AWS customers use multiple security services to build strong network defenses, but visibility into threats, misconfigurations, and vulnerabilities across multi-VPC and multi-account environments can remain a challenge. This session covers AWS network security fundamentals - Security Groups, NACLs, Network Firewall, DNS Firewall, and Gateway Load Balancer - for a layered defense strategy. We will also highlight observability tools like VPC Flow Logs, Reachability Analyzer, and Network Access Analyzer to detect security gaps and troubleshoot access issues. By integrating these tools, organizations can proactively enhance network security, detect vulnerabilities, and ensure secure, scalable architectures across AWS accounts and environments.
