. - **[PASS]** X-Powered-By header is not present - **[PASS]** Server header is present without version info ### Content Security Policy (F — 0/100) *No enforcing CSP policy found* - **[CRITICAL]** No Content-Security-Policy header found — CSP is the most effective defense against XSS attacks. Add a Content-Security-Policy header to restrict resource loading. ### TLS & Certificates (A+ — 100/100) *TLS 1.2, 7 checks passed* - **[PASS]** TLS 1.2 is used - **[INFO]** TLS 1.3 is not negotiated — TLS 1.3 offers improved performance and security.
