CLOUD LABS
Controlling VPC Traffic Using Network ACLs
In this Cloud Lab, you will utilize network access control lists (NACLs) within Amazon VPC to secure and manage inbound network traffic at the subnet level.

Learning Objectives
Network access control lists (NACLs) within Amazon Virtual Private Cloud (VPC) are a critical security layer in AWS, which offers stateless packet filtering to manage both inbound and outbound traffic at the subnet level. NACLs enable fine-tuned control over network traffic, allowing the enforcement of specific rules based on IP addresses, protocols, and port numbers, ensuring that each subnet within a VPC adheres to tailored security requirements.
In this Cloud Lab, you will examine the default network access control list accompanying a new VPC and understand its permissive nature. You will then move on to the practical aspect of configuring custom NACLs and learn to set specific rules that control traffic based on IP addresses, port numbers, and protocols. You will fetch the Educative instance’s IP address and then update the NACL to restrict traffic from this address. This process will be tested by attempting to access an AWS EC2 instance using the curl command from the identified IP address, demonstrating the effectiveness of the NACL configuration.
By the end of this Cloud Lab, you will understand how to manage NACLs within AWS VPC to implement security measures for the cloud-based networks.

Your method is simple, straight to the point and I can practice with it everywhere, even from my phone, that's something I have never had in other learning platforms.
I highly recommend Educative. The courses are well organized and easy to understand.
I prefer Educative courses because they have a nice mix of text & images. I find that with full video courses, it can often be too easy to go into passive learning mode.
