Example Concept: Implementing network segmentation within a VPC involves creating multiple subnets with distinct security groups and network ACLs to isolate sensitive workloads. By using private subnets for critical resources and public subnets for internet-facing components, you can control traffic flow and reduce exposure to potential threats. Additionally, employing security groups to define inbound and outbound rules at the instance level, and network ACLs for subnet-level traffic filtering, enhances the overall security posture.
