Why It Matters

The core goal is to proactively secure every location where employee information is stored within your Google Cloud Platform environment, preventing unauthorized access before it becomes a data breach. Preventing employee data exposure in GCP is critical for organizations subject to GDPR, as it helps you maintain strict data protection standards and avoid costly regulatory penalties.

Primary Risk: Data exposure of sensitive employee information

Relevant Regulation: GDPR General Data Protection Regulation

A comprehensive prevention strategy delivers proactive security controls, automated policy enforcement, and continuous compliance monitoring.

Prerequisites

Permissions & Roles

  • GCP Project Owner or Editor role
  • Security Admin and IAM Admin privileges
  • Cloud DLP API access

External Tools

  • Google Cloud CLI (gcloud)
  • Cyera DSPM account
  • Service account credentials

Prior Setup

  • GCP project provisioned
  • IAM policies configured
  • Cloud DLP API enabled
  • Network security rules in place

Introducing Cyera

Cyera is a modern Data Security Posture Management (DSPM) platform that discovers, classifies, and continuously monitors your sensitive data across cloud services. By leveraging advanced AI and Named Entity Recognition (NER) models, Cyera automatically identifies employee data patterns in your GCP environment and implements proactive security controls to prevent unauthorized exposure before it occurs.

Step-by-Step Guide

1
Configure IAM and access controls

Implement least-privilege access policies using GCP IAM. Create dedicated service accounts for data processing and restrict employee data access to authorized personnel only.

gcloud iam service-accounts create employee-data-access --display-name="Employee Data Access"

2
Enable Cloud DLP and data classification

In the Cyera portal, navigate to Integrations → DSPM → Add new. Select Google Cloud Platform, provide your project details and service account credentials, then configure automated data classification rules for employee data.

3
Implement preventive security policies

Configure automated policy enforcement to block unauthorized access attempts, encrypt employee data at rest and in transit, and set up real-time monitoring for sensitive data movement.

4
Establish continuous monitoring

Deploy continuous scanning workflows to monitor for new employee data stores, validate encryption status, and ensure access controls remain properly configured. Set up automated alerts for policy violations.

Best Practices & Tips

Access Control Strategy

  • Implement principle of least privilege
  • Use conditional access policies
  • Regular access reviews and audits

Data Protection Measures

  • Enable encryption at rest and in transit
  • Use customer-managed encryption keys
  • Implement data residency controls

Common Pitfalls

  • Overly permissive bucket policies
  • Unencrypted data stores and backups
  • Missing monitoring for service accounts
