Fundamentals of Aws Security Groups and NACL

Abstract: AWS Security Groups and NACL, namely Network Access Control List act as a safeguard to protect the network and manage the incoming and outgoing data flow say traffic or data stream based on the specified rules and allow only authorized users to access the resources. There is a basic variance between security groups and NACLs in that security groups are actually a virtual firewall for EC2 instances, whereas NACLs work for subnets. The chapter highlights the security groups & NACL working, limitations and significance of integrating both.
