Centralized Network Inspection on AWS Template

The Centralized Network Inspection on AWS template is a setup that helps you manage network traffic coming in and going out of multiple VPCs. It uses AWS Transit Gateway, AWS Network Firewall, and Gateway Load Balancer (GWLB) to achieve a single point of inspection where all your VPCs are integrated.

You can track traffic, create firewall rules, and manage updates in one place instead of doing it separately on each VPC. It even works with AWS CodePipeline and will automatically update your security configuration when you need to.

This setup is advantageous to small and large AWS environments to an equal extent. It offers greater control, less human intervention, and helps maintain your network safe and organized.
 

What is the template useful for? 

Manually managed security on many VPCs takes time. You can miss a threat, apply the wrong rule, or have trouble monitoring network traffic.

This Centralized Network Inspection on AWS template fills that gap by:

• Traffic monitoring centralized: You can observe what is occurring in all of your VPCs at one location.
   
• Implementing firewall rules universally: No duplication of the same configuration in every VPC.
   
• Automated updating: Rule changes can be tested and implemented  Automatically.
   
• Improving security: Everything is scanned before it hits your workload.
   
• Simplification of routing: Transit Gateway manages routing, and traffic passes through the inspection layer.

It’s a neat solution that keeps things under control as your cloud usage grows.
 

Who Can Use It, and When? 

This template is most appropriate for: 

• Groups that work across several AWS VPC.

• Companies subject to security and compliance laws.

• Cloud administrators looking to make network monitoring easier.

• Organizations that plan to scale their AWS infrastructure.

You can employ it when: 

• You're building a new AWS project with multiple VPCs.

• Your current network is becoming difficult to handle.

• You need better control and visibility of network traffic.

• You want to change from manual to automatic security updates.
   

Main Components of The Template 

Below is a clear summary of the main points:

• AWS Transit Gateway: Connects all your VPCs and directs their traffic through the inspection configuration.

• AWS Network Firewall: Blocks and inspects traffic based on rules that you specify.

• Gateway Load Balancer (GWLB): Controls and scales firewall devices.

• AWS CodePipeline: Streamlines the process of updating firewall rules.

• AWS CodeBuild: Checks for changes to firewall rules before implementing.

• AWS CodeCommit: Keeps your firewall rules under version control.

• AWS KMS: Controls encryption for secure storage and communication.

• AWS IAM Roles: Determines who can access and manage the components.

• Firewall Route Table: Directs traffic to pass through the inspection subnet.

• Firewall Private Subnet: Restricts the firewall services to a private, safe network.

• VPC Inspection Subnet: Where traffic is monitored and inspected.

• Spoke VPCs (1, 2, 3): Your application VPCs where workloads are located.

• Security Logging: Logs all the firewall traffic for auditing and monitoring.

• AWS Organizations: Enables you to apply security and governance policies to accounts.

All of these factors make it easy and secure to inspect the network.
