This course is about how AWS IAM works and how to write policies to control access in an AWS account. In this course, you will learn how AWS APIs work, explore different parts of the requests made to the APIs and elaborates on how access is determined. Additionally, you will dive into how to configure access inside AWS by describing the policy structure and the 5 policy types AWS supports.

Further, you will become familiar with how the elements in the request and the policies fit together. You will also determine whether the operation is allowed or denied by demonstrating through several step-by-step realistic examples that show exactly how IAM evaluates access, thus providing templates for how to apply these protections to AWS environments.

Lastly, this course offers you some practical tips on how to secure an account both as an administrator and as a developer. It explains the best practices and the usual pitfalls of AWS security.

AWS Security Fundamentals: A Practical Guide to AWS IAM

IAM controls access to *AWS APIs only*. While this is a broad surface, it does not contain everything.

# Use of APIs in AWS
Writing an object to an S3 bucket is done [through the API](https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutObject.html). Similarly, creating new buckets, changing the metadata of existing objects, and setting up bucket replication are all done through the API and thus protected by IAM.

Apart from S3, invoking Lambda functions, starting EC2 instances, getting a list of IAM users in the account is all done through their respective APIs.

Learn how AWS APIs work, what their role is, and what the IAM controls can access.
