Amazon Macie is a fully managed security service which continuously monitors the data in AWS environment based on content type, file type, regular expression etc. set by IT administrator. It uses machine learning to discover, classify, and protect sensitive information in AWS. It provides dashboards and alerts by which an administrator knows how the data is being accessed. It can also discover and report the occurrence of certain important files like .pem key in an S3 Bucket, or a publicly accessible S3 Bucket. Currently, Macie is available for S3, in a few AWS Regions.
