## 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 1.3, 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 125 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 4 external resources have SRI*

- **[WARNING]** External script from atlas.is.cuni.cz lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from atlas.is.cuni.cz lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from atlas.is.cuni.cz lacks integrity attribute — Without SRI, if this CDN is compromised, attackers could inject malicious code.
- **[WARNING]** External script from atlas.is.cuni.cz 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*

- **[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 (B — 80/100)

*No CORS headers*

- **[PASS]** No CORS headers present — secure default

---

## Performance

### Page Weight Budget (F — 0/100)

*7.9 MB transferred, 102 requests*

- **[CRITICAL]** Page weighs 13.8 MB (7.9 MB transferred)
- **[WARNING]** Images are 5.3 MB — compress or use modern formats — Convert images to WebP/AVIF and resize to display dimensions to reduce transfer size.
- **[WARNING]** JavaScript is 2.1 MB — consider code splitting or lazy loading — Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts.
- **[INFO]** CSS is 201 KB — consider purging unused styles — Remove unused CSS rules with tools like PurgeCSS to reduce stylesheet size.
- **[WARNING]** 102 HTTP requests — consider bundling or reducing — Each request adds latency. Bundle small files, use sprites, or eliminate unnecessary requests.
- **[INFO]** Estimated 1.7 g CO2 per page load

### Third-Party Impact (A — 85/100)

*24% third-party, 0 ms blocking*

- **[INFO]** Third-party code accounts for 24% of page weight (1.9 MiB of 7.9 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)
