WAF Step 5 Review

🎉 WAF Creation Success:

  • WAF tạo xong trong 1-2 phút
  • Associate với CloudFront ở bước tiếp theo
  • Monitor metrics trong CloudWatch console
  • Test protection sau khi associate
  1. Web ACL Configuration Summary:

    • Name: VinaShoesImagesWAF
    • Type: CloudFront protection
    • Default action: Allow (with managed rules blocking attacks)
    • Cost: Free tier covers basic rules + 1M requests/month
  2. Verify WAF Creation:

    • WAF Console → Web ACLs → Should see VinaShoesImagesWAF
    • Status: Active
    • Associated resources: None (sẽ associate với CloudFront ở section 3.3.3)

WAF Created Successfully

🚨 Default Action Strategy:

  • Allow (Recommended): Cho phép tất cả traffic, chỉ block specific patterns
  • Block: Chặn tất cả traffic trừ whitelist (rất nguy hiểm!)
  • Best Practice: Bắt đầu với Allow + monitor, sau đó tối ưu rules

⚠️ Rate Limiting Considerations:

  • Too strict: Có thể block legitimate users (mobile users, office NAT)
  • Too loose: Không hiệu quả chống DDoS
  • Recommended: Start với 2000 req/5min, monitor và adjust
  • Geographic blocking: Consider blocking specific countries nếu không có customers

3.3.2. Configure Custom Rules

Create Custom Rule - Block Suspicious User Agents:

{
  "Name": "BlockSuspiciousUserAgents",
  "Priority": 500,
  "Statement": {
    "ByteMatchStatement": {
      "SearchString": "bot|crawler|scanner|scraper",
      "FieldToMatch": {
        "SingleHeader": {
          "Name": "user-agent"
        }
      }
    }
  },
  "Action": {
    "Block": {}
  }
}

🎯 Custom Rules Ideas:

  • Geographic restrictions: Block traffic từ specific countries
  • User-Agent filtering: Block suspicious crawlers/bots
  • Referrer validation: Block hotlinking từ malicious sites
  • File extension blocking: Block access to .env, .config files
  • API endpoint protection: Rate limit specific API paths

3.4. AWS Amplify Hosting (Next.js)

🎯 Objective: Deploy Next.js Frontend với GitHub CI/CD tự động, auto-scaling, và production-ready hosting

            - npm run generate-sitemap
            
            # Optimize images (if needed)
            - npm run optimize-images
            
      artifacts:
        baseDirectory: out
        files:
          - '**/*'
      cache:
        paths:
          - node_modules/**/*
          - .next/cache/**/*
    
    # Custom headers for security và performance
    customHeaders:
      - pattern: '**/*'
        headers:
          - key: 'X-Frame-Options'
            value: 'DENY'

3.4.5. Custom Domain Configuration (Using Domain from Task 2)

🔗 Task 2 Integration: Sử dụng domain vinashoes.org đã setup từ Task 2 (Cloudflare Registrar + DNS)

  • Domain: vinashoes.org (already registered qua Cloudflare)
  • DNS Management: Cloudflare DNS (DNS-only mode)
  • SSL Strategy: Amplify ACM + Cloudflare DNS validation
  • Architecture: Cloudflare DNS → Amplify hosting (perfect integration!)

⚠️ Domain Configuration Strategy: Vì domain đã được setup trong Task 2 với Cloudflare, chúng ta sẽ:

  • Manual configuration: Sử dụng Cloudflare DNS existing setup
  • KHÔNG transfer nameservers sang Amplify (sẽ break existing setup)
  • DNS validation: Through Cloudflare DNS records
  • Maintain control: Keep Cloudflare as DNS provider

1. Add Custom Domain (Current Step):

  • Domain field: www.vinashoes.org (như screenshot)
  • Click “Configure domain”

Current Amplify Add Domain Screen

2. Choose DNS Configuration Method:

Select “Manual configuration” (REQUIRED for Cloudflare DNS):

  • Manual configuration ← Select this option
  • NOT “Create hosted zone on Route 53” (sẽ conflict với Cloudflare)

Amplify DNS Configuration Choice

💡 Why Manual Configuration?

  • Preserve Task 2 setup: Giữ nguyên Cloudflare DNS management
  • Cost effective: Không tạo Route 53 hosted zone ($6/năm)
  • No conflicts: Tránh DNS conflicts giữa providers
  • Consistent architecture: Duy trì strategy từ Task 2

3. Domain Configuration Details:

  • Domain: www.vinashoes.org
  • Branch: main (production)
  • Custom SSL certificate
    • SSL certificate: Generated via ACM ở task 2
    • Validation method: DNS validation through Cloudflare

Amplify Domain Configuration Amplify SSL Validation Records

4. SSL Certificate Validation: Sau khi clicking “Configure domain”, Amplify sẽ provide:

  • CNAME record cho SSL validation
  • Target domain cho website pointing

Amplify SSL Validation Records Cloudflare Add SSL Validation

5. Add DNS Records in Cloudflare:

  1. Go to Cloudflare DashboardDNSRecords
  2. Click “Add record”
  3. Type: CNAME
  4. Name: Copy từ Amplify (e.g., _amazonawsacm.www)
  5. Target: Copy từ Amplify validation target
  6. Proxy status: OFF (DNS only)
  7. Click “Save”

Cloudflare Add SSL Validation

🚨 Critical Cloudflare Settings:

  • Proxy status MUST be OFF: Orange cloud = ON sẽ conflict với Amplify SSL
  • TTL: Auto hoặc 300 seconds cho faster propagation
  • Priority: Không cần cho CNAME records
  • Wait for validation: SSL validation có thể mất 5-15 phút

6. Monitor Domain Status:

Trong Amplify Console, domain status sẽ progress through:

  1. Pending validation → Waiting cho DNS records
  2. Pending verification → Checking SSL certificate
  3. Available → Domain ready for traffic
  4. Failed → Check DNS records và retry
