What are Security Groups?
Security Groups are stateful managed firewalls. A security group controls incoming and outgoing traffic for your EC2 instances by acting as a virtual firewall. Inbound rules manage incoming traffic to your instance. Whereas, outbound rules govern incoming traffic from your instance. Users can define one or even more security groups when launching an instance.
For example, a policy that states that all instances with the tag “Naukri 1” within “Shiksha Online organization 1” will be subject to the “Naukri 1” policy. This means that all EC2 instances with that tag in that organizational unit will be assigned the same security group. And as an added bonus, the Firewall Manager will continuously monitor compliance policy
