## Security

### Security Headers (F — 35/100)

*3 of 10 headers properly configured*

- **[WARNING]** HSTS max-age is too short (0s, should be ≥ 31536000s) — A short max-age leaves a window for downgrade attacks. Set max-age to at least 31536000 (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.
- **[PASS]** Content-Security-Policy is present
- **[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 (C — 65/100)

*2 of 10 CSP checks passed*

- **[INFO]** Raw CSP policy
- **[WARNING]** default-src directive is missing — default-src provides a fallback for other directives. Set it to restrict default resource loading.
- **[INFO]** No script-src or default-src to check for 'unsafe-inline'
- **[INFO]** No script-src or default-src to check for 'unsafe-eval'
- **[INFO]** No script-src or default-src to check for wildcard
- **[PASS]** object-src falls back to default-src
- **[WARNING]** base-uri directive is missing — Without base-uri, attackers can inject a <base> tag to hijack relative URLs. Set it to 'self' or 'none'.
- **[WARNING]** frame-ancestors directive is missing — frame-ancestors controls who can embed your page, preventing clickjacking. Set it to 'self' or 'none'.
- **[WARNING]** form-action directive is missing — form-action restricts where forms can submit data, preventing form hijacking.
- **[PASS]** upgrade-insecure-requests is enabled

### 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 74 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 (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 2 external resources have SRI*

- **[WARNING]** External link from fonts.googleapis.com lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External link from ufsc3.paginas.ufsc.br 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 (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 (F — 0/100)

*25.0 MB transferred, 138 requests*

- **[CRITICAL]** Page weighs 27.6 MB (25.0 MB transferred)
- **[WARNING]** Images are 23.3 MB — compress or use modern formats — Convert images to WebP/AVIF and resize to display dimensions to reduce transfer size.
- **[WARNING]** JavaScript is 1.0 MB — consider code splitting or lazy loading — Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts.
- **[INFO]** CSS is 589 KB — consider purging unused styles — Remove unused CSS rules with tools like PurgeCSS to reduce stylesheet size.
- **[WARNING]** 138 HTTP requests — consider bundling or reducing — Each request adds latency. Bundle small files, use sprites, or eliminate unnecessary requests.
- **[INFO]** Estimated 5.2 g CO2 per page load

### Third-Party Impact (D — 50/100)

*97% third-party, 0 ms blocking*

- **[WARNING]** Third-party code accounts for 97% of page weight (24.2 MiB of 25.0 MiB)

*All text resources are compressed*

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

### Image Optimization (C — 60/100)

## Infrastructure

### DNS Records (A — 85/100)

*1 A records, 384 ms lookup*

- **[PASS]** Resolves to 1 IPv4 address(es)
- **[INFO]** Single A record — no DNS redundancy — Multiple A records provide failover if one server goes down.
- **[PASS]** Has 1 IPv6 (AAAA) record(s)
- **[PASS]** 2 nameserver(s) configured
- **[PASS]** 1 mail exchanger(s) configured
- **[INFO]** CAA records not checked — CAA record lookup requires a specialized DNS resolver. This check will be available in a future update.
- **[PASS]** SPF record present in TXT
- **[WARNING]** DNS resolution is slow (384 ms) — Slow DNS adds latency to every page load. Consider a faster DNS provider.

### Redirect Chain (A+ — 100/100)

*No redirects — direct access*

- **[PASS]** No redirects — direct access

### IPv6 Readiness (F — 30/100)

*IPv6 records exist but unreachable*

- **[WARNING]** IPv6 DNS records exist but server is not reachable — Having AAAA records but an unreachable server is worse than no AAAA — clients may experience delays before falling back to IPv4.
- **[INFO]** IPv6 connection error

### Crawlability (B — 75/100)

*no robots.txt, no sitemap*

- **[INFO]** No robots.txt found — robots.txt is optional but recommended. It tells search engine crawlers which pages to index.
- **[INFO]** No sitemap.xml found — A sitemap helps search engines discover and index your pages more efficiently.

### URL Variants (A+ — 100/100)

*www/non-www, trailing slash, HTTP→HTTPS*

- **[PASS]** www/non-www redirect configured correctly (preferred: non-www)
