🧪 Testing & Validation

Part 1: F5 WAF Testing

Before Production Deployment

Each scenario provides:

Curl Examples: Ready-to-use attack simulation
TMSH Show Commands: Real-time policy verification
ASM Log Queries: Filter and analyze security events
Success Criteria: Expected blocking/allowing behavior

Example: Test Brute-Force Protection

# Test 1: Generate 5 failed login attempts
for i in {1..5}; do
  curl -X POST http://bigip_host/login \
    -d "username=admin&password=wrong" \
    -H "Content-Type: application/x-www-form-urlencoded"
done

# Test 2: Verify IP is blocked on 6th attempt
curl -X POST http://bigip_host/login \
  -d "username=admin&password=correct"
# Expected: 403 Forbidden with custom response

Part 2: Web Server Hardening Testing

1. Security Headers Verification

# Check specific header
curl -I https://yourdomain.com | grep "Strict-Transport-Security"

# Full header dump
curl -v https://yourdomain.com 2>&1 | grep "^<"

2. SSL/TLS Grade Testing (Target: A+ or A)

Visit: https://www.ssllabs.com/ssltest/
Enter your domain
Verify: TLS 1.2/1.3 only, strong ciphers, no weak protocols

3. Security Headers Score (Target: A or A+)

Visit: https://securityheaders.com/
Enter your domain
Verify: All recommended headers present

4. Server Configuration Syntax Test

# NGINX
nginx -t

# Apache
apache2ctl configtest
# or
httpd -t

# Tomcat (check catalina.out logs after restart)
tail -f logs/catalina.out

5. Certificate Validation

# Check certificate details
openssl s_client -connect yourdomain.com:443 -showcerts

# Verify OCSP stapling (if configured)
openssl s_client -connect yourdomain.com:443 -ocsp
