Why It Matters

The core goal is to proactively secure all unstructured data stored across your GCP environment, preventing accidental exposures before they become compliance violations. Protecting unstructured data in GCP is critical for organizations subject to GDPR, as it helps you ensure personal data remains secure throughout its lifecycle—mitigating the risk of data exposure and potential regulatory penalties.

Primary Risk: Data exposure through misconfigured storage buckets and improper access controls

Relevant Regulation: GDPR General Data Protection Regulation

A comprehensive prevention strategy delivers continuous protection, ensuring automated policy enforcement and ongoing compliance across all GCP services handling unstructured data.

Prerequisites

Permissions & Roles

  • GCP Project Owner or Security Admin
  • Cloud Storage Admin privileges
  • DLP API and Sensitive Data Protection access

External Tools

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

Prior Setup

  • GCP project provisioned
  • Cloud Storage buckets configured
  • IAM policies defined
  • 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 Natural Language Processing (NLP) models, Cyera automatically identifies and protects unstructured data in GCP environments, ensuring you proactively prevent exposures and maintain GDPR compliance through intelligent data discovery and risk assessment.

Step-by-Step Guide

1
Configure GCP security baseline

Enable Cloud Asset Inventory, set up uniform bucket-level access, and configure default encryption for all Cloud Storage buckets containing unstructured data.

2
Deploy preventive data protection policies

In the Cyera portal, navigate to Integrations → GCP → Add new. Configure service account credentials, enable automated scanning of Cloud Storage, BigQuery, and Firestore, then set up real-time protection policies to prevent unauthorized access.

3
Implement access controls and monitoring

Configure Cloud IAM policies with least privilege principles, set up Cloud Logging for data access auditing, and integrate with Security Command Center for centralized threat detection and response.

4
Establish continuous compliance workflows

Set up automated remediation workflows, configure alerting for policy violations, and establish regular compliance reporting. Schedule periodic access reviews and implement data retention policies aligned with GDPR requirements.

Best Practices & Tips

Access Control Strategy

  • Implement least privilege IAM policies
  • Use Cloud Identity for centralized access management
  • Enable multi-factor authentication for admin access

Data Protection Measures

  • Enable encryption at rest and in transit
  • Configure VPC Service Controls for data perimeter
  • Implement Cloud KMS for key management

Common Pitfalls

  • Leaving default bucket permissions too permissive
  • Neglecting to monitor cross-project data access
  • Failing to implement data lifecycle management
