热门Configures AWS Network Firewall, the managed stateful VPC firewall: deploying a firewall and routing traffic through its endpoints; centralizing inspection for many VPCs with a transit gateway-attached firewall that keeps stateful flows symmetric across Availability Zones; filtering outbound traffic by domain name; logging and rule tuning; TLS inspection with ACM certificates; writing Suricata rules; managing rules as CloudFormation/IaC; blocking an indicator mid-incident; migrating off a third-party firewall appliance; and diagnosing dropped traffic. Applicable when the user wants to inspect or filter VPC traffic at Layer 3 and 4, allow or block outbound domains, manage firewall rules as IaC, or decrypt TLS. Not applicable for AWS WAF Layer 7 rules (waf skill), Gateway Load Balancer appliance inspection (gatewayloadbalancer skill), Route 53 Resolver DNS Firewall (route53 skill), or transit gateway route tables and appliance-mode attachments (transitgateway skill).

Network Firewall
Overview
Domain expertise for configuring AWS Network Firewall, the managed stateful firewall and intrusion
prevention service that filters traffic at the perimeter of a VPC using the Suricata inspection
engine. Covers placing a firewall in the traffic path and routing traffic through its endpoints,
centralizing inspection across VPCs with a transit gateway-attached firewall, filtering outbound
traffic by domain name, logging and rule tuning, TLS inspection of encrypted traffic, and
diagnosing why traffic is dropped, passed, or unmatched.
This skill is a router. Each customer task maps to a reference file under references/. Read the
matching reference in full before acting, then follow its constraints and steps. The reference
files are self-contained: each carries its own decision tables, constraints, procedure, and
troubleshooting.
