Concepts
Amazon Macie is a fully managed data security and data privacy service that uses machine learning and pattern matching to discover and protect sensitive data in AWS. Macie is designed to recognize sensitive data such as personally identifiable information (PII), or intellectual property, and provides dashboards and alerts that give visibility into how this data is being accessed or moved.
For example, to get started with Macie, an AWS Certified Data Engineer might set up a job to scan S3 buckets:
import boto3
macie2 = boto3.client(‘macie2′)
# Create a classification job
response = macie2.create_classification_job(
clientToken=’string’,
s3JobDefinition={
‘bucketDefinitions’: [
{
‘accountId’: ‘123456789012’,
‘buckets’: [‘example-bucket’]
},
],
},
samplingPercentage=100,
scheduleFrequency={
‘dailySchedule’: {}
},
jobType=’ONE_TIME’,
name=’example-job’,
description=’An example job to classify S3 data.’
)
This job will check all files in the specified bucket and alert you to any sensitive information that it finds.
AWS CloudTrail
AWS CloudTrail is a service that enables governance, compliance, operational auditing, and risk auditing of your AWS account. CloudTrail logs, continuously monitors, and retains account activity related to actions across your AWS infrastructure, providing a history of AWS API calls for your account, including API calls made via the AWS Management Console, AWS SDKs, command line tools, and other AWS services.
A classic use case involves setting up a trail to monitor for specific API activity:
import boto3
cloudtrail = boto3.client(‘cloudtrail’)
# Create a trail
response = cloudtrail.create_trail(
Name=’example-trail’,
S3BucketName=’example-bucket’,
IsMultiRegionTrail=True,
IncludeGlobalServiceEvents=True
)
# Start logging
response = cloudtrail.start_logging(
Name=’example-trail’
)
With this trail, you would have logs of all the specified AWS API calls that you can analyze to check for unusual or unauthorized activity.
Amazon CloudWatch
Amazon CloudWatch is a monitoring and management service built for developers, system operators, site reliability engineers (SRE), and IT managers. CloudWatch provides data and actionable insights to monitor your applications, respond to system-wide performance changes, optimize resource utilization, and get a unified view of operational health.
Here’s an example of a Data Engineer using CloudWatch to monitor the CPU utilization of EC2 instances:
import boto3
cloudwatch = boto3.client(‘cloudwatch’)
# Put a custom metric data
response = cloudwatch.put_metric_data(
Namespace=’AWS/EC2′,
MetricData=[
{
‘MetricName’: ‘CPUUtilization’,
‘Dimensions’: [
{
‘Name’: ‘InstanceId’,
‘Value’: ‘i-1234567890abcdef0’
},
],
‘Unit’: ‘Percent’,
‘Value’: 75.0
},
]
)
This data is invaluable for triggering alerts or taking automated actions if the CPU utilization goes beyond a defined threshold.
Comparing Macie, CloudTrail, and CloudWatch
| Service | Primary Use | Use Cases |
|---|---|---|
| Amazon Macie | Data security and privacy | Identifying and protecting sensitive data in S3 |
| AWS CloudTrail | Governance, compliance, auditing, and risk auditing | Logging and monitoring API calls across AWS |
| Amazon CloudWatch | Monitoring and management | Watching for metrics or events for AWS services |
AWS Certified Data Engineers should understand how to leverage these services to ensure data security, compliance, and operational integrity. By incorporating Macie, CloudTrail, and CloudWatch into their AWS environment, Data Engineers can help maintain high standards for data privacy, auditability, and operational excellence.
