Security groups are a feature in AWS that allow you to control the inbound and outbound traffic to

your instances. They act as a virtual firewall that can filter the traffic based on the source,

destination, protocol, and port. You can assign one or more security groups to your instances, and

each security group can have multiple rules. Security groups are stateful, meaning that they

automatically allow the response traffic for any allowed inbound traffic, and vice versa. Security

groups are essential for securing your nodes in the AWS EKS cluster, as they can prevent

unauthorized access to your Mongo Atlas database or other resources. You can also use security

groups to isolate your nodes from other instances in the same VPC or subnet, or to allow

communication between nodes in different clusters or regions. Reference :=
