AWS Security Foundations Lab 4.1: Securing VPC Resources by Using Security Groups - Anand K

Lab 4.1: Securing VPC Resources by Using Security Groups Lab overview and objectives Security groups are virtual firewalls that are attached to Amazon Elastic Compute Cloud (Amazon EC2) instances. Security group rules define what traffic is allowed in or out of an instance. In this lab, you are tasked to configure access rules for EC2 instances. After completing this lab, you should be able to do the following: Examine security groups to determine what traffic is allowed. Change which security groups are applied to EC2 instances. Create new security groups. Update the inbound rules on security groups to follow the principle of least privilege. Understand how security groups can reference other security groups. Configure a network access control list (ACL) to block traffic on a specific TCP port. Connect to an instance in a private subnet by using SSH. Connect to an instance in a private subnet by using AWS Systems Manager Session Manager.
