Securing Your S3 Bucket from A to Z

In this hands-on lab, we implement S3 bucket policies and IAM policies to learn about the various ways to secure our S3 buckets and the data within them. We also examine which services we can leverage to audit and remediate security issues. Here is the [GitHub link](https://raw.githubusercontent.com/linuxacademy/content-how-to-properly-secure-an-s3-bucket/master/lab-securing-s3-a-to-z/S3BucketPolicy.json) to copy the S3 bucket policy mentioned in this lab.
