Lab 03 — Google Cloud Data & Application Security Assessment

Welcome

Data and applications are among the most valuable assets within any cloud environment.

Organizations rely on Google Cloud Storage to store sensitive information, Cloud Functions to power serverless applications, and Secret Manager to securely manage credentials and encryption secrets.

As a Cloud Penetration Tester, your responsibility is to determine whether these services have been configured securely and whether they adequately protect the organization’s data and applications.

In this lab, you will assess enterprise data security, application security, identity integration, encryption, and secrets management, just as a cloud security consultant would during a real customer engagement.

Business Scenario

CloudNova Technologies has been contracted to perform an application and data security assessment for a software company operating entirely on Google Cloud Platform.

The customer stores confidential business information within Cloud Storage and uses Cloud Functions for serverless APIs and automation.

Management wants assurance that:

Sensitive data is protected.
Applications follow least privilege.
Secrets are securely managed.
Encryption is properly configured.
Security monitoring is enabled.

Your task is to review the environment and provide a consulting-quality security assessment.

Lab Scope

The assessment includes:

Cloud Storage
Cloud Functions
Secret Manager
IAM Integration
Service Accounts
Encryption
Logging
Monitoring
Data Protection

Real-World Consultant Tips

When assessing cloud data and application security:

Classify data before evaluating its protection.
Verify that storage buckets are not publicly accessible unless explicitly required.
Review Service Accounts assigned to Cloud Functions for least privilege.
Never assume encryption alone is sufficient—validate access controls and key management.
Ensure secrets are retrieved from Secret Manager rather than embedded in source code or configuration files.
Confirm that application, storage, and secret access events are logged and monitored.
Always support findings with evidence and prioritize remediation based on business impact.
