## Security

### Security Headers (F — 25/100)

*3 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.
- **[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

- **[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*
