Network Access Control Lists (NACLs)

2m 26s

This lesson looks at some of the different methods that AWS implements to authorize access within your AWS account, whether this is a user requiring access to an AWS service, or a network packet trying to reach its destination.

Learning Objectives

  • Learn how authorization is granted when working within your AWS account
  • Understand how S3 handles its own authorization mechanisms
  • Use network access control lists to authorize network packets to enter and leave different parts of your VPC
  • Learn how AWS security groups provide security at the protocol and port access level

Intended Audience

  • AWS Administrators
  • Security Engineers
  • Security Architects
  • Anyone looking to increase their knowledge of security and how authorization is governed within AWS


To get the most out of this lesson you should have a basic understanding of AWS IAM, Amazon S3, VPCs, and EC2, but this is not essential.
