## 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 not present

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

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