AWS Incident Response: Isolating your EC2 instances

2m 3s

This lesson covers a few strategies for isolating your EC2 instances in response to a security event and explores the pros and cons of those strategies.

Learning Objectives

  • Learn how to isolate an EC2 instance's network communication with various levels of granularity 
  • Understand the positives and negatives associated with each technique

Intended Audience

I would recommend this lesson for any solutions architects, developers, system administrators, and network administrators who are responsible for the security of their architectures.


To get the most out of this lesson, you should have a decent understanding of cloud computing and cloud architectures, specifically with Amazon Web Services. You should know about VPC, Security groups, NACLS, and all the basic level networking concepts for AWS. It would be helpful if you had some background in IT or network security, but it's not required.
