CoreAWS Network Firewall
Explicit network-protection audit example.
Key points
- Network Firewall applies stateful and stateless inspection to routed VPC traffic at its configured associations and rules.
Best-known use cases
- D4.1, D4.2, and D5.1: audit or troubleshoot the named VPC traffic-protection path and its logs.
What candidates often confuse it with
- Network Firewall inspects VPC traffic; WAF evaluates supported web requests and DNS Firewall evaluates DNS queries.
Key takeaway
Verify routing through the firewall, rule behavior, associations, and logs at the VPC traffic layer.
