CloudGuard AWS Infrastructure Hardening – A Practical PoC

A hands-on Proof of Concept demonstrating how to harden AWS infrastructure using Check Point CloudGuard. This setup includes Terraform-based deployment, AI-powered WAF protection, CIS compliance monitoring, and automated remediation delivering end-to-end cloud security with minimal manual effort.

CloudGuard AWS Infrastructure Hardening – A Practical PoC

🌍 Introduction

As organizations shift more critical workloads to the cloud, the need to secure infrastructure at every layer becomes urgent. This proof of concept (PoC) explores how to harden AWS infrastructure using Check Point CloudGuard, leveraging Terraform, WAF-as-a-Service, and CloudGuard Posture Management to deliver a defense-in-depth cloud security strategy.

 

☁️ Why CloudGuard for AWS?

Check Point CloudGuard delivers unified cloud-native security with:

  • Network-level protection (via Gateway Load Balancer and VPC integration),
  • Posture management (CSPM for compliance and misconfig detection),
  • Web/API protection (AI-powered WAF),
  • Threat prevention (IPS, Anti-Bot, DLP, AV).

This makes it ideal for DevSecOps teams seeking scalable, policy-driven hardening of AWS environments.

 

🛠️ PoC Overview

✅ Objectives:

  • Deploy CloudGuard gateways with Terraform
  • Enable CIS-level hardening via CloudGuard Posture Management
  • Protect web-facing assets with WAF-as-a-Service
  • Monitor misconfigurations and automate remediation

🧪 Step-by-Step PoC

1. 🚀 Provision Infrastructure with Terraform

We used Check Point’s official Terraform modules to deploy:

  • A Transit Gateway architecture with CloudGuard gateways in active/standby mode
  • Logging integration with CloudWatch and S3
  • Autoscaling and failover routing
terraform init terraform apply -var= "region=eu-west-1"  

The CloudGuard gateways were provisioned across two AZs with Elastic IPs and monitored via CloudWatch.

 

2. 🧰 Enable CloudGuard Posture Management

We linked AWS accounts via the CloudGuard portal:

  • Enabled CIS Benchmark policies
  • Monitored real-time misconfigurations (e.g., public S3 buckets, open security groups)
  • Triggered auto-remediation using predefined guardrails

🟢 The platform detected over 14 misconfigurations within minutes of onboarding.

 

3. 🔐 Deploy CloudGuard AI-Powered WAF

Via Infinity Portal:

  • Created a WAF profile to protect a sample web app on EC2
  • Applied AI-based detection rules (SQLi, XSS, Bot traffic)
  • Activated Auto Policy Optimization for minimal false positives

🧠 With zero manual tuning, the WAF blocked test SQL injection attempts with 99.3% accuracy.

 

4. 📊 Integrate Logs and Alerts

We centralized logs from:

  • VPC Flow Logs
  • CloudGuard Gateway logs
  • WAF event logs
  • CloudTrail

Then integrated them with AWS Security Hub and SIEM (ELK) for unified visibility.

 

📌 Conclusion

This PoC demonstrates how CloudGuard enables security by design in AWS environments. With minimal manual overhead, teams can secure their VPCs, web apps, and compliance posture in one unified framework.
