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'. - **[PASS]** X-Frame-Options is properly configured - **[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 1.3, 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 244 days) - **[PASS]** Certificate chain has 3 certificates - **[PASS]** Certificate uses modern signature algorithm - **[PASS]** Certificate covers 2 domain(s) - **[PASS]** Certificate is issued by a trusted CA ### Cookie Security (B — 75/100) *1 cookies analyzed, 0 checks passed* - **[CRITICAL]** Cookie 'PHPSESSID' is missing the Secure flag — Without the Secure flag, this cookie can be sent over unencrypted HTTP, exposing it to interception. - **[WARNING]** Cookie 'PHPSESSID' is missing the HttpOnly flag — Without HttpOnly, this cookie can be accessed by JavaScript, making it vulnerable to XSS-based theft. - **[WARNING]** Cookie 'PHPSESSID' has no SameSite attribute — Without an explicit SameSite attribute, browser default behavior varies. Set SameSite=Lax or Strict. --- ## Advanced Security ### Subresource Integrity (F — 20/100) *0 of 1 external resources have SRI* - **[WARNING]** External script from matomo.gwdg.de lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code. ### JS Library Vulnerabilities (A+ — 100/100) *No known vulnerabilities* - **[PASS]** No known JavaScript library vulnerabilities detected ### Information Leakage (A+ — 100/100) *No exposures* - **[INFO]** No security.txt found — Consider adding a security.txt at /.well-known/security.txt. - **[PASS]** No sensitive files exposed ### Email Security (D — 50/100) *DMARC: none* - **[WARNING]** DMARC policy is none — monitoring only — This only monitors, it doesn't block spoofed emails.
