Macie automatically evaluates your S3 bucket inventory on a daily basis and identifies objects containing PII, financial information, credentials, and other sensitive data types. It provides two discovery approaches: automated sensitive data discovery for broad visibility and targeted discovery jobs for deep analysis. ## When to Use - When deploying or configuring implementing aws macie for data classification capabilities in your environment - When establishing security controls aligned to compliance requirements - When building or improving security architecture for this domain - When conducting security assessments that require this implementation ## Prerequisites - AWS account with S3 buckets containing data to classify - IAM permissions for Macie service configuration - AWS Organizations setup (for multi-account deployment) - S3 buckets in supported regions ## Enable Macie ### Via AWS CLI ```bash # Enable Macie in the current account/region aws macie2 enable-macie # Verify Macie is enabled aws macie2 get-macie-session # Enable automated sensitive data discovery aws macie2 update-automated-discovery-configuration \ --status ENABLED ``` ### Via Terraform ```hcl resource "aws_macie2_account" "main" {} resource "aws_macie2_classification_export_configuration" "main" { depends_on = [aws_macie2_account.main] s3_destination { bucket_name = aws_s3_bucket.macie_results.id key_prefix = "macie-findings/" kms_key_arn = aws_kms_key.macie.arn } } ``` ## Configure Discovery Jobs ### Create a classification job for specific buckets ```bash aws macie2 create-classification-job \ --job-type ONE_TIME \ --name "pii-scan-production-buckets" \ --s3-job-definition '{ "bucketDefinitions": [{ "accountId": "123456789012", "buckets": [ "production-data-bucket", "customer-records-bucket" ] }] }' \ --managed-data-identifier-selector ALL ``` ### Create a scheduled recurring job ```bash aws macie2 create-classification-job \ --job-type SCHEDULED \ --name "weekly-sensitive-data-scan" \ --schedule-frequency-details '{ "weekly": { "dayOfWeek": "MONDAY" } }' \ --s3-job-definition '{ "bucketDefinitions": [{ "accountId": "123456789012", "buckets": ["all-data-bucket"] }], "scoping": { "includes": { "and": [{ "simpleScopeTerm": { "comparator": "STARTS_WITH", "key": "OBJECT_KEY", "values": ["uploads/", "documents/"] } }] } } }' ``` ## Custom Data Identifiers ### Create a custom identifier for internal IDs ```bash aws macie2 create-custom-data-identifier \ --name "internal-employee-id" \ --description "Matches internal employee ID format EMP-XXXXXX" \ --regex "EMP-[0-9]{6}" \ --severity-levels '[ {"occurrencesThreshold": 1, "severity": "LOW"}, {"occurrencesThreshold": 10, "severity": "MEDIUM"}, {"occurrencesThreshold": 50, "severity": "HIGH"} ]' ``` ### Create identifier for project codes ```bash aws macie2 create-custom-data-identifier \ --name "project-code-identifier" \ --description "Matches project codes in format PRJ-XXXX-XX" \ --regex "PRJ-[A-Z]{4}-[0-9]{2}" \ --keywords '["project", "code", "initiative"]' \ --maximum-match-distance 50 ``` ## Allow Lists ### Create an allow list to suppress false positives ```bash aws macie2 create-allow-list \ --name "test-data-exclusions" \ --description "Exclude known test data patterns" \ --criteria '{ "regex": "TEST-[0-9]{4}-[0-9]{4}-[0-9]{4}-[0-9]{4}" }' ``` ## Managed Data Identifiers Macie provides 300+ managed data identifiers covering: | Category | Examples | |----------|---------| | **PII** | SSN, passport numbers, driver's license, date of birth, names, addresses | | **Financial** | Credit card numbers, bank account numbers, SWIFT codes | | **Credentials** | AWS secret keys, API keys, SSH private keys, OAuth tokens | | **Health** | HIPAA identifiers, health insurance claim numbers | | **Legal** | Tax identification numbers, national ID numbers | ## Findings Management ### List findings ```bash # Get sensitive data findings aws macie2 list-findings \ --finding-criteria '{ "criterion": { "severity.description": { "eq": ["High"] }, "category": { "eq": ["CLASSIFICATION"] } } }' \ --sort-criteria '{"attributeName": "updatedAt", "orderBy": "DESC"}' \ --max-results 25 ``` ### Get finding details ```bash aws macie2 get-findings \ --finding-ids '["finding-id-1", "finding-id-2"]' ``` ### Export findings to Security Hub ```bash # Macie automatically publishes findings to Security Hub # Verify integration: aws macie2 get-macie-session --query 'findingPublishingFrequency' ``` ## EventBridge Integration for Automated Response ```json { "source": ["aws.macie"], "detail-type": ["Macie Finding"], "detail": { "severity": { "description": ["High", "Critical"] } } } ``` ### Lambda function for automated remediation ```python import boto3 import json s3 = boto3.client('s3') sns = boto3.client('sns') def lambda_handler(event, context): finding = event['detail'] severity = finding['severity']['description'] bucket = finding['resourcesAffected']['s3Bucket']['name'] key = finding['resourcesAffected']['s3Object']['key'] sensitive_types = [d['type'] for d in finding.get('classificationDetails', {}).get('result', {}).get('sensitiveData', [])] if severity in ['High', 'Critical']: # Tag the object for review s3.put_object_tagging( Bucket=bucket, Key=key, Tagging={ 'TagSet': [ {'Key': 'macie-finding', 'Value': severity}, {'Key': 'sensitive-data', 'Value': ','.join(sensitive_types)}, {'Key': 'requires-review', 'Value': 'true'} ] } ) # Notify security team sns.publish( TopicArn='arn:aws:sns:us-east-1:123456789012:security-alerts', Subject=f'Macie {severity} Finding: {bucket}/{key}', Message=json.dumps({ 'bucket': bucket, 'key': key, 'severity': severity, 'sensitive_data_types': sensitive_types, 'finding_id': finding['id'] }, indent=2) ) return {'statusCode': 200} ``` ## Multi-Account Deployment ### Designate Macie administrator account ```bash # From the management account aws macie2 enable-organization-admin-account \ --admin-account-id 111111111111 ``` ### Add member accounts ```bash # From the administrator account aws macie2 create-member \ --account '{"accountId": "222222222222", "email": "security@example.com"}' ``` ## Monitoring Macie Operations ### Usage statistics ```bash aws macie2 get-usage-statistics \ --filter-by '[{"comparator": "GT", "key": "accountId", "values": []}]' \ --sort-by '{"key": "accountId", "orderBy": "ASC"}' ``` ### Classification job status ```bash aws macie2 list-classification-jobs \ --filter-criteria '{"includes": [{"comparator": "EQ", "key": "jobStatus", "values": ["RUNNING"]}]}' ``` ##
