Deep Dive into AWS Network Firewall

AWS Network Firewall is a managed service that makes it easy to deploy essential network protections for all of your Amazon Virtual Private Clouds (VPCs).

Key Features

  1. Stateful Inspection: Inspects traffic based on protocols and port, or even regex patterns.
  2. VPC Integration: Deploys into your VPCs automatically with a few clicks.
  3. Managed Rules: Use AWS managed rule groups for common threats.

Implementation Steps

  1. Create Firewall Policy: Define stateless and stateful rule groups.
  2. Create Firewall: Associate the policy with a specific VPC and subnets.
  3. Update Route Tables: Direct traffic to the firewall endpoint.

Best Practices

  • Use a separate inspection VPC for centralized traffic inspection (Transit Gateway architecture).
  • Combine with AWS WAF for application-layer protection.
