AWS Macie: Enhancing Data Security and Compliance

What is AWS Macie?

AWS Macie is designed to provide:

• Data discovery: It automatically scans your Amazon S3 buckets to identify sensitive data such as Personally Identifiable Information (PII), financial data, or intellectual property.

• Data security: By detecting unprotected or overly accessible sensitive data, Macie helps reduce the risk of data breaches.

• Data compliance: It aids in maintaining compliance with data privacy regulations like GDPR, HIPAA, and CCPA.

Macie leverages advanced ML techniques to classify data, alert you to potential risks, and provide insights into data usage patterns.

How does Macie work?

Macie will produce your S3 bucket list in the region where you enabled it within a few minutes of allowing Macie for your AWS account. Macie will also begin to keep an eye on the buckets’ security and access control. It generates thorough findings when it identifies the potential of illegal access or any inadvertent data disclosure.

Macie has three main features:

1. Macie summary dashboard

The dashboard gives you a quick overview of how the data is accessed and moved. The total number of buckets, objects, and S3 storage consumed are all displayed on this dashboard.

It also divides S3 buckets into public, encrypted, and private buckets, as well as buckets shared within and outside your AWS account or AWS company.

2. Macie Jobs

Create and run sensitive data discovery jobs in Amazon S3 buckets to automatically discover, record, and report sensitive data.

You can set the job to run only once for on-demand analysis or schedule it to run on a regular basis for recurring analysis and monitoring.

3. Macie’s Findings

A finding is a detailed report of potential policy violations for sensitive data in S3 buckets or S3 objects. Macie provides two types of findings: policy findings and sensitive data findings.

Macie can also send all findings to Amazon CloudWatch Events so you can build custom remediation and alert management.

Examples of policy findings are below.

Examples of sensitive data findings below

In every Macie finding, you will find detailed info.
