In this episode you will learn:
- AWS WAF protects web applications at Layer 7 from exploits like SQL injection, and is associated with CloudFront and Application Load Balancers.
- AWS Network Firewall is a managed, stateful firewall for VPCs that provides centralized, network-level traffic filtering and inspection.
- Security Groups are stateful firewalls for instances, meaning return traffic is automatically allowed, while Network ACLs are stateless firewalls for subnets, requiring explicit outbound rules for responses.
- VPC Endpoints (Gateway and Interface) enable private and secure connectivity from a VPC to AWS services without traversing the public internet.
- AWS PrivateLink is the underlying technology for Interface Endpoints that allows private connections to AWS services, third-party services, and services in other VPCs.
