You can secure your VPC instances using only security groups. When you launch an instance in a VPC, you can associate one or more security groups that you've created. The security groups act as a firewall for associated Amazon EC2 instances, controlling both inbound and outbound traffic at the instance level. Reference: http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_Security.html
When creating or configuring a security group, you specify the inbound and outbound rules that control the traffic flow to and from the instances. These rules can be based on protocols, ports, IP ranges, and other parameters. Security groups provide a granular level of control over network traffic at the instance level, allowing you to define specific access policies for each instance within your VPC.
In contrast, network ACLs (Access Control Lists) operate at the subnet level in VPC. Network ACLs are stateless and operate at the subnet level, controlling inbound and outbound traffic by evaluating rules based on source and destination IP addresses, ports, and protocols.
