Tonight’s blog post is about adding that extra layer of security to your AWS EC2 instances. Specifically when you have EC2 instances on a private (No inbound traffic) VPC network segment that occasionally need to be accessed. Plan on building yourself at least one bastion host in your public segment and certainly one in each AZ where you have compute power is always a great idea. More importantly protect your key pairs with your life and minimize where they are stored and how they are used. DO NOT store your key pairs on any of your instances! Instead of me writing an article on this topic I found a great very well written article that I would like you to reference and use.
