Why It Matters

The core goal is to rapidly remediate every location where employee information has been exposed within your AWS environment, ensuring you can respond to data breaches before they escalate into regulatory violations. Fixing employee data exposures in AWS is critical for organizations subject to GDPR, as it helps you demonstrate swift incident response and proper data protection measures—mitigating the risk of continued unauthorized access to sensitive HR data.

Primary Risk: Data exposure of employee information

Relevant Regulation: GDPR General Data Protection Regulation

A systematic remediation approach delivers immediate risk reduction, ensuring compliance with breach notification requirements and protecting employee privacy rights.

Prerequisites

Permissions & Roles

  • AWS IAM admin or security incident responder
  • S3:GetBucketPolicy, S3:PutBucketPolicy privileges
  • CloudTrail:LookupEvents for audit trails

External Tools

  • AWS CLI or CloudShell
  • Cyera DSPM account
  • Incident management system

Prior Setup

  • AWS account with proper logging enabled
  • CloudTrail configured
  • Security team contacts identified
  • Breach response procedures documented

Introducing Cyera

Cyera is a modern Data Security Posture Management (DSPM) platform that discovers, classifies, and continuously monitors your sensitive data across cloud services. Using advanced AI-powered Named Entity Recognition (NER) and machine learning models, Cyera automatically identifies exposed employee data in AWS and provides intelligent remediation recommendations, ensuring you can respond to incidents quickly while maintaining GDPR compliance requirements.

Step-by-Step Guide

1
Assess and prioritize exposed resources

Review the incident details from Cyera or security alerts. Identify which AWS resources (S3 buckets, RDS instances, etc.) contain exposed employee data and prioritize based on sensitivity and exposure scope.

2
Immediate containment actions

Implement emergency access controls to stop further exposure. Update bucket policies, security groups, or IAM permissions to restrict access to the minimum necessary personnel during remediation.

3
Remediate the root cause

Fix the underlying misconfigurations that caused the exposure. This may involve updating IAM policies, correcting S3 bucket settings, rotating compromised credentials, or implementing proper encryption at rest and in transit.

4
Validate remediation and document

Verify that the exposure has been fully contained using Cyera's continuous monitoring. Document all remediation actions taken, timeline of response, and lessons learned for compliance reporting and future incident prevention.

Best Practices & Tips

Response Time Optimization

  • Implement automated containment workflows
  • Pre-configure emergency access policies
  • Maintain updated incident response playbooks

Root Cause Analysis

  • Review CloudTrail logs for exposure timeline
  • Identify configuration drift patterns
  • Analyze access patterns for suspicious activity

Common Pitfalls

  • Incomplete inventory of exposed resources
  • Overlooking data copies in backups or logs
  • Failing to notify affected employees promptly
