## 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.

*1.00g CO2 per view*

- **[INFO]** 1.00g CO2 per page view — This page transfers 4.2 MB, producing an estimated 1.00g of CO2 per visit using the Sustainable Web Design model (v4). Breakdown: data center 0.03g, network 0.21g, end-user device 0.77g.
- **[INFO]** At 10,000 monthly views: 119.8 kg CO2/year — With 10,000 page views per month, this page would generate approximately 119.8 kg of CO2 annually — equivalent to charging 14978 smartphones.

### Carbon Budget (D — 50/100)

*61th percentile*

- **[WARNING]** 1.00g CO2 — above the median website (0.60g) — Heavier than an estimated 39% of websites. Reducing page weight, optimizing images, and removing unused JavaScript would lower the carbon footprint. See the Performance tab.
- **[INFO]** Estimated 61th percentile — Compared to: top 10% = 0.20g, target = 0.50g, median = 0.60g per page view.

### Transfer Efficiency (C — 60/100)

*61% efficient*

- **[WARNING]** Transfer efficiency: 61% — An estimated 1699 KB (39%) could be eliminated: 0 KB via better compression, 0 KB via modern image formats, 1699 KB of unused JavaScript. This wasted data produces 0.39g of unnecessary CO2 per page view.
