+
+### Security Headers (Quick Look)
+
+Run:
+
+```bash
+curl -I http://127.0.0.1:3000 2>&1 | head -20
+```
+
+Paste output:
+
+```text
+HTTP/1.1 200 OK
+Access-Control-Allow-Origin: *
+X-Content-Type-Options: nosniff
+X-Frame-Options: SAMEORIGIN
+Feature-Policy: payment 'self'
+X-Recruiting: /#/jobs
+Accept-Ranges: bytes
+Cache-Control: public, max-age=0
+Last-Modified: Fri, 12 Jun 2026 17:13:54 GMT
+ETag: W/"26af-19ebcd37167"
+Content-Type: text/html; charset=UTF-8
+Content-Length: 9903
+Vary: Accept-Encoding
+Date: Fri, 12 Jun 2026 18:00:03 GMT
+Connection: keep-alive
+Keep-Alive: timeout=5
+```
+
+Which of these are MISSING?
+
+- [x] `Content-Security-Policy`
+- [x] `Strict-Transport-Security`
+- [ ] `X-Content-Type-Options: nosniff`
+- [ ] `X-Frame-Options`
+
+### Top 3 Risks Observed
+
+1. **Missing browser security headers** — The response does not include `Content-Security-Policy` and `Strict-Transport-Security`. Missing security headers reduce browser-side protection against attacks such as script injection and insecure transport behavior. This maps to **A02:2025 — Security Misconfiguration**.
+
+2. **Unauthenticated public API surface** — The `/api/Products` endpoint is accessible without authentication and returns product data in JSON format. This is normal for a public shop catalog, but exposed API endpoints still increase the attack surface and should be checked for authorization mistakes or excessive data exposure. This maps to **A01:2025 — Broken Access Control**.
+
+3. **Intentionally vulnerable application running as a local service** — OWASP Juice Shop is designed to contain security vulnerabilities for training. If it were exposed using `-p 3000:3000` instead of `127.0.0.1:3000:3000`, other devices on the network could access the vulnerable application. This maps to **A02:2025 — Security Misconfiguration**.
