What service would you use to manage network security in AWS?

To manage network security in AWS, the Virtual Private Cloud (VPC) service is the appropriate choice. VPC enables you to create a logically isolated section of the AWS cloud where you can define your own virtual network topology. This includes selecting the IP address range, creating subnets, and configuring route tables and network gateways, which is essential for controlling both inbound and outbound traffic.

With VPC, you can also implement security measures such as security groups and network access control lists (ACLs). Security groups act as virtual firewalls for your instances, allowing you to specify rules that govern the traffic permitted to and from the instances. Network ACLs provide an additional layer of security at the subnet level, enabling more granular control over traffic flows.

Other services mentioned, while important in their own contexts, do not primarily focus on managing network security. For example, CloudFront is a Content Delivery Network (CDN) that optimizes the delivery of static and dynamic web content rather than managing network security directly. IAM (Identity and Access Management) controls access to AWS resources and services rather than specifically managing network traffic. Amazon S3 is primarily a storage service and does not handle network security management.

Thus, VPC is the key service for managing network security in
