AWS Tutorial AWS Solutions Architect and SysOps Administrator - Network ACLs Versus Security Groups

This lecture explains the differences between Network ACL and Security Group in AWS. Security Groups operate at the instance level and are stateful, meaning inbound rules automatically apply to outbound traffic. Network ACLs operate at the subnet level and are stateless, requiring explicit rules for both inbound and outbound traffic. The video also demonstrates how to create and manage Network ACLs using the AWS Management Console.
