AWS, JavaScript, React - Deploy Web Apps on the Cloud - Introduction to Security Groups

The video tutorial explains AWS security groups, which act as virtual firewalls for instances, controlling inbound and outbound traffic. Instances can be assigned up to five security groups, with default assignments if unspecified. Security groups consist of rules that filter traffic based on protocols and port numbers. These rules are divided into inbound and outbound categories, with AWS allowing only allow rules. By default, security groups have no inbound rules, denying all inbound traffic, while allowing all outbound traffic unless specified otherwise. The tutorial concludes with a preview of a practical guide to reinforce the concepts discussed.

Describe the difference between inbound and outbound rules in a security group.

What is the default behavior of outbound traffic in a newly created security group?
