landmark found — Accessibility > Landmark Structure --- ## Lighthouse Scores | Category | Score | |----------|-------| | Performance | 42 | | Accessibility | 84 | | Best Practices | 92 | | SEO | 100 | --- ## Security ### Security Headers (F — 10/100) *2 of 10 headers properly configured* - **[CRITICAL]** HSTS header is missing — Strict-Transport-Security forces browsers to use HTTPS, preventing downgrade attacks. Add the header with a max-age of at least 1 year. - **[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 not present ### 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 1.3, 7 checks passed* - **[PASS]** TLS 1.3 is used - **[PASS]** Strong cipher suite is used - **[INFO]** HTTP/2 is not negotiated — HTTP/2 provides multiplexing and header compression for better performance. - **[PASS]** Certificate is valid (expires in 326 days) - **[PASS]** Certificate chain has 2 certificates - **[PASS]** Certificate uses modern signature algorithm - **[PASS]** Certificate covers 2 domain(s) - **[PASS]** Certificate is issued by a trusted CA ### Cookie Security (A+ — 95/100) *1 cookies analyzed, 2 checks passed* - **[PASS]** Cookie 'ngtoken' has the Secure flag - **[WARNING]** Cookie 'ngtoken' is missing the HttpOnly flag — Without HttpOnly, this cookie can be accessed by JavaScript, making it vulnerable to XSS-based theft. - **[PASS]** Cookie 'ngtoken' has SameSite=None --- ## Advanced Security ### Subresource Integrity (A+ — 100/100) *No external resources* - **[PASS]** No external resources to protect ### JS Library Vulnerabilities (A+ — 100/100) *No known vulnerabilities* - **[PASS]** No known JavaScript library vulnerabilities detected ### Information Leakage (A+ — 100/100) *No exposures* - **[PASS]** security.txt is present — good practice - **[PASS]** No sensitive files exposed ### Email Security (A — 85/100) *DMARC: quarantine* - **[PASS]** DMARC policy is quarantine — good protection ### Permissions-Policy (D — 40/100) *No header set* - **[WARNING]** No Permissions-Policy header — Consider adding a Permissions-Policy header to restrict browser feature access from embedded content. ### CORS Configuration (C — 60/100) *Origin: ** - **[INFO]** Access-Control-Allow-Origin: * — unrestricted — Any website can read this resource's response. Appropriate for public APIs but not for user-specific content. - **[INFO]** Origin reflection not testable with a single request — Some servers reflect the request Origin header. This requires manual testing with a crafted Origin header. --- ## Performance ### Page Weight Budget (B — 78/100) *1.3 MB transferred, 230 requests* - **[PASS]** Page weighs 2.9 MB (1.3 MB transferred) - **[WARNING]** JavaScript is 656 KB — consider code splitting or lazy loading — Large JavaScript bundles delay interactivity.
