## Security

### Security Headers (F — 0/100)

*0 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.
- **[WARNING]** X-Powered-By header reveals technology stack — This header discloses server technology (e.g. Express, PHP), helping attackers target known vulnerabilities. Remove it.
- **[WARNING]** Server header reveals version information — The Server header discloses the software version, aiding attackers in targeting known vulnerabilities. Remove the version number.

### 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. Consider enabling it.
- **[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 272 days)
- **[PASS]** Certificate chain has 3 certificates
- **[PASS]** Certificate uses modern signature algorithm
- **[PASS]** Certificate covers 6 domain(s)
- **[PASS]** Certificate is issued by a trusted CA

### Cookie Security (B — 80/100)

*1 cookies analyzed, 1 checks passed*

- **[CRITICAL]** Cookie 'JSESSIONID' is missing the Secure flag — Without the Secure flag, this cookie can be sent over unencrypted HTTP, exposing it to interception.
- **[PASS]** Cookie 'JSESSIONID' has the HttpOnly flag
- **[WARNING]** Cookie 'JSESSIONID' has no SameSite attribute — Without an explicit SameSite attribute, browser default behavior varies. Set SameSite=Lax or Strict.

---

## Advanced Security

### Subresource Integrity (D — 40/100)

*1 of 3 external resources have SRI*

- **[PASS]** link from use.fontawesome.com has SRI protection
- **[WARNING]** External script from ssl.google-analytics.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from www.googletagmanager.com 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 (F — 30/100)

*No DMARC*

- **[WARNING]** No DMARC record found — Without DMARC, email receivers have no policy for handling authentication failures.

### 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 (A — 90/100)

*Origin: https://marcalyc.redalyc.org*

- **[PASS]** CORS restricted to specific origin(s)
- **[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 (F — 0/100)

*6.6 MB transferred, 171 requests*

- **[CRITICAL]** Page weighs 10.9 MB (6.6 MB transferred)
- **[WARNING]** Images are 4.6 MB — compress or use modern formats — Convert images to WebP/AVIF and resize to display dimensions to reduce transfer size.
- **[WARNING]** JavaScript is 1.5 MB — consider code splitting or lazy loading — Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts.
- **[WARNING]** 171 HTTP requests — consider bundling or reducing — Each request adds latency. Bundle small files, use sprites, or eliminate unnecessary requests.
- **[INFO]** Estimated 1.4 g CO2 per page load

### Third-Party Impact (A+ — 100/100)

*18% third-party, 0 ms blocking*

- **[INFO]** Third-party code accounts for 18% of page weight (1.2 MiB of 6.6 MiB)
- **[PASS]** Third-party blocking time is low (0 ms)

### Text Compression (A+ — 100/100)

*All text resources are compressed*

- **[PASS]** All text resources are compressed

### Image Optimization (C — 60/100)

*123 images, 0 KB saveable*
