This chapter highlighted best practices for configuring both NACLs and security groups, such as maintaining bidirectional rules for stateless NACLs, rule sequencing for accurate filtering, and using security group references to enable more secure application segmentation. You also reviewed internet gateways, NAT gateways, and egress-only internet gateways, understanding their roles in providing and securing external connectivity.

With this knowledge of VPC security fundamentals, you are well-prepared to design and manage secure...
