I've drawn upon a number of best practices, security guidelines, and government department information security recommendations to create my own set of general recommendations on how to secure your AWS Cloud.

It is important to understand that these are my general recommendations and that while I've tried to make them applicable to a variety of situations, you will need to tailor them your specific situation.
