What are Security Groups in AWS?

AWS (Amazon Web Services) security groups are virtual firewalls that dictate traffic for your EC2 (elastic compute cloud) instances. They provide security at the port and protocol level, acting as the first layer of defense against malicious attackers. AWS security groups function in the same manner as firewalls, but with more advanced capabilities. They contain a set of rules that filter both incoming and outgoing traffic for an EC2 instance, which gives additional security for your business.
