What is the purpose of AWS Security Groups?

b) To manage user identities
c) To automate scaling of EC2 instances
d) To enable data encryption
Answer:
a) To control inbound and outbound traffic to AWS resources
Explanation:
AWS Security Groups act as virtual firewalls for your EC2 instances, controlling inbound and outbound traffic. Users can define rules for allowing or denying specific types of traffic based on IP addresses, protocols, and ports.
Security Groups provide an extra layer of security by controlling which network traffic can access EC2 instances and other AWS resources. They are stateful, meaning that changes made to inbound rules automatically apply to outbound traffic as well.
Using Security Groups, users can manage and secure network access to their AWS resources effectively, helping to ensure data integrity and protection against unauthorized access.
