Why It Matters

The core goal is to proactively prevent API keys, secrets, and tokens from being exposed within your Google Cloud Platform environment. Establishing proper secret management practices in GCP is critical for organizations pursuing SOC 2 compliance, as it demonstrates you have controls in place to protect authentication credentials from unauthorized access and potential misuse.

Primary Risk: Insecure APIs and exposed authentication credentials

Relevant Regulation: SOC 2 Trust Services Criteria

Implementing comprehensive secret management delivers immediate security improvements, establishing automated safeguards and maintaining audit trails for compliance reporting.

Prerequisites

Permissions & Roles

  • Project Editor or Security Admin role
  • Secret Manager Admin privileges
  • IAM Security Reviewer access

External Tools

  • Google Cloud CLI (gcloud)
  • Cyera DSPM account
  • Terraform (optional)

Prior Setup

  • GCP project provisioned
  • Secret Manager API enabled
  • IAM policies configured
  • Audit logging enabled

Introducing Cyera

Cyera is a modern Data Security Posture Management (DSPM) platform that uses advanced AI and machine learning models to automatically discover, classify, and monitor sensitive credentials across cloud environments. Through pattern recognition and Named Entity Recognition (NER), Cyera identifies API keys, tokens, and secrets that may be inadvertently exposed in code repositories, configuration files, or data stores within your GCP environment, ensuring continuous protection against credential exposure.

Step-by-Step Guide

1
Enable Secret Manager and configure IAM

Enable the Secret Manager API in your GCP project and establish proper IAM roles with least-privilege access. Create dedicated service accounts for secret management operations.

gcloud services enable secretmanager.googleapis.com

2
Implement Workload Identity Federation

Configure Workload Identity to eliminate service account keys in GKE environments. Bind Kubernetes Service Accounts to Google Service Accounts for seamless, keyless authentication.

3
Set up automated secret scanning

In the Cyera portal, configure GCP integration to continuously monitor repositories, configuration files, and runtime environments for exposed credentials. Enable real-time alerts for policy violations.

4
Establish secret rotation policies

Configure automatic secret rotation schedules in Secret Manager, implement version management, and establish automated workflows to update applications when secrets are rotated.

Best Practices & Tips

Secret Management

  • Never hardcode secrets in source code
  • Use Secret Manager for all sensitive data
  • Implement automatic rotation policies

Access Control

  • Apply principle of least privilege
  • Use Workload Identity where possible
  • Regularly audit IAM permissions

Common Pitfalls

  • Storing secrets in environment variables
  • Using long-lived service account keys
  • Insufficient logging and monitoring
