Introduction to Security Groups
•
Security Groups are the fundamental of network security in AWS
•
They control how traffic is allowed into or out of our EC2 Instances.
•
Security groups only contain allow rules
•
Security groups rules can reference by IP or by security group
•
Security groups are acting as a “firewall” on EC2 instances
•
They regulate:
◦
Access to Ports
◦
Authorized IP ranges - IPv4 and IPv6
◦
Control of inbound network (from other to the instance)
◦
Control of outbound network (from the instance to other)
