How to Create Security Groups on Amazon Web Service (AWS)

A security group acts as a virtual firewall for your EC2 instances to control incoming and outgoing traffic. If you don’t specify a security group, Amazon EC2 uses the default security group. You can add rules to each security group that allow traffic to or from its associated instances.

 

  • Login to aws portal.
  • Click on Services.
