What tool can be used for network traffic inspection for compliance in a transit VPC architecture?

1. CloudTrail

2. AWS Config

3. Firewall Manager

4. Network Access Control Lists (NACLs)

The correct answer is: Firewall Manager

In a transit VPC architecture, leveraging a tool for network traffic inspection for compliance is crucial for maintaining security and regulatory adherence. Firewall Manager stands out as the appropriate choice because it allows for the centralized management of firewall rules across multiple accounts and VPCs, which enhances the ability to enforce compliance policies. With Firewall Manager, organizations can ensure that all VPCs adhere to agreed security policies by deploying and configuring AWS WAF (Web Application Firewall) rules or security group policies consistently across their environment. This tool not only facilitates automated compliance checks but also provides insights into compliance status and alerts when rules are not being followed. This capability is especially important in a transit VPC setup, where multiple accounts and network paths may be involved, requiring a centralized solution to manage traffic and maintain compliance. The ability to manage and enforce firewalls systematically across various accounts streamlines compliance checks and operational management, making Firewall Manager an effective tool for this purpose. While other options may provide important functionalities for monitoring or controlling network traffic, they do not offer the same level of focused inspection and compliance management specifically designed for transit VPC architectures. CloudTrail, for instance, focuses primarily on logging API calls, AWS Config is more about resource configuration compliance, and network access control lists
