+
+## 1. API Authentication Verification (4.2.3)
+
+```bash
+# Test unauthenticated API access (should return 401)
+curl -s -o /dev/null -w "%{http_code}" \
+  http://localhost:8080/api/v1/predict
+
+# Test with invalid token (should return 403)
+curl -s -o /dev/null -w "%{http_code}" \
+  -H "Authorization: Bearer invalid_token" \
+  http://localhost:8080/api/v1/predict
+```
+
+---
+
+## 2. TLS Configuration Check (4.2.2)
+
+```bash
+# Verify TLS version and cipher suites
+openssl s_client -connect <AI_API_HOST>:443 -tls1_2 </dev/null 2>/dev/null | \
+  grep -E "Protocol|Cipher"
+
+# Check for weak ciphers
+nmap --script ssl-enum-ciphers -p 443 <AI_API_HOST>
+
+# Verify certificate validity

+  openssl x509 -noout -dates
+```
+
+---
+
+## 3. Rate Limiting Verification (3.4.2, 5.1.4)
+
+```bash
+# Test rate limiting with rapid sequential requests
+for i in $(seq 1 100); do
+  STATUS=$(curl -s -o /dev/null -w "%{http_code}" \
+    -H "Authorization: Bearer $TOKEN" \

+  echo "Request $i: $STATUS"
+  [ "$STATUS" = "429" ] && echo "Rate limit triggered at request $i" && break
+done
+```
+
+---
+
+## 4. Input Validation & Prompt Injection Check (3.2.1, 3.4.7)
+
+```bash
+# Test input size limits
+python3 -c "
+import requests
+# Oversized input test (should return 413 or 400)
+payload = {'input': 'A' * 1000000}
+r = requests.post('http://localhost:8080/api/v1/predict',

+    print(f'Injection test: {r.status_code} - blocked={r.status_code in [400,403]}')
+"
+```
+
+---
+
+## 5. API Logging & Audit Trail (5.1.4)
+
+```bash
+# Verify API access logs exist and contain required fields
+# Required fields: timestamp, user_id, endpoint, input_hash, response_code, latency
+tail -20 /var/log/ai-service/access.log
+
+# Check for sensitive data leakage in logs
+grep -rn "password\|secret\|api_key\|token" /var/log/ai-service/ 2>/dev/null
+```
+
+---
+
+## 6. CORS & Security Headers Check (4.2.1)
+
+```bash
+# Check CORS configuration
+curl -s -I -H "Origin: http://evil.com" \
+  http://localhost:8080/api/v1/predict | \
+  grep -i "access-control"
+
+# Verify security headers
+curl -s -I http://localhost:8080/api/v1/predict | \
+  grep -iE "x-content-type|x-frame-options|strict-transport|content-security-policy"
+```
+
+---
+
+## 7. Least Privilege API Scope Check (4.2.4)
+
+```bash
+# List all exposed API endpoints
+curl -s http://localhost:8080/api/docs | \
+  python3 -c "import sys,json; [print(f'{m} {p}') for p,v in json.load(sys.stdin).get('paths',{}).items() for m in v]"
+
+# Check for admin/debug endpoints exposed to public
+curl -s -o /dev/null -w "%{http_code}" http://localhost:8080/api/v1/admin/config
+curl -s -o /dev/null -w "%{http_code}" http://localhost:8080/api/v1/debug
+curl -s -o /dev/null -w "%{http_code}" http://localhost:8080/metrics
+```

+
+## Verification Checklist
+
+| Item | Check | Expected |
+|------|-------|----------|
+| Unauthenticated access | `curl` without token | 401 Unauthorized |
+| Invalid token | `curl` with bad token | 403 Forbidden |
+| TLS version | `openssl s_client` | TLS 1.2+ only |
+| Rate limiting | 100 rapid requests | 429 before 100 |
