Why It Matters

The core goal is to identify and remediate every instance where audit logs are inadvertently exposed in your Google Cloud Platform environment, protecting sensitive operational data from unauthorized access. Fixing audit log exposures in GCP is critical for organizations subject to SOC 2 compliance, as it helps you maintain proper controls over system activity monitoring and prevent the disclosure of sensitive infrastructure details.

Primary Risk: Data exposure through misconfigured audit log access

Relevant Regulation: SOC 2 Security and Availability Criteria

Proper remediation ensures that audit logs remain accessible only to authorized personnel while maintaining comprehensive security monitoring capabilities.

Prerequisites

Permissions & Roles

  • Project Editor or Owner role
  • Logging Admin or Security Admin role
  • IAM Admin permissions for role modifications

External Tools

  • Google Cloud CLI (gcloud)
  • Cyera DSPM account
  • Cloud Console access

Prior Setup

  • GCP project with audit logging enabled
  • Cloud Logging API enabled
  • Security Command Center activated
  • IAM policies reviewed

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 and natural language processing (NLP) techniques, Cyera automatically identifies exposed audit logs in GCP by analyzing log content patterns, access permissions, and data sensitivity markers. This ensures you can quickly remediate audit log exposures while maintaining SOC 2 compliance requirements in real time.

Step-by-Step Guide

1
Audit current log sink configurations

Review all existing log sinks and their destinations to identify potential exposure vectors. Check for overly permissive IAM bindings on log buckets and pub/sub topics.

2
Configure secure log storage

In the Cyera portal, navigate to Integrations → DSPM → Add new. Select GCP, provide your service account credentials, then initiate a comprehensive scan to identify all exposed audit log locations across your organization.

3
Implement access controls and encryption

Apply principle of least privilege to all audit log access, enable customer-managed encryption keys (CMEK) for log storage, and configure VPC Service Controls to restrict log data movement.

4
Validate remediation and establish monitoring

Verify that all identified exposures have been resolved, establish continuous monitoring alerts for new log sink creations, and implement automated compliance checks to prevent future exposures.

Best Practices & Tips

Access Control Strategy

  • Use dedicated service accounts for log processing
  • Implement time-bound access with IAM conditions
  • Regular audit of log viewer permissions

Log Retention & Storage

  • Configure appropriate retention policies
  • Use separate projects for log storage
  • Enable object versioning for tamper protection

Common Pitfalls

  • Exposing logs through public BigQuery datasets
  • Overly broad IAM roles on log buckets
  • Forgetting to secure custom log sinks
